Oh my goodness you guys. A travesty happened right when I was in the middle of making these cookies.

My oven broke. *gasp*

If you follow me on Facebook, Twitter, or Instagram, you probably already know this. In fact, you’re probably all, “quit whining already!”

But guys, it’s my OVEN.

I turned it on to preheat, walked away to make the dough, put them in the pans and went to put them in the oven. There was no heat – just lots and lots of gas. I immediately turned it off, of course. Tried again…no dice.

{The repairman just left an hour ago. He took apart the oven and “jiggled” the ignitor and got it working again – for now. He’s ordering a part to replace it, in case “jiggling” doesn’t solve the issue. In the last hour I have baked mini pies, a cake, and magic bars. I’m not going to stop…because I’m scared if I turn it off it won’t turn on again, ha.}

Anyway, back to these cookies. Thank goodness for my wonderful sister-in-law. She let me come over and hijack her oven on Saturday afternoon so I could bake these cookies for all of you. Because, well. They’re important and time-sensitive cookies.

Have you heard of the new flavors of Frosting Creations that Duncan Hines has released? They have four brand-spanking new flavors available only this month: Pink Lemonade, Key Lime Pie, Peaches and Cream, and Fruit Punch. Cool new flavors in super fun colors for Spring! But they’re only available through March, so get yourself to the store!

I am so excited to have been selected as a one of the bloggers for Duncan Hines’ new Passionate Blogger Program. As part of this program, I get to try out the new flavors of Frosting Creations and share some fun recipes with you! I decided to start with the Key Lime Pie flavor because I am totally crushing on anything citrus right now and even though I’ve never tasted Key Lime anything, my mouth was watering thinking of it!

Believe me, the Key Lime Pie Frosting Creations did not disappoint. It’s the perfect blend of tart and sweet! If you’ve never used Frosting Creations, you must give them a try. I have found that the flavors are really perfect – they actually taste like they are supposed too. You just mix them into your frosting, easy peasy. You can mix them into other things too, like my Mint Chocolate Chip Popcorn Treats. The sky’s the limit with these flavors!


As part of the Passionate Bloggers program, Duncan Hines sent me a Sweet Treat package with everything I would need to create some fun recipes for you. One of the cake mixes they included was French Vanilla, and on the side of the box is a recipe for a Coconut Bundt Cake. I immediately thought of the Key Lime when I looked at that recipe, because Key Lime and Coconut go hand-in-hand.

Also included in the kit was a Wilton Mini Whoopie Pie Pan. I’ve used my regular sized whoppie pie pan to make deep-dish cookies a few times, so I figured, why not use it for mini cookies? A perfect fit. And, if you don’t have this pan, you can totally use a mini muffin tin. They’re almost the same size!

{But wait – you want the pan, right? And the cute push pop containers? AND all the Duncan Hines loot? Well, guess what? Duncan Hines is giving away the same prize pack I got to one of YOU! Keep reading for more info!}

To make these Coconut Key Lime Pie Cookie Cups, I mixed a coconut cream pudding mix into the French Vanilla Cake Mix to turn it into a coconut cookie. I also added some coconut extract (optional if you don’t have it, I got mine at Walmart, FYI) and shredded coconut for extra coconut oomph. The base isn’t overly sweet and pairs wonderfully with the sweet and tart Key Lime Pie frosting. The cookies are topped with some extra coconut and some graham cracker crumbs, to remind you of an actual Key Lime Pie.

These are really, really good. I ate 5. In one sitting. Then I froze the rest to get them out of my sight. Too bad I know where they’re hidden in the freezer…

Coconut Key Lime Pie Cookie Cups

Yield: 51 cookies

Adapted from the recipe on the side of the Duncan Hines Cake Mix box.


  • 1 box Duncan Hines French Vanilla Cake Mix
  • 1-3.4 ounce box coconut cream pudding mix
  • 2 eggs
  • 1 stick butter, softened
  • 1/2 teaspoon coconut extract, optional
  • 3/4 cup shredded sweetened coconut
  • 1 or 2 cans Frosting Creations Starter Frosting
  • 1 or 2 packets Key Lime Pie Frosting Creations
  • Toasted Coconut and graham cracker crumbs for garnish, optional


  1. Preheat oven to 350 degrees. Spray a mini whoopie pie tin and/or mini muffin tins with cooking spray. (Makes about 50 cookie cups.)
  2. Mix cake mix, pudding mix (dry), eggs, and butter on low speed using an electric mixer. Beat until batter comes together, scraping the sides of the bowl as needed. Stir in coconut extract (optional) and coconut.
  3. Scoop tablespoon sized balls into prepared pans. Press to fit. Bake 7-8 minutes, rotating pans halfway through baking. Cool completely before removing from pans and frosting.
  4. Stir one packet Key Lime Pie Frosting Creations into one can of frosting. You can simply spread the frosting on the cookies with a knife, and top with toasted coconut and a sprinkle of graham cracker crumbs. Or, use a pastry bag fitted with a 1M tip to pipe the frosting onto the cookies. If you are piping the frosting, you may need a second can of frosting. (I like to add lots of frosting!)

  1. I’d love to win the prize package. I am a new follower and I love your photography and fun ideas. Thanks!

  2. I’m excited to try the Key Lime Pie flavor. Thanks for offering the chance to win.

  3. Those mini whoopie pie pans are da bomb! I would love to have one…And, try the DH goodies, too…With our boozy creations, of coure. Bake It With Booze goes Duncon Hines! Yay! Thanks for the giveaway, Dorothy!
    P.S. I did buy a few of the mixins a while back hoping to make something with the cool flavored vodkas that Hayley got me last year. So many recipes, so little time. :)

  4. Oh my gosh, Dorothy. I can’t tell you how many times I’ve gone to grill something and either ran out of propane OR started a gas fire (and destroyed the food) because I forgot to clean the grates one too many time. I realize you’re talking about your oven…but you know, the whole “I am so ready to make this!” and then “Oh crap, I can’t make this!” :*(

    I’d eat at least 5 of them. Probably 10. You’re going to make me fat.

  5. Aw, that stinks about your oven. Glad you were able to hijack your SIL oven so you could make these amazing cookie cups. They look sooo good!
    Jennifer @ Mother Thyme recently posted..Caesar Salad DressingMy Profile

  6. I want to try key lime!

  7. peaches and cream is intriguing!

  8. What a lovely idea Dorothy. These sound delicious!!!
    Aimee @ ShugarySweets recently posted..Lemon Chia Coffee CakeMy Profile

  9. Such a bummer about your oven!! Lucky you have such a great sis in law :)
    These are SO PRETTY! They make me want a vacation….

  10. THIS is a rockin giveaway! I am so sorry to hear about your oven! That happened to a loyal blog reader recently and I can’t even imagine! Hope you’re good as new though now. I have a regular sized whoopie pie pan and a mini sized donut pan, but not a mini whoopie pie or mini muffin pan. They’re adorable and love the flavors. Fave frosting…pink lemonade or key lime!

  11. Pink Lemonade and Fruit Punch sounds great! I’m looking forward to trying them out!
    Your cookie cups are too cute and look yummo!

  12. I would love to win this, the flavor packets are awesome, and to get the ppppppush pops and the mini whoopie pan would be great,

  13. Oooooo…. the Cotton Candy! So fun! :)

    I can feel your pain about the broken oven. That also happened to me a few weekends back & that is when I decided to bake cookie bars in my Crock Pot, lol! ;)

  14. I am addicted to your site! Great giveaways, too!

  15. Christine Redman says:

    Hate when I am hungry and you come up on my newsfeed! I don’t, really. i love it!!!
    love how everything you bake always looks so delish!!! Would love!!

  16. Ugh, my oven has been on the fritz lately, so I totally feel your pain – the repairman estimated the replacement part as nearly as much as a new oven, so yeah…looks like I’ve got appliance shopping ahead of me. :-( Hope yours is fixed soon! I have to admit, key lime is one of my fave flavors, especially as we’re headed into spring-time. These look awesome!
    Ashley @ Kitchen Meets Girl recently posted..Skinny Strawberry MuffinsMy Profile

  17. These are so pretty! Glad things worked out with the oven (for now)!

  18. Key Lime sounds refreshing

  19. I want to try the peaches and cream flavor! Thanks for all the work you do in sharing your blog with us!

  20. What a super cute cookie cup! I am loving that Key Lime flavor packet too!!! I have a big whoopie pie pan…I am feeling the urge to get the small one now! My fingers are crossed!!!

  22. Also, I think I would be most excited to try the Key Lime or Fruit Punch flavors!

  23. I can’t pick just one. Imagine a summer picnic with a cupcake assortment of key lime pie and pink lemonade cupcakes.

  24. Holy Key Lime Pie Batman! These look amazing. Key Lime Pie is my favorite pie of all time…I’m gonna have to make these…SOON!
    Wendy @ AMFT recently posted..Homemade Coffee CreamersMy Profile

  25. Oh….All the limited edition frosting sound delicious. But I’m a big fan for citrus, so I can’t wait to try the pink lemonade. The color is so pretty too! :)

  26. Oh my, living way over here we have Duncan Hines. We can have Devil’s Food Cake Mix or nothing. AND only one chain (Woolworth’s) carries it. I swooned when I saw your photos. Everything here must be made from scratch (other than chocolate cake)

    These look really cute.

  27. Oh my gosh, I don’t know what I do if my oven broke!! Whew, good to know “jiggling” works! These may be the best things I’ve seen since sliced bread-really! I’m loco for key lime!

  28. Stacey B. says:

    Peaches and cream.

  29. Love these!

    Cindy Harris recently posted..Lemon Pie BarsMy Profile

  33. Oh my goodness! A broken oven? That stinks. The jiggling thing cracks me up…how many times do we “fix” things by jiggling or kicking it? LOL. These cookie cups look great by the way!
    Joanne @ Fifteen Spatulas recently posted..Fridge Staples: Cranberry Chicken SaladMy Profile

  34. Gotta go with key lime, all four of us love key lime!

  35. I can totally relate to your kitchen story….. My oven may be in working condition (knock on wood) but my mixer almost died. And while it’s not quite as important as an oven, big time tears would have been shed!!

    These make me think of the lime in the coconut song!! Such a cute idea!!
    Emily {Pink Tiger in the Kitchen} recently posted..chocolate cupcakes w/ mint chip buttercreamMy Profile

  36. I am excited to try the key lime! yummy!

  37. Key Lime is the one I’d like to try because it looks/tastes so springy. This would be a perfect Easter dessert.

  38. Definitely the Key Lime!

  39. Having your oven break is the worst! My computer crashed the other day and Its in the loyal hands of Apple for the next week! An oven and a computer are two things every food blogger needs. I think I am going to drown my sorrows in these cookie cups. Key Lime is my favorite!
    Nicole @ Youngbrokeandhungry recently posted..Roasted Vegetable LasagnaMy Profile

  40. I’m head over heels in love with Key Lime anything!!! And it is the PERFECT partner for coconut. Love your shots of the cookie cups, especially the overhead one – gorgeous!!

  41. A good cookie with yummy icing … fantastic!

  42. I’d love to win the package. Key Lime is my frosting choice and look forward to making the cookie cups. Yummmmm ;)

  43. Definitely the peaches and cream, but pink lemonade is a close second.

  44. These sound delish! Will be making these. I would also love to try the peaches and cream flavor. Yum!

  45. Can’t wait to try this recipe. I love Key Lime and these look so good!

  46. omg i’m so craving sugar cookie with icing right now! If I were to choose, and if Duncan Hines made it, I would totally go for a cookies n’ creme flavored frosting. Sounds amazing right now! lol

  47. I’ve already tried a few, but haven’t had the Cotton Candy yet.

    Melissa recently posted..It’s a…. (Gender Reveal Cupcakes)My Profile

  49. The Key Lime cookie cups are a great idea! Plus, they’re cute! It’s the worst when something in the kitchen breaks – especially the oven! They should make grills with little side ovens (like the side burners) just for these kinds of emergencies! Fingers crossed the “jiggling” holds until the part arrives! Have a great week!

  59. Mama Kim says:

    These sound super yum! Can’t wait to try!

  60. OH MY HEAVENS. These look insanity, Dorothy! I’m so sorry about your oven–isn’t it awful? Did you cry like I did when I saw the repairvan outside my house? Lol, it’s seriously tragic. But thankfully you could crank out this stuff because OMG, it looks AWESOME. Coconut cookie cups with key lime? LOVE.

  61. You had me at key lime. I can not turn down anything key lime flavored.

  62. Laura Jacobson says:

    Oh the Fruit Punch sounds very interesting! Would love to try that!

  63. I need to try these, especially that Key Lime Pie one… heavenly. I’m itching to try the bubblegum one too.

    Thos cookie cups look so good. I’m loving that you guys can flavour your frostings with these goodies. Don’t get them here (which makes me even more eager to try them) so for now I think I might be stuck to buying the oils and see if I can flavour my frosting with those instead.
