I love marrying desserts and today is a super special wedding! Funfetti Cookies and Fudge are now married into one treat: a Funfetti Cookie Fudge Bar, a sugar cookie bar filled with confetti sprinkles and cake batter flavor topped with chocolate fudge!

So, February is kind of a ridiculous month around our house. It’s the shortest month, and Valentine’s Day is right smack dab in the middle. But that’s not all.

My mom’s birthday was last Saturday. Jordan’s birthday is Wednesday. And it’s my Mother-in-law’s birthday month too!

{Why does that always happen in families; the birthday groupings? It’s like you’re attracted to partners whose parents all had really good months several years back, am I right?}

I posted turtles for my mom’s birthday (they’re her favorite) and if you know anything about Jordan you’ll know what’s coming over the next few days. (I’m not telling, come back Tuesday and Wednesday to find out!)

My MIL? Loves fudge. She really, really loves it. I have so much fun every holiday making her new flavors, although she’s told me that I can no longer bring her a whole batch, just a few pieces or she’ll eat it all.

Better her than me, ha. {Kidding!}

I wasn’t able to celebrate her birthday with her this year since I was out of town, but Jordan and Mel went up to visit and took along a box of these Funfetti Cookie Fudge Bars to celebrate. They’re my new favorite food baby!

Last week I made Oreo Truffle Chocolate Chip Cookie Bars and today I’m combining funfetti cookies and fudge.

Sometimes I really, really make myself happy.

I think I’m addicted to funfetti. Is that a thing? I think as I get older my tastebuds get younger. Give me the taste of funfetti birthday cake any day, and I’ll be a happy girl.

The bar cookie base for these fudge bars is made of a from-scratch funfetti cookie. As much as I love cake mix, I love creating funfetti flavor without it. You just need sprinkles and one little secret ingredient: butter extract. Just a little bit added into the batter gives a distinct cake flavor to pretty much anything. Throw in some sprinkles and you’ve got funfetti.

Once the bars cool, you make some fudge for the top. You can do really any flavor you want, but I went with chocolate because I love chocolate frosting on yellow cake. I think the flavors go really well together.

I used an easy fudge recipe, which is pretty much the basis of all my fudges. Chocolate chips + sweetened condensed milk = Fudge. I made a half batch for these bars because the fudge would have been too thick had I not.

Add some sprinkles on top and you have the perfect birthday cookie cake for anyone who loves fudge, cookies, cake, or sprinkles.

And I think that pretty much covers the entire population. Except maybe my husband. (Seriously, how did he come from his mom?)

These were really addicting. I dare you to stop eating at one piece.

My MIL loved them, and I hope you do too!

Happy {belated} birthday Lorna! xoxo

Funfetti Cookie Fudge Bar, a sugar cookie bar filled with confetti sprinkles and cake batter flavor topped with chocolate fudge!
Yield 36


  • 1/2 cup unsalted butter softened
  • 1/2 cup granulated sugar
  • 1 large egg
  • 2 1/2 teaspoons vanilla extract divided
  • 1/2 teaspoon butter extract
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon cream of tartar
  • 1/2 teaspoon salt
  • 2 cups flour
  • 1/3 cup sprinkles plus more for the top
  • 1 1/2 cups milk or semi-sweet chocolate chips
  • 1/2 can fat-free sweetened condensed milk about 5 ounces (just over 1/2 cup)


  • Preheat oven to 350°F. Spray a 9x9” pan with cooking spray or line with foil and spray for easy removal and clean-up.
  • Cream butter and sugar with a hand or a stand mixer. Mix in egg, 2 teaspoons vanilla, and butter extract. Add baking soda, salt, cream of tartar and mix until combined. Slowly mix in flour and beat until smooth. Be careful not to over mix. Stir in 1/3 cup sprinkles.
  • Press batter into prepared pan. If it’s too sticky to handle, spray your hands with cooking spray.
  • Bake for about 17-22 minutes until the top just starts to get golden brown. (My bars to 18 minutes.) Cool completely before continuing.
  • Once bars are cool, add chocolate chips and sweetened condensed milk to a medium saucepan. Heat over low heat, stirring constantly, until melted and smooth. Remove from heat and stir in 1/2 teaspoon vanilla extract. Quickly pour and spread over cooled cookie bars. Quickly sprinkle more sprinkles on top and press lightly to adhere them to the surface. Let come to room temperature, then chill until set. Cut into squares.

  1. This looks delicious, not to mention pretty easy to make! I love funfetti things! I don’t know why, but sprinkles in batter remind me of childhood 🙂

  2. These fudge bars look amazing Dorothy! Perfect for celebrating birthdays – October is that month for me. Love funfetti, fudge and cookies so marrying these all together is simply perfect!

  3. Oh my goodness! These look scrumptious. And so fun– I’ll have to make these for my roommates, they will LOVE them! Thanks, Dorothy!

  4. Your February sounds like my families September 🙂 Beautiful, beautiful desserts. I love the idea of two desserts “marrying” each other; I like funfetti more now as an adult than when I was a kid. Go figure.

  5. I am pretty sure my taste buds are doing the same – growing younger as I’m getting older :). I have been on a funfetti kick myself and am loving it! Needless to say, these bars have my name written all over them. Fabulous!
