Loaded Oatmeal Blondies

I’m kind of addicted to blondies. I’m also addicted to oatmeal cookies, so I married the two. Best decision ever!

2 Loaded Oatmeal Blondies recipe stacked on top of each other

Next week we are having laminate wood flooring installed in our entire first floor, including the kitchen. Which means we pretty much have to move out of the main living area for 3 days.

I have to clean out my pantry. I have to clean out my hutch, the bookshelves, the entry hall table. I have to empty my prop cabinet. Oh the horror…

{Actually, I’m going to be in Miami for BlogHer Food starting tomorrow through the weekend. So my husband has to do it. Lucky me, not so lucky him!}

It’s probably a good thing we have to clean everything out – we’ve lived here 2 years and have way too much stuff. I see a garage sale in our very near future.

I started a few weeks ago by cleaning out the pantry. (Who am I kidding? I have to do this every few weeks!) I found several half opened bags of chocolate chips, peanut butter chips, butterscotch chips, coconut, and various candies. Immediately I thought about making a loaded chocolate chip cookie or bar. But I’ve done that already.

When I realized I had butterscotch chips, my first thought was oatmeal. I love, love the combination of oatmeal and butterscotch. Scotcheroos are the best (especially in cheesecake bars…or toffee!)

Then it hit me: an oatmeal blondie.

Sometimes I can be a genius. 😉

These bars are the perfect marriage between oatmeal cookie and blondies. I used my favorite blondie recipe and edited it a bit to also be an oatmeal cookie. They’re filled with brown sugar and old-fashioned oats for a perfectly chewy bar cookie!

Bar cookies are just so much easier to make too – just press them in the pan and bake. No need to chill dough, no need to worry about if they’ll spread too much. And if you’re like me and line the pan with foil, there is almost no clean up. #barcookiesforthewin

The best part about these loaded oatmeal blondies are the mix-ins. You can seriously add whatever you want! Clean out your pantry and throw it all it. You want 2 cups total of add-ins. Here are some ideas:

  • Chocolate chips (white, semi-sweet, or milk)
  • Butterscotch chips
  • Peanut Butter chips
  • Toffee bits
  • M&Ms or Reese’s Pieces
  • Chopped up candy bars like Butterfingers or Reese’s Peanut Butter Cups
  • Coconut
  • Nuts

I used a combination of several of the above. I just poured different candies and chips into my 1 cup measuring cup until it was full – twice. I also topped the bars with some mini M&Ms for color. That’s totally optional, but it makes for pretty pictures. 🙂

What will you add to your loaded oatmeal blondies? I’m going to do peanut butter cups next time…are you surprised?

Since I need to clean out my closets for my floors, I was really hoping to take part in The Great Baking Closet Clean Out today, hosted by Java Cupcake and Make Bake Celebrate. Unfortunately, I couldn’t get my act together in time to actually clean everything out before today. But a bunch of bloggers got together to show you their organizing prowess, and they’re doing a giveaway to the container store! Go check them out!

But first, print this recipe. You’re gonna need it! 🙂

Yield 24 bars
Serving Size


  • 1/2 cup unsalted butter softened
  • 1 1/4 cups packed brown sugar
  • 1 egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1 cup all-purpose flour
  • 1 1/2 cups Old Fashioned Oats
  • 2 cups of mix-ins I used a combination of chocolate chips, M&Ms, coconut, toffee chips, butterscotch chips, and peanut butter chips. Use whatever you have lurking in your pantry. Any combination works!


  • Preheat oven to 350°F. Line a 9x13” pan with foil and spray with cooking spray. (Foil is optional; I like using it for easy removal.)
  • Cream brown sugar and butter in the bowl of an electric mixer fitted with a paddle attachment. Add eggs and vanilla and beat until combined. Mix in salt, baking soda, and cinnamon. Add flour and mix until combined. Stir in oats. Stir in your mix-ins.
  • Press into prepared pan (dough is sticky, spray your hands with cooking spray to avoid it sticking to your hands). If you want, you can sprinkle a few more of your mix-ins on the top to make them look prettier (as I did with the mini M&Ms in the pictures).
  • Bake for about 25 minutes. (Be careful not to overcook - the center will still be jiggly when you take these out of the oven and they will finish cooking and firming up as they cool.) Cool completely before slicing into squares.

  1. Oh my goodness! You timed that well. I’ll have to remember that for next time. Plan to have the housework done while I’m away. Brilliant!
    So are these bars. They look like you eat them in pairs. I could never eat just one!
    Hope you enjoy your time at the conference. Wish I could be there!

  2. All the oatmeal make them super healthy, right??!? Haha! Love oatmeal bars like this, these look awesome!

  3. I love oatmeal blondes. I’m a huge fan of oats and try to add them into everything. These bars look delicious!
    Ah, and perfect timing for the Blogher and not having to move all that stuff. 😀

  4. Ya, I could eat the whole batch. And yes I could clean out my baking cupboards out way more often than I do… #oops!

  5. I love recipes like these where you can just throw in any extras you have! Plus I mean…oatmeal blondies=YUM!

  6. I hope you keep cleaning if that means you make delicious babies like these. Be sure to take before and after pictures. We put laminate floors in upstairs and love them. Dog proof!

  7. I think I would be scared to have someone else clean out my pantries … like, I’m pretty sure half of it is teetering on the expiration date or would be considered extra (aka three spoons, a dozen straws …) Can’t wait to hear about blogher! And if you have extras of these bars you need help with, you know , while you are gone, I’m here 😉

  8. These look like the perfect oatmeal blondies! Love the awesome flavors they’re loaded with! Pinned!
