Cookie Butter Brownies with a cookie butter frosting

These Cookie Butter Brownies a combination of my homemade brownie recipe with cookie butter frosting. That’s right. You heard me. COOKIE. BUTTER. FROSTING.

What is Cookie Butter you ask? Imagine peanut butter but instead of the taste of nuts, you have the flavor of Biscoff cookies! So good!

Chewy, soft, thick, chocolaty brownies topped with creamy, heavenly goodness. And, they take no time at all to make! Perfect treats for a party or this weekend.

Main Ingredients Needed

You don’t need much to make these Cookie Butter Brownies. But what you do need is of course, cookie butter! If you can’t find any feel free to sub out with peanut butter, Nutella or another alternative. Here’s what else you need:

For the Brownies

  • Butter + Chocolate – these are used for our fudgy base!
  • Cocoa Powder + Vanilla – both are used for flavor.
  • Sugar – to sweeten.
  • Eggs – for structure and texture.
  • Flour – this fills out the rest of the brownies.
  • Baking Powder + Salt – for rise and to balance out the sweet.

For the Cookie Butter Frosting

  • Butter + Cookie Butter – these two create a super smooth texture as well as flavor. You can find cookie butter at Trader Joe’s or online.
  • Powdered Sugar – to sweeten and thicken the frosting.
  • Vanilla – to flavor.
  • Milk – this thins out the frosting so it’s spreadable.

Make Brownie Batter

Start by melting some butter, chocolate chips and cocoa powder together in a small pot. Once the mixture is all smooth, remove from the heat.

Stir in some sugar, then two eggs, and some vanilla. Measure your dry ingredients out into the pot and stir stir stir until just combined.

Bake + Cool

Pour the batter into a greased 9×9 glass baking dish and bake! Once the brownies are done baking, pull them out of the oven and allow to cool completely.

Cookie Butter Frosting

In the mean time, find yourself a little bit of this stuff: cookie butter! It’s similar to biscoff spread but the trader joes version.

So, take some cookie butter and throw it into a small bowl with some softened butter. Add in some vanilla and powdered sugar and stir.

Once thick paste forms pour in some milk. Stir it all up until your frosting is lovely and smooth. Spread this all over your cooled brownies, cut into bars and serve.

    To prove that I have absolutely no impulse control, I just threw those beautiful brownies in the oven. “But,” I said to my crazy self, “Trader Joe’s is an hour away, I have no Biscoff, and we have a peanut allergy in the house. Can I possibly substitute anything else?” I reached in my pantry and pulled out my Costco-sized container of The Greatest Substance Known to Man (some call it Nutella). Oh yes, I did. And I am not sad about it.

    Will promptly drive five miles out of my way to Trader Joe’s today to get Cookie Butter because those look RIDUNCULOUS, (as my kid would say)!

  3. Emily @ She Makes and Bakes

    Wowzers! I want these right now. We don’t have a Trader Joe’s in Colorado yet (tear), so I’ll be using Biscoff. Delicious!

  4. Hayley @ The Domestic Rebel

    I FINALLY tried Speculoos cookie butter recently, in one of those Trader Joes cookie butter-stuffed dark chocolate bars. Not what I expected, but soo good paired with dark chocolate! I bet these brownies would be just as good!
