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.

For full details on how to make Cookie Butter Brownies, see the recipe card down below 🙂

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.

    Hi! Lovely recipe, I’ve a tub of Speculoos (caramel biscuit) spread at home and I’m dying to use it in a recipe!

    Just one question, may I bake the brownie in a metal square pan? Or does it have to be glass? Thanks very much!

    Wow, these are amazing. Thanks so much for the great recipe and directions. These were the best brownies I have had. Thanks for the introduction to cookie butter (LOVE). Since the cookie butter is miked with milk and butter in the frosting do you have to refrigerate these brownies?

    Just made these, only had an 8×8 pan but they look good, in fact I don’t think I would want them any thinner. Would make double the frosting next time, half for the brownies, half for me to scrape right out of the bowl with my fingers :-p

    Oh my goodness!! You crack me up! SO my humor and I was laughing out loud because I do this with my husband, too! Can’t wait to make these delicious looking brownies! After my other pan of frosted brownies are gone…can you tell I love brownies? 🙂

    This sounds so scrumptous! But I guess I’ll never know how they taste since I have no idea what biscoff is and there are no Trader Joes in Wheeling, WV. to buy cookie butter! I’ll just have to dream about the taste!
