You’re in for a three layer treat with these Halloween Oreo Brookie Bars. They're soft and chewy with a chocolate chip cookie base, Oreo cookies in the middle and fudgy brownie on top!

Can you believe it’s Halloween already? I feel like this year went flying by! I’ve never been crazy about Halloween but it’s no secret that I’m a sucker for sweets. So I’ll use any excuse and get in the spirit with some seasonal baking and sweet treats.
What is a “Brookie”?
Is it a brownie? Is it a cookie? It’s both! It’s a brookie. Now, you never have to choose again between a fudgy brownie or chocolate cookies. You get the best of both worlds here in one recipe.
If you’ve never heard the term “Brookie” let me explain. It’s when you take cookie dough and brownie batter and bake them together in one recipe, typically in bar form.
What's in this Oreo Brookies Bar?
- Top Layer: almond flour brownie cookie dough
- Center Layer: Halloween Orange Creme Colored Oreo
- Bottom Layer: almond flour cookie dough layer
Typically a brookie only has two layers, the cookie dough and the brownie batter. But I thought, why not take it one step further, in the spirit of Halloween, and sandwich a layer of orange cream filled Halloween Oreo cookies between the layers? It’s the perfect Halloween dessert when you can’t decide between the two… or three.
Ingredients You’ll Need:
To make these bars, you only need a few ingredients:
- Butter
- Light brown sugar
- White sugar
- Egg
- Vanilla extract
- Almond flour
- Unsweetened cocoa powder
- Baking soda
- Sea salt

How to make the Brookie Bars:
The Halloween Oreo Brookie Bars are made completely from scratch, minus the Oreos of course. The cookie dough and brownie mix are both made with almond flour. The best part is, there’s no decorating involved and no special skills needed.
To make the brookies it’s as simple as:
- Mix the batter in a large bowl for the almond flour chip cookie dough and the almond flour brownies.
- In a baking pan, layer the cookie dough on the bottom, then a layer of Ores cookies in the middle and lastly the brownie layer on top.
- Bake them in the oven for about 35 minutes. Then cut them into squares and let the vibrant hint of orange color add a festive touch.
