Ingredients for Halloween Oreo Protein Brownies

These Halloween Oreo Protein Brownies are made simple ingredients you might have in your pantry already – or just easy to access..

Whey-casein Chocolate Protein Powder needed for high protein brownie; I used whey-casein Chocolate flavor from Quest Nutrition.
This and also replaces most of the ‘sugar’.
Whey Chocolate Protein Powder; Dymatize ISO is the one I recommend here.
Unflavored Protein Powder – Quest Nutrition Multi-purpose here. It replaces some of the flour (and carbs) in the recipe for a slightly lower carb higher protein Oreo brownie
Unsweetened Cocoa Powder, or Raw Cacao Powder
Whole Wheat Pastry Flour – or a regular all purpose flour
Some Stevia Sweetener

Non-fat Greek Yogurt – this makes the brownies fudgy and is why we don’t need as any butter.
Almond Milk or regular milk
Baking Soda and Baking Power
Vanilla Extract
Runny Almond Butter or Cashew Butter (no butter or oil to keep this recipe low fat)
I recommend American Dream Nut Butter Pumpkin Cheesecake Almond Butter; Its lower fat and higher protein. The link gives you a discount too.

Halloween Oreos!

How to make Halloween Oreo Brownies with Protein Powder?

This recipe for protein powder Halloween Oreo brownies is extremely easy to make. Just mix the batter, and bake the brownies (with Oreo as stuffing).

Preheat your oven to 350°F and line a baking pan (about 8”) with parchment paper.

Whisk all the dry ingredients in bowl – chocolate protein powders, unflavored protein powder, cocoa powder, flour, stevia, baking soda, baking powder.

Whisk the wet ingredients in a large bowl – yogurt, milk, vanilla, almond butter.

Add the dry mix to the wet and gently fold to combine. Just be gentle and don’t over-mix the batter. The protein powder will make it too dense.
You should have a thick batter. (Taste batter and add stevia powder if you want it sweeter)

Assemble the Oreo Stuffed Halloween Brownies

Transfer the ½ brownie batter into pan, spread.
Place 12 Oreos (see image below) in the middle.
Pour remainging ½ batter on top. Spread evenly.
Bake for about 25 minutes.
tester (toothpick or thin sharp knife) comes out mostly dry.

Tips for Perfect Halloween Oreo Stuffed Brownies Recipe

Use room temperature milk and yogurt;
This is so the wet ingredients and dry ingredients can mix well.

Use Creamy Almond Butter also so that it mixes well into the protein brownie batter.

Don’t over-mix the batter!
Make sure you gently fold the dry mix into the wet to combine them.
If you over-mix it, the protein powder and will make the brownies tough, dense and gummy.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter so you have no extra sugar in this Halloween brownie recipe.

Don’t over-bake the brownies or they might get tough; Remove when the tester/knife comes out mostly dry.
Underbaking a little is okay.

How to store healthy Halloween brownies?

To freeze, individually wrap Hallowen Oreo stuffed brownie pieces in plastic wrap and place in freezer-safe zipper bags or air tight container; They should keep for 2-3 months.
