Slutty Brownies

Introduction

Let’s get one thing straight — calling them “slutty” isn’t just for the clickbait. These Gluten-Free Oreo Cookie Slutty Brownies are scandalously indulgent, stacking three desserts into one decadent bite: a chewy cookie base, a gooey brownie layer, and a middle layer of your favorite gluten-free chocolate sandwich cookies. You know the vibe.

This version swaps out regular flour for a gluten-free blend, so you get all the flavor with none of the gluten. Expect rich chocolate, soft centers, crispy edges, and serious crowd-pleasing potential — all done in under an hour.

Top Tips for Perfecting Slutty Brownies

Use Room-Temperature Eggs

This helps your batters mix more evenly and gives you smoother textures.

Chill Before Slicing

This makes for neat, clean cuts and keeps the layers intact.

Use a Scale

For accuracy in gluten-free baking, weight is more consistent than volume.

Add Xanthan Gum if Needed

If your flour blend doesn’t have it, add 1/2 tsp for best texture and structure.

Want Bolder Flavor?

Add 1/2 tsp espresso powder to the brownie mix to intensify the chocolate notes.

Storing and Reheating Tips

  • Fridge: Store in an airtight container for up to 5 days.
  • Freezer: Freeze individual slices for up to 2 months.
  • Reheat: Microwave for 10–15 seconds to revive gooey magic!

FAQs

Can I make these in a food processor or stand mixer?

Absolutely! Just be sure not to overmix the gluten-free batter.

Can I make them by hand?

100%! This recipe is totally approachable with just a bowl and spoon.

Does this recipe need xanthan gum?

Only if your gluten-free flour blend doesn’t already include it.

Can I use other gluten-free flours like coconut or buckwheat?

No — coconut and buckwheat absorb moisture differently. Stick with an all-purpose GF blend.

Can I make this dairy-free too?

Yup! Swap the butter for vegan butter and use dairy-free chocolate chips.

Do I need weighing scales?

Highly recommended for consistent, bakery-quality results
