What are Peanut Butter Crunch Brownies exactly? The brownie layer is rich, buttery and dense. It is spread with a layer of marshmallow cream then topped with a “crunch” mixture made of peanut butter, chocolate and Cocoa PEBBLES™ cereal.
How to Layer Peanut Butter Crunch Brownies
1. Once you’ve baked your gluten-free brownies, let them cool before adding the toppings.
2. Melt chocolate chips and peanut butter together over medium-low heat.
3. Add Cocoa PEBBLES™ and stir to combine.
4. Top the brownies with a layer of marshmallow creme before adding the peanut butter crunch.
Are Cocoa PEBBLES™ Gluten-Free?
YES! Did you know that all PEBBLES™ Fruity and Cocoa cereals are 100% gluten-free?
You can’t beat the crispy crunchy texture and bold colors of PEBBLES™ cereal. It’s a timeless breakfast classic for a reason! I also love using PEBBLES™ in recipes like these brownies.
I love these brownies because you can make them in advance, and they will stay delicious in the fridge for up to 3 days. Just let the brownies come to room temperature before serving.
Gluten-Free Peanut Butter Crunch Brownies make a great addition to holiday cookie plates, party spreads and more. I hope your family loves this recipe as much as mine does! For another delicious gluten-free brownie, try these Buckeye Brownies.

Sooo good! 10/10 recipe. Came together perfectly.
I’m glad the brownies turned out for you!
So amazing, Erin! We had dinner with an individual who has celiacs disease and I brought these! They were amazing!! The crunch on top gave the perfect balance to the fudgy brownie! It all worked so well together!
I’m so glad you all enjoyed them! Thanks for the comment 🙂
I only made the brownie part, and not the topping but the brownie is delicious and holds together really well. The texture is more like fudge or a flourless torte. So if you prefer a cake-y brownie, as I do, you may be slightly disappointed with the texture. Based on the flour content, I anticipated this going in. I added 1/2 cup unsweetened cocoa to this recipe because I like a really chocolate-y brownie.
Why foil? I usually use parchment paper. I’m assuming the foil helps in the cooking process?
You can use either one! I just like it for ease of clean-up but parchment will do the trick as well.
Hi Erin,
These look amazing! Would it be possible to substitute the eggs for something else, like flax eggs?
Thanks!
K these are soooo rich and delicious, yum! The crunch gives it the perfect texture and I love how gorgeous the layers look.
These are seriously so dreamy! There is nothing like a chocolatey, crunchy, and delicious treat! You won’t believe how easy they are to make.
Would I be able to substitute vegan butter here? My sister cannot have dairy.
Yes that should work! I would probably do half vegan butter half coconut oil though. That would work well with texture/flavor!
