Gooey Chocolate Peanut Butter Protein Rice Krispie Treats
If a classic Rice Krispie treat and a peanut butter cup had a baby, this would be it.
These chocolate peanut butter crispy cubes are rich, gooey, salty-sweet, and somehow still have protein mixed in without tasting like a “protein recipe.”
The combination of brown butter, melted marshmallows, creamy peanut butter, and Cocoa Krispies creates the kind of treat that disappears almost immediately in our house.
I added BetterDays chocolate protein powder for a little extra staying power, but the texture still stays soft and chewy instead of dry and dense.
Which is where most protein desserts completely fall apart.

Tips
my baking essentials:
The Texture
The best Rice Krispie treats are soft, chewy, and loaded with marshmallow flavor.
Not dry.
Not hard.
Not the kind that rip your teeth out.
The brown butter gives these a deeper almost caramel-like flavor, while the peanut butter helps keep everything rich and creamy.
And unlike a lot of protein desserts, these still feel indulgent.
That’s the goal.
Variations
You could easily switch these up with:
I already want to try a frozen Snickers-inspired version next.
Shop the protein powder
You already know that this is my favorite protein powder out there. I’ve made so many recipes with it and they turn out great every time! Get yours here.
I love a dessert that feels a little nostalgic while still being practical enough to keep around for snacks or quick sweet cravings.
These hit both.
They’re rich, gooey, chocolatey, slightly salty, and fun to eat. The kind of treat you cut “just a little piece” of and somehow keep wandering back into the kitchen for all night.
And if you’re trying to add a little more protein into your day without giving up desserts that actually taste good… these are a pretty solid place to start.
