Why You’ll Love Brownie Batter Krispie Treats
This recipe elevates a familiar favorite by adding brownie batter flavor and pieces of real brownies throughout. It’s a quick, no-bake dessert that’s both easy to make and memorable to serve.
- No bake: The base is classic Rice Krispie treats with added brownie mix, so no oven is required.

- Great texture and flavor: Chewy marshmallows, crunchy cereal, and chunks of fudgy brownies make each bite interesting and satisfying.

How to Make Brownie Batter Krispie Treats
If you’ve made Rice Krispie treats before, this is just as simple with a couple of extra steps for brownie flavor. You’ll need a box of dry brownie mix and some baked brownie pieces to stir in.
- Stir 1 cup of dry brownie mix into the melted marshmallow and butter mixture to infuse the brownie batter flavor throughout the treats.

Tip: If you want more chocolate intensity, use cocoa-flavored rice cereal, but note it shifts the flavor away from “brownie batter” toward a more general chocolate taste.
Cut or crumble 2 cups of baked brownie pieces and fold them into the cereal mixture. Premade brownies work perfectly if you don’t have leftovers—this step is forgiving and adds delightful pockets of fudgy texture.
Combine the cereal and brownie pieces with the marshmallow-brownie mixture, press evenly into a lined 9×9 pan, and allow to cool before slicing into bars.

How to Store Rice Krispie Treats
- If preparing ahead, leave the uncut slab in the lined pan and cover it airtight until you’re ready to serve.
- Once cut, keep the bars covered as much as possible; exposed treats will firm up and dry out over time.
- Store cut bars in an airtight container or zip-top bag for up to 2–3 days. They are best within the first day for optimal chewiness.
