Nutter Butter Rice Krispie Bars Recipe Cooking Guide
Step 1: Prepare Your Baking Dish
Start by lining a 9×13-inch baking dish with parchment paper for easy removal of the bars later. This step is optional but highly recommended for a cleaner finish.
Step 2: Melt Butter and Marshmallows
In a medium saucepan over low heat, melt the butter. Once melted, add the mini marshmallows, stirring continuously until they are completely melted and smooth. This should take about 5 minutes. Be careful not to let the mixture boil.
Step 3: Mix in Peanut Butter
Remove the saucepan from the heat and stir in the peanut butter until fully combined and smooth. The mixture should be creamy and consistent.
Step 4: Combine Rice Krispies and Nutter Butter
In a large mixing bowl, combine the Rice Krispie cereal and the chopped Nutter Butter cookies. Pour the melted marshmallow and peanut butter mixture over the cereal and cookies, and use a spatula or wooden spoon to gently fold everything together until all the dry ingredients are coated.
Step 5: Press into Baking Dish
Transfer the mixture to the prepared baking dish. Using a spatula or your hands (lightly greased to prevent sticking), press the mixture down firmly and evenly into the dish. Make sure to pack it tightly for the best texture.
Step 6: Allow to Set
Let the bars cool at room temperature for about 30 minutes to an hour, or until they are set. You can also place them in the refrigerator to speed up the process.
Step 7: Cut and Serve
Once set, lift the bars out of the dish using the parchment paper. Cut them into squares or rectangles, and enjoy! These bars can be stored in an airtight container for up to a week, but I bet they won’t last that long!
Holiday-Friendly Variations
- Chocolate Drizzle: Melt some semi-sweet chocolate and drizzle it over the top of the bars for an extra layer of flavor.
- Sprinkles: Add festive sprinkles on top before the chocolate sets for a fun, colorful touch.
- Nut Toppings: Sprinkle chopped peanuts or walnuts on top for added crunch and flavor.
- Seasonal Flavors: Mix in some cinnamon or pumpkin spice for a fall-inspired twist.

How to Store & Reheat
To keep your Nutter Butter Rice Krispie Bars fresh, store them in an airtight container at room temperature. They will stay fresh for up to a week. If you’d like to enjoy them warm, simply pop them in the microwave for about 10-15 seconds to soften them slightly before serving. However, be cautious not to overheat them, as this can change their texture.
Troubleshooting Q&A
What if my bars are too sticky?
If your bars turn out too sticky, it may be because you used too many marshmallows or didn’t let them cool long enough. Next time, try reducing the marshmallows slightly or allowing them to set longer before cutting.
Why did my bars crumble when I cut them?
Crumbly bars typically result from not packing the mixture tightly enough in the baking dish. Be sure to press down firmly when spreading the mixture to ensure they hold together nicely.
Can I use different types of cereal?
Absolutely! While Rice Krispies are traditional, you can substitute them with other crispy cereals like Corn Pops or even a gluten-free cereal for a different flavor and texture.
How can I make these bars chocolatey?
For a chocolatey twist, you can mix in mini chocolate chips with the Rice Krispies and Nutter Butter cookies. Alternatively, drizzle melted chocolate over the top once they’ve set!
