Nutter Butter Rice Krispie Bars Recipe Made Stepwise

Step 1: Prepare the Baking Dish
Start by greasing a 9×13 inch baking dish with a bit of butter or lining it with parchment paper for easy removal later. This will prevent the bars from sticking and make cleanup a breeze.
Step 2: Melt Butter and Peanut Butter
In a medium saucepan over low heat, combine the butter and peanut butter. Stir continuously until both are melted and fully combined. Be careful not to let it burn.
Step 3: Add Marshmallows
Once the butter and peanut butter are melted, add the mini marshmallows to the saucepan. Stir continuously until the marshmallows are completely melted and the mixture is smooth.
Step 4: Combine with Rice Krispies and Nutter Butter Cookies
In a large mixing bowl, combine the chopped Nutter Butter cookies and Rice Krispie cereal. Pour the melted peanut butter and marshmallow mixture over the dry ingredients. Use a spatula to gently fold everything together until evenly coated.
Step 5: Press into the Baking Dish
Transfer the mixture into the prepared baking dish. Use the back of the spatula or your hands (lightly greased to prevent sticking) to press the mixture evenly into the dish. Make sure it’s packed tightly, so the bars hold their shape when cut.
Step 6: Let It Set
Allow the bars to cool at room temperature for about 30 minutes, or until they are set. For faster results, you can place them in the refrigerator for about 15 minutes.
Step 7: Cut and Serve
Once set, lift the bars out of the baking dish using the edges of the parchment paper (if used). Cut into squares or rectangles, and enjoy!
Spring–Summer–Fall–Winter Ideas

Frequent Missteps to Avoid
- Not pressing the mixture firmly into the baking dish can result in crumbly bars.
- Using too much heat when melting the butter and peanut butter can cause the mixture to burn.
- Forgetting to grease the baking dish or line it with parchment paper can lead to sticking.
- Using stale or old Rice Krispies can affect the texture of the bars.
Shelf Life & Storage
These Nutter Butter Rice Krispie Bars can be stored in an airtight container at room temperature for up to a week. If you want to extend their shelf life, you can refrigerate them, which will keep them fresh for up to two weeks. Just make sure to separate layers with parchment paper to prevent sticking.
Troubleshooting Q&A
Why are my Rice Krispie bars too hard?
If your bars are too hard, it’s likely that you used too much marshmallow or didn’t melt the mixture properly. Make sure to follow the ingredient measurements and melt until just smooth.
Can I use different types of cookies?
Absolutely! While Nutter Butter cookies give a distinct flavor, you can try other cookie varieties like Oreos or chocolate chip cookies for a different twist.
How do I prevent the bars from sticking to the pan?
Greasing the pan thoroughly or using parchment paper will help prevent sticking. If you find they’re still sticking, try using a non-stick spray.
What can I do if my bars crumble when I cut them?
If your bars are crumbling, it’s possible they weren’t packed tightly enough in the pan. Next time, press the mixture down firmly to ensure they hold together better.
