How to Make Peanut Butter Bars with Rice Krispies
Get that stove top pan out because we’re heating it up to make melt together the sugars to get that smooth texture we’re looking for in contrast to the crispy Rice Krispies.
- Prep: Line a 8×8 square or 11×7 rectangular baking pan with parchment paper.

- Topping: In a small sauce pan melt the butter and brown sugar. Remove from heat. Add the vanilla, milk and powder sugar and beat until smooth. Spread over the top of the base layer.
- Serve: Chill and then cut into small squares.

Tips
Sift the powdered sugar. Just do it. I didn’t, and no matter how hard you beat the topping you will still have little tiny lumps. Still tastes good, just not as pretty.
Pan size can be different. If you don’t have a smaller baking pan, no worries. Just line the pan with the parchment paper making it the size you need.
Chill before serving. You will want to fully chill these before you cut into them. Once ready to serve, lift the peanut butter bars out of the pan using the parchment paper. Carefully cut using a large knife.
Storage: Store in an airtight container with layer separated by wax paper for up to 3 days at room temperature. Freeze to enjoy later at any time.
