2 cups pretzels
1 cup Fritos
12 mini peanut butter cups, unwrapped and halved
1 stick unsalted butter (8 T.)
1/2 cup brown sugar
2 cups semi-sweet chocolate chips
Optional: Some peanuts for the top
Preheat oven to 350ºF and line a 13×9 inch pan with parchment paper. Place pretzels in food processor and pulse to break - don't pulverize. Add Fritos to processor and break them up with pretzels. Dump into pan. Unwrap peanut butter cups and throw them in the mix.
Place butter in a non-stick saucepan and melt over medium heat. When butter is melted, stir in brown sugar. Bring mixture to a full boil and boil for 1 minute, stirring once or twice. Pour over Frito mixture and bake for 8 minutes.
Remove pan from oven and sprinkle chocolate chips over hot candy. Return to oven for 1 minute to soften chips. Spread softened chocolate chips over bars (top with chopped peanuts if desired).
Cool at room temperature until you feel the pan is cool enough to be transferred to your refrigerator, then transfer to refrigerator to set the chocolate. When chocolate is set, lift from pan and break up the candy. Store in an airtight container.
