Melt chocolate chips in the microwave at medium power in 30 second increments and stir until smooth.
Swirl in melted chocolate.
Add pretzels and candy, lightly pressing down to adhere.
Allow to set until solid.
Notes
Use a heat-proof spatula to spread the peanut butter and chocolate layers.
For the chocolate, we use a good quality semisweet chocolate chip because that’s what we tend to have on hand. You can use milk or dark chocolate if you prefer.
Add different candies - M&Ms, Reese's Pieces, different types of chocolate chips, nuts etc.
Instead of pretzels, try graham crackers, nilla wafers, or your favorite salty snack addition.
For faster set-up, you can throw the entire pan into your refrigerator!
