These bars are quite rich and decadent. Cut into 25 squares if serving at a potluck or large gathering, or into 16 squares if you're in the mood for a bigger treat.
- 4 cups (160 g) salted mini pretzels, plus additional for the top
- 1/2 cup (4 ounces) unsalted butter, melted
- 3 tablespoons sugar
- 1 (14-ounce) can sweetened condensed milk (397g), divided
- 1/4 cup (57g) smooth peanut butter
- 3/4 cups (100g) peanut butter chips
- 1/2 cup (100g) mini chocolate chips
- 1 1/2 cups (75g) unsweetened coconut flakes
1 Prep for baking: Preheat the oven to 350°F. Spray or grease an 8x8-inch square baking pan and line the bottom and two sides with parchment paper.
2 Make the crust: Add the pretzels to the bowl of a food processor and pulse until most of the pretzels are fine crumbs with a few larger bits (no larger than the size of a pea). You can also crush the pretzels in a bag with a rolling pin.
Pulse in the butter and sugar (or stir together in a bowl). It should hold together when pressed together with your palm but it’s sandier than a graham cracker crust.
Press the pretzel mixture into the bottom of the prepared pan. Use the bottom of a measuring cup or glass to really compact the mixture.
3 Bake the crust for 15 minutes. Remove and place on a rack to cool slightly.
4 Warm the peanut butter: Measure out 4 tablespoons of the condensed milk into a bowl and set to the side to use later. In a 2-cup measuring glass, combine the peanut butter and remaining condensed milk and microwave for 30 seconds. Stir the mixture until smooth.
5 Assemble the layers: Spread half of the coconut onto the pretzel crust, followed by half of the peanut butter chips and chocolate chips.
Pour the peanut butter and condensed milk mixture over the top and repeat the layers of coconut and chips. Arrange a few whole pretzels on top and drizzle with the reserved condensed milk.
6 Bake the bars: Bake on the center rack of the oven for 35 to 40 minutes or until the edges are just golden around the edges.
7 Cool and store: Remove from the oven and cool completely on a rack before cutting. Lift the block of bars from the pan using the parchment paper, and then use a serrated knife to slice into 16 large bars or 25 bite-sized bars.
Magic bars will keep at room temperature for up to 5 days.
