Let's start with the Reese's Peanut Butter White Chocolate Bark. I found this recipe on Sally's Baking Addiction. It's very easy to make and goes together quickly.
1 cup creamy peanut butter
1 cup powdered sugar
1/4 cup butter, softened to room temperature
1/2 tsp vanilla extract
1/4 tsp salt
16 oz white almond bark
1/2 cup Reese's Pieces candies
1/4 cup peanut butter chips
Line a 9x13" pan with parchment paper and set aside.
In a ziplock bag, crush the Reese's Pieces and peanut butter chips with a rolling pin and set aside.
In a large bowl, stir together the peanut butter, powdered sugar, butter, vanilla and salt until smooth and creamy. Set aside.
In another bowl set over a bowl of simmering hot water, melt the white almond bark until melted and smooth. Pour half into the parchment-lined pan and spread out evenly. Chill for a few minutes until set. Spoon the peanut butter mixture over the bark layer and spread evenly. Pour the remaining white bark over on top and spread evenly. Sprinkle with the crushed candies and peanut butter chips. If desired, if you have any leftover melted bark, drizzle over on top of the candies. Chill until set and cut up into pieces.
