1 pound vanilla almond bark coating
Line a 15 1/2x10 1/2-inch jellyroll pan with non-stick aluminum foil.
Break the almond bark into 1-inch pieces and place in a 1 1/2-quart microwave-safe bowl. Microwave on high for 1 to 2 minutes or until melted. Stir until smooth.
Add the peanut butter and microwave on high for 2 minutes or until melted. Stir again until smooth. Microwave an additional 30 seconds if needed and spread the mixture into the pan.
Melt the chocolate morsels in a 2-cup microwave-safe measuring, cup on high for 1 to 2 minutes. Pour the melted chocolate over the peanut butter mixture and swirl through with a knife.
Cool and break into pieces. Store in an airtight container.
