Place 18 cupcake liners in your cupcake tin.
In a large bowl using an electric mixer combine the peanut butter and butter until well mixed.
1 cup peanut butter, ¼ cup butter
Add the vanilla extract and confectioners sugar and mix until well combined. The mixture will be crumbly.
1 teaspoon vanilla extract, 1 ½ cups confectioner's sugar
In a microwave safe bowl melt one of the almond barks in the microwave in 30 second intervals until the chocolate is melted and smooth.
½ pound white almond bark
Spoon a little bit of the chocolate in the bottom of each cupcake liner. Use a spoon to spread the almond bark around the bottom of the cupcake liners and slightly up the sides.
Using half of the peanut butter mixture (save half for the other chocolate), roll about 1-1½ tablespoons the peanut butter mixture into a ball and then flatten it out into a disc.
Place the discs into each chocolate lined cupcake liner.
Spoon more chocolate over the top of each peanut butter disc.
Immediately sprinkle with the festive sprinkles.
Christmas sprinkles
Repeat with the other flavored almond bark.
½ pound chocolate almond bark
Let the peanut butter cups set for an hour at room temperature or 15 minutes in the fridge.
