Line cupcake liners into a cupcake/muffin tin. Set aside. If you don't have a tin, you can still make this recipe with your cupcake liners.
Melt the chocolate over bain-marie: Place a saucepan that is large enough to hold a heat-proof bowl over med-high heat. When you put the bowl over the saucepan, it shouldn't touch the simmering water. You should fill the saucepan with 2 inches of (5 cm) water. Once the water simmers, reduce the heat to medium heat, and place the chopped chocolate into the bowl and put the bowl over the saucepan. Stir with a spatula from time to time so the chocolate can melt evenly.
Place one tablespoon of melted chocolate into the liners and spread evenly with the back of a spoon. Let the chocolate set in the freezer for almost 10 minutes.
While the chocolate sets, mix the peanut butter and honey with a spoon. Remove the cupcake tin from the freezer. Add 2 and ½ teaspoons of peanut butter and spread evenly with the back of a spoon through the edges. Slightly press while spreading so the peanut butter layer sticks to the chocolate layer.
Pour 2 teaspoons of melted chocolate over the peanut butter layer, spread with the back of a spoon. Cover with a plastic film and keep in the freezer for almost 10 minutes to let the chocolate set.
If you don’t eat them immediately, keep the peanut butter cups in the fridge. You can store the peanut butter cups in an airtight container in the fridge up to a week or in the freezer up to a month.
