Prepare your mini muffin pan with paper liners.

Melt 6 ounces of chocolate chips in the microwave. Stir frequently.

Put a small amount of melted chocolate in the bottom of each muffin liner. Use a spoon or your finger to spread it out to cover the bottom. Or bang the muffin pan on the counter to spread out the chocolate.

Place in freezer for fifteen minutes until chocolate sets.

Mix the peanut butter, butter and powdered sugar with a hand mixer until fluffy.

Remove chocolate from freezer and place a small amount of peanut butter mixture on each chocolate layer.

Melt the rest of the chocolate chips. Spoon more chocolate on the top of the peanut butter mixture. Make sure all of the peanut butter mixture is covered by the chocolate.

Freeze for fifteen minutes to set.

Serve cold or frozen. They tend to melt quickly.
