Indulge in the perfect blend of creamy peanut butter and rich chocolate with these easy-to-make, low-carb peanut butter cups!
Combine the melted coconut oil, peanut butter, vanilla extract, and erythritol in a mixing bowl.
Stir the mixture until everything blends smoothly, forming the peanut butter filling base.
Split the prepared peanut butter mixture in two. Add unsweetened cocoa powder to one half and mix well, creating a chocolatey base.
Set mini cupcake liners on the tray. Fill each cup about a quarter full with the cocoa peanut butter mix, then gently smooth the surface with a spoon.
Place the tray in the freezer for 40-50 minutes for the base to firm up. Once the first layer is solid, take the tray from the freezer.
Fill the cups halfway with the non-cocoa peanut butter mixture.
Put the tray back in the freezer, allowing the peanut butter cups to freeze for 50-60 minutes until firm.
When they're completely frozen, remove the cups from the molds and serve!
