Keto Big Peanut Butter Cups

These keto big peanut butter cups are a no-bake dessert that tastes better than the store-bought candy, made oversized in a 12-cup silicone muffin pan. The filling is soft and creamy, almost like a mousse. Made with whipped butter and chocolate peanut butter protein powder. Give the layers a full 10 minutes in the freezer each time so the chocolate sets clean before you pop them out.
