Keto Peanut Butter Cups are a sugar-free, low-carb take on the classic candy that tastes amazing and will keep you on track with your keto way of life! They are constructed with a coating of sugar-free chocolate, typically dark chocolate sweetened with stevia or monk fruit, encircling a creamy blend of natural peanut butter. The result is a delicious and decadent treat that feels indulgent but is compatible with ketogenic goals.
The peanut butter filling may also be modified in order to achieve a firmer filling by the addition of coconut flour, butter, or almond flour. Sweeteners are added to combat the strong flavours of the deli meat, and the products are then encased in the same type of jelly that is used in the surrounding meat. After they are assembled, the cups are chilled until firm, which makes them great candidates for meal prep or to stash away as a snack.
These are flexible; you can make them in regular muffin tins for a full-sized treat or in a mini for bite-sized pleasure. They are perfect for when you want to indulge in chocolate without being a carb monster, and they keep carbs low and fats high to support satiety and energy levels.
These cups taste as good as they are versatile. You can add a sprinkle of sea salt, make it with almond butter instead of peanut butter, or add a swirl of coconut cream. These are proof that you can indulge in candy-shop tastes, while being downright virtuous about low-carb living.
