Keto Peanut Butter Cups
These easy, no-bake keto peanut butter cups feature a rich, snappy chocolate shell and an ultra-creamy peanut butter filling that won't turn gritty.
Equipment
- Heatproof bowl
- Silicone candy molds
- Small spoon
- Microwave-safe bowl
Ingredients
Chocolate Coating
- 6 ounces sugar free dark chocolate (chopped)
- 1/2 ounce cocoa butter (or 2 tsp coconut oil)
Peanut Butter Filling
- 1/2 cup peanut butter
- 2 tbsp butter
- 1/4 cup powdered Swerve Sweetener
- 1/2 tsp vanilla extract
Instructions
- Melt the chopped chocolate with the cocoa butter in a heatproof bowl over barely simmering water, stirring until fully combined. The mixture should look smooth and glossy, with no thick lumps or dull streaks.
- Spoon a little more than half of the melted chocolate into the candy molds and use the back of a small spoon to coat the bottoms and sides. A thin, even shell works best, and freezing it for 10 minutes keeps the filling from blending into the chocolate.
- Heat the peanut butter and butter in a microwave-safe bowl in 30 second bursts on high, stirring between each burst until melted. Once you whisk in the powdered sweetener and vanilla, the filling should look thicker, creamier, and more uniform.
- Take the chilled chocolate shells out of the freezer and spoon in the peanut butter mixture, stopping just below the top edge. Leave enough room for the final chocolate layer, then return the molds to the freezer for about 10 minutes so the layers stay distinct.
- Warm the remaining chocolate gently if needed, then spread it over each filled cup and seal it to the sides. Chill for 20 minutes, or until the tops are completely firm to the touch.
Notes
Smooth Filling Tip: To avoid a gritty texture, use a powdered or liquid keto-friendly sweetener. Granular sweeteners can make the filling feel sandy. Chocolate Tip: For a shinier shell with a better snap, use cocoa butter. Coconut oil is a good substitute that also helps thin the chocolate for easier coating. Storage: Keep the finished cups in an airtight container in the refrigerator or freezer. They will soften at room temperature, so they must be stored cold to stay firm. Handling Runny Peanut Butter: If using a natural peanut butter that is oily, stir the jar thoroughly before measuring or use the thicker part from the bottom. If the filling still seems too loose, mix in a little coconut flour to help it firm up. Nutrition information is an estimate based on common ingredients and serving sizes.
