Low-Carb Peanut Butter Cups
Low-Carb Peanut Butter Cups
Low carb • Sugar-free chocolate shells, peanut butter middle — 15 minutes, twelve cups
These are low-carb peanut butter cups, not candy-aisle cups packed with sugar. A thin sugar-free chocolate shell, a thick peanut-butter middle, and a chocolate lid, like the liners, the bite, and the plate in the photo. Fifteen minutes of work, then a chill. No graham crumbs, no sugar.
Twelve cups. Chill the base before you fill. Keep the chocolate thin.
Why you’ll love these cups
- 4g protein per cup — peanut butter in the middle
- 3g net carbs — sugar-free chocolate and allulose
- About 15 minutes of work, then the fridge
- Dark shell, gold filling, like the bite in the photo
- No boxed mix, no sugar
- They pop out of the liner after a firm chill
Health notes
- Protein: Modest. These are candy cups, not a protein bar.
- Lower carb than store cups: Sugar-free chocolate and unsweetened peanut butter. Close to keto-zero at 3g net.
- Twelve cups: Macros are per cup, not the tray.
- Sweetened peanut butter or sugar chocolate will jump the carbs. Stay with the natural jar.
Key element — thin chocolate, chill, then a firm middle
A thick chocolate base swallows the filling. Melt sugar-free chocolate with coconut oil and coat only the bottom of each liner. Freeze until set. Stir peanut butter with allulose until thick, spoon a dollop in the center, like the photo, then cap. Chill until the lid snaps.
Ingredients
Chocolate (12 cups)
- 8 oz sugar-free dark chocolate
- 2 tsp coconut oil
- 12 paper muffin liners
Filling
- 1/2 cup natural unsweetened peanut butter
- 2 Tbsp powdered allulose
- 1 Tbsp coconut oil, softened
- Pinch of salt
Swaps
- Almond butter: Same 1/2 cup if you want a milder middle.
- Mini liners: Make 18. Count two minis as one serving.
- Sweetened peanut butter or sugar chocolate: Skip them. That is how carbs jump.
Instructions
| 1 | Melt. Melt chocolate with coconut oil until smooth. Set 12 liners in a muffin tin. |
| 2 | Base. Spoon a thin coat into each liner. Freeze 8 minutes until firm. |
| 3 | Fill. Stir peanut butter, allulose, coconut oil, and salt until thick. Spoon a dollop into each cup, like the photo. |
| 4 | Lid. Warm the remaining chocolate. Spoon a thin cap over each filling. |
| 5 | Chill. Freeze 15 to 20 minutes until the lid sets, like the plate in the photo. One cup is one serving. |
Pro tips
- Thin chocolate. A thick shell swallows the peanut butter.
- Chill the base before you fill or the middle melts the chocolate.
- Natural peanut butter. Sweetened jars add sugar.
- Do not overfill. Leave a rim so the lid seals.
- Keep them cold. They soften on a warm counter.
