Ingredients You’ll Need
-
1 cup sugar-free chocolate chips — because keto dessert should still taste like actual dessert.
-
2 tbsp coconut oil — keeps the chocolate glossy and smooth like a fancy candy shop.
-
1/2 cup natural creamy peanut butter — the star of this delicious little operation.
-
2 tbsp powdered erythritol — sweetness without the sugar-fueled emotional damage.
-
1 tsp vanilla extract — tiny amount, dramatic personality.
-
Pinch of sea salt — somehow makes everything taste expensive.
-
Optional crushed peanuts — crunchy chaos for texture lovers.
Step-by-Step Instructions
-
Melt the chocolate mixture.
Add the chocolate chips and coconut oil to a microwave-safe bowl. Microwave in 20-second bursts, stirring each time until smooth and glossy. Don’t overheat the chocolate unless gritty sadness sounds appealing. -
Build the chocolate base.
Line a muffin tray or silicone molds with cupcake liners. Spoon a thin layer of melted chocolate into each cup and spread evenly across the bottom. Freeze for about 10 minutes until firm. -
Make the peanut butter filling.
Mix the peanut butter, powdered erythritol, vanilla extract, and sea salt in a bowl. Stir until creamy and smooth. Resist eating the entire filling with a spoon like a tiny peanut butter goblin. -
Add the filling layer.
Drop spoonfuls of peanut butter filling onto the chilled chocolate bases. Flatten gently with the back of a spoon so the tops stay even. Keep the filling centered unless crooked peanut butter cups spark joy for you. -
Cover everything with chocolate.
Pour the remaining melted chocolate over the filling until fully covered. Sprinkle crushed peanuts on top if you want extra crunch and dramatic dessert flair. -
Chill and immediately lose self-control.
Freeze the peanut butter cups for 20–30 minutes until firm. Peel off the liners and try very hard not to eat three while standing directly in front of the freezer.
Common Mistakes to Avoid
-
Burning the chocolate because patience suddenly disappeared.
-
Using peanut butter loaded with hidden sugar sneak attacks.
-
Overfilling the cups and creating dessert landslides.

Leaving them in a warm kitchen until they transform into chocolate soup.
Alternatives & Substitutions
-

-
Add cinnamon for a warm flavor twist that feels oddly sophisticated.
-
Use dark sugar-free chocolate if you like your desserts rich and dramatic.
