Ingredients You’ll Need
-
1 cup sugar-free chocolate chips — because keto people still deserve happiness.
-
2 tbsp coconut oil — the silky magic potion.
-
1/2 cup natural peanut butter — creamy, dreamy, slightly dangerous.
-
2 tbsp powdered erythritol — sweet without the sugar crash drama.
-
1 tsp vanilla extract — tiny splash, huge personality.
-
Pinch of sea salt — makes everything taste suspiciously gourmet.
Step-by-Step Instructions
-
Melt the chocolate mixture.
Add the chocolate chips and coconut oil to a microwave-safe bowl. Microwave in short 20-second bursts, stirring between each round until smooth. Chocolate burns faster than your patience on a Monday morning, so don’t rush it. -
Create the chocolate base.
Line a muffin tray or silicone molds with paper liners. Spoon a thin layer of melted chocolate into each cup and spread it around slightly. Freeze them 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 enough to make you question whether you even need the chocolate part anymore. -
Add the filling layer.
Place small spoonfuls of peanut butter filling onto the chilled chocolate bases. Flatten them gently so the tops stay even. Don’t overstuff unless you want peanut butter escaping like lava. -
Cover with more chocolate.
Pour the remaining melted chocolate over the filling until fully covered. Tap the tray lightly on the counter to smooth the tops and remove air bubbles like a fancy dessert chef. -
Chill and enjoy.
Freeze the peanut butter cups for 20–30 minutes until fully set. Peel off the liners and try not to immediately eat three standing in front of the freezer.
Common Mistakes to Avoid
-
Burning the chocolate because you “just needed 10 more seconds.”
-
Using chunky peanut butter if you hate surprise crunch attacks.
-
Forgetting the salt and wondering why the flavor feels flat.
-
Overfilling the cups and creating chocolate-peanut butter explosions.
-
Leaving them in a hot kitchen where they melt into delicious sadness.
Alternatives & Substitutions
-
Swap peanut butter for almond butter if you want extra nuttiness and extra grocery expenses.
-
Use monk fruit sweetener instead of erythritol if that’s your keto soulmate.
-
Add crushed peanuts for crunch because texture matters.
-
Toss in a little cinnamon if you enjoy chaos in a good way.
-
Use dark sugar-free chocolate for a richer, more dramatic dessert vibe.
