The Ultimate Keto Indulgence: Jumbo Peanut Butter Cups

Is there a more iconic duo than rich chocolate and creamy peanut butter? It’s a classic combination that truly feels like a dream, especially when you’re following a keto lifestyle. Get ready to meet your new favorite indulgence: Keto Jumbo Peanut Butter Cups. And when I say jumbo, I mean it. These are seriously decadent, generously-sized treats designed to satisfy the most intense cravings. One bite and you’ll be hooked! If you prefer a more modest portion, this recipe easily adapts to a mini muffin pan for a bite-sized version.

Ingredients

• 2 cups / 340g sugar-free dark chocolate chips
• ¼ cup / 56g coconut oil
• ¾ cup / 190g reduced-sugar creamy peanut butter
• Special Equipment
• 12-well standard-sized silicone muffin pan, or 12 silicone or paper muffin liners

Instructions

1. Directions
2. Prepare your pan. Place a 12-well silicone muffin pan or 12 individual silicone/paper liners on a small baking sheet for stability.
3. Melt the chocolate. In a microwave-safe bowl, combine the chocolate chips and coconut oil. Microwave at 50% power in 30-second intervals, stirring between each, until fully melted and smooth. Let it cool slightly.
4. Create the base layer. Pour approximately 1½ tablespoons of the melted chocolate into the bottom of each muffin well, creating an even base. Transfer the baking sheet to the refrigerator until the chocolate is completely firm.
5. Add the peanut butter filling. Once the chocolate base has hardened, remove the pan from the fridge. Spoon 1 tablespoon of peanut butter into the center of each cup, leaving a small border around the edge.
6. Add the top layer. Gently pour the remaining 1½ tablespoons of melted chocolate over the peanut butter in each well, ensuring the filling is completely covered. You may need to briefly reheat the chocolate if it has started to set.
7. Chill until firm. Return the baking sheet to the refrigerator and chill until the peanut butter cups are completely solid. Store in an airtight container in the refrigerator for up to 3 weeks.
