In a microwave-safe bowl, add the chocolate chips. Heat in the microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.
If you want to make your chocolate even more luscious, add the optional 2 teaspoons of oil and stir until fully combined.
Gradually fold in the rice crispies cereal. Start with 1/2 cup and add more if you desire extra crunch.
If you’re using any add-ins like nuts, seeds, or dried fruits, fold them into the mixture now.
Spoon the chocolate-cereal mixture into the silicone muffin cups or lined muffin tin, pressing down gently to pack them in.
Place the filled molds in the refrigerator for about 30 minutes, or until the chocolate has set completely.
Once set, remove the cups from the molds and enjoy your delicious No Bake Chocolate Crunch Cups!
