Simple Ingredients, Real Results
To make these delicious treats, here’s what you’ll need:
- 1/2 cup Peanut butter
- 1/4 cup sugar free powdered sweetener
- 9 ounce Sugar free Chocolate Chips
These ingredients are straightforward and easy to find. Peanut butter is a staple in many kitchens, and using sugar-free sweeteners means you can indulge without compromising your low-carb goals. If you ever run out of powdered sweetener, you can use granulated low-carb sweetener and pulse it in a blender to create your own powder. Simple adjustments can make life easier and more enjoyable.
Step-by-Step Directions
- Start by lining a 9×13 cupcake tin with liners. Don’t forget to spray the inside with cooking spray to prevent sticking.
- Melt half of your chocolate chips in a microwave-safe bowl for about 1 minute. Check the consistency and stir until smooth.
- Spoon the melted chocolate evenly into the 12 cupcake liners. Place the tin in the fridge to harden for about 10 minutes.
- While the chocolate hardens, mix the peanut butter and powdered sweetener in a small bowl. If it’s too thick, microwave for 30 seconds to make it easier to spread.
- Once the chocolate has hardened, add a layer of the peanut butter mixture on top of the chocolate in each liner.
- Melt the remaining chocolate and spoon it on top of the peanut butter layer.
- Chill again for another 10 minutes until set. Once hardened, they are ready to serve!
Serving Peanut Butter Cups
After chilling, the moment of joy arrives when you can finally take your first bite. The contrast between the smooth chocolate and creamy peanut butter creates a satisfying mouthfeel that is both indulgent and comforting. These Peanut Butter Cups are ideal for snacking or sharing during get-togethers. It’s also fun to pair them with a cup of tea or coffee for a treat that feels just a bit more special.

Storing and Reheating
These Peanut Butter Cups can be conveniently stored in an airtight container in the refrigerator. They maintain their texture well thanks to the chocolate and nut butter, and they can last for about a week. Just be aware that the chocolate might become slightly firmer when chilled, but the taste remains delectable. If you prefer them softer, you can let them sit at room temperature a few minutes before enjoying them.
Helpful Notes
Here are a few tips I’ve learned from making these Peanut Butter Cups:
- If you’re looking for a nut-free option, consider using sunflower seed butter as a substitute for peanut butter.
- Keep an eye on the chocolate while melting; every microwave is different, and it’s best to go at shorter intervals to prevent burning.
- Customize the sweetness according to your taste. This can be particularly enjoyable if you’re sharing with family and friends who may prefer different levels of sweetness.
- If you’re after more nutritional protein, try adding a scoop of protein powder to the peanut butter mixture. This converts the treat into a protein booster while keeping it low in carbs.
Easy Variations
Feeling creative? Here are some ways to shake things up with these Peanut Butter Cups:
- Nutty Additions: Incorporate chopped nuts into the peanut butter layer for extra crunch.
- Flavor Boosts: Add a dash of vanilla extract or a pinch of sea salt to enhance the overall flavor.
- Chocolate Choices: Use dark chocolate for an even richer taste or swap out for white chocolate if you prefer.
- Different Nut Butters: Try almond butter or cashew butter for a different taste experience; they all pair beautifully with chocolate.
