Ingredients & Step-by-Step Guide
The 5 Essential Ingredients You Need
The best part about making these 5-Ingredient Keto Peanut Butter Cups (Sugar Free) is that you don’t need a long grocery list. Each ingredient plays a role in flavor, texture, and keeping the recipe keto-friendly. Here’s what you’ll need:
- Sugar-free chocolate chips – These form the shell and give that rich chocolate bite without carbs. Look for brands sweetened with stevia or monk fruit.
- Natural peanut butter – Unsweetened, creamy peanut butter works best. It should have just peanuts (and maybe a little salt) in the ingredient list.
- Coconut oil – This helps the chocolate melt smoothly and set with a glossy finish.
- Low-carb sweetener – A powdered sweetener like erythritol, allulose, or monk fruit makes the filling perfectly sweet.
- Vanilla extract or sea salt – These little extras bring balance and depth to the flavor.
If you don’t have peanut butter, you can easily swap in almond butter, sunflower seed butter, or even hazelnut butter. The recipe is forgiving, so you can adjust based on what you already have in your pantry.

Step-by-Step Instructions Made Simple
Making keto peanut butter cups is surprisingly easy, even if you’ve never made candy before. Here’s the simple process:
- Melt the chocolate – Combine sugar-free chocolate chips with coconut oil in a microwave-safe bowl or double boiler. Heat until smooth and glossy.
- Layer the base – Spoon a small amount of melted chocolate into silicone cupcake molds or paper liners. Tilt the mold slightly to coat the bottom evenly. Chill until firm.
- Mix the filling – Stir together peanut butter, powdered sweetener, and a splash of vanilla until creamy.
- Add the peanut butter layer – Drop a spoonful of filling onto each chilled chocolate base. Spread gently without reaching the edges.
- Top with more chocolate – Cover the peanut butter layer with remaining melted chocolate, making sure it seals around the edges. Chill again until fully set.
Once firm, pop them out of the molds and enjoy! These store wonderfully in the fridge for up to a week or in the freezer for months. In fact, I often make a double batch so I always have a quick keto dessert on hand.
Variations & Creative Twists
Fun Flavor Additions
Once you’ve mastered the classic version of 5-Ingredient Keto Peanut Butter Cups (Sugar Free), it’s fun to get creative. A sprinkle of flaky sea salt on top not only adds crunch but also enhances the chocolate’s richness. For extra texture, try stirring chopped nuts, shredded coconut, or even a dusting of unsweetened cocoa powder into the peanut butter filling. If you’re a fan of spice, a pinch of cinnamon or cayenne can give each bite a warm, surprising kick.
Nut butter swaps are also an easy way to refresh the recipe. Almond butter offers a slightly sweeter taste, while sunflower seed butter keeps it nut-free and allergy-friendly. If you’re feeling indulgent, blend a bit of keto-friendly protein powder into the filling for an energy-boosting snack. Each variation adds its own twist while staying true to the keto lifestyle.
Keto-Friendly Pairings
Keto peanut butter cups are delicious on their own, but they can also be part of a bigger moment. Pair one with your afternoon coffee for a café-style treat at home. They’re also perfect alongside a chilled glass of almond milk or coconut milk for a light dessert after dinner.
If you love hosting, try adding them to a keto-friendly dessert board with fat bombs, chocolate-dipped strawberries, and low-carb cookies. Not only do they add variety, but they also look beautiful when served with different toppings and flavors. Portion control is key on keto, but with these homemade cups, you can indulge without the guilt. Whether you enjoy them solo or share with friends, they’ll quickly become the highlight of any sweet spread.
