What Makes This Recipe So Good
- These low-carb peanut butter cups are every bit as good as traditional Reese’s Peanut Butter Cups, without all the carbs and added sugar!
- Some variations mix coconut oil into the chocolate, but the oil changes the flavor just enough that the cups don’t taste quite right. They’re good, sure, but if you’re going for an authentic Reese’s copycat, they’re a little off. This recipe, on the other hand, is just chocolate, peanut butter, and erythritol, so the flavors are perfect.
- “Can’t I just buy sugar-free Reese’s cups?” Well, you can, BUT! They contain maltitol – a sugar substitute that is really not great for you. Maltitol can cause a lot of stomach distress, like bloating and diarrhea. The glycemic index of maltitol is almost as high as regular sugar, so it’s actually not a keto-friendly sugar substitute, even though it’s technically low carb. The 40 Aprons recipe, though, is completely keto-friendly!
Keto Peanut Butter Cups Ingredients
Chocolate – Be sure to use sugar-free/low-carb chocolate chips, to keep the carb count as low as possible. I like to use Lily’s Milk Chocolate Chips for this recipe to make it as close to traditional Reese’s cups as I can get. A serving of Lily’s chips only has 1g of net carbs!
Peanut Butter – If you’ve ever checked the labels on peanut butters, you know the macros are all over the place and completely dependent on the brand. Look for peanut butters that have the fewest ingredients – try to find ones that only use peanuts and maybe salt if you can. Avoid “low” or “reduced fat” labels, as those usually have added sugar to make up for the lack of fat. Smucker’s Natural Creamy Peanut Butter is a great option, at only 4g net carbs per serving.
How to Make Keto Peanut Butter Cups
The full recipe & ingredients list are below, but here you’ll find a quick overview for making this recipe perfectly, along with useful tips and info!
Line a cupcake pan with cupcake liners, then fill each liner partway with a little melted chocolate. Layer the peanut butter/erythritol mixture on top of the chocolate, then pour a little more melted chocolate on top of the peanut butter.
Once they’re assembled, refrigerate the peanut butter cups for an hour, or until the chocolate is hardened.
Chef’s Tips
- Sifting the powdered erythritol is super important – don’t skip that step! If you don’t sift it, the erythritol will clump, and the consistency of your keto peanut butter cup filling will be all wrong.
- To reduce the chances of the peanut butter cups sticking to the cupcake liners, use parchment paper liners or silicone liners.
- For an extra punch, try sprinkling a little sea salt on top of your peanut butter cups before you put them in the refrigerator. Salt wakes up your taste buds and enhances the sweet flavors in these treats. Don’t go overboard, though – too much salt will dampen the sweetness.
- Keep the peanut butter cups refrigerated until you’re ready to eat them. They’ll soften if left at room temperature too long, and while they’ll still be delicious if they soften, they’ll be messy.
