Keto Peanut Butter Cup Recipe (No Sugar, Low Carb, and Tastes Better Than Reese’s!)

Halloween is just a few days away, and if you’re like me, this time of year is when candy bowls, office treats, and bright orange wreath wrappers seem to proliferate everywhere. It’s charming, nostalgic, and can trigger your old sweet tooth spiral faster than any other holiday.

But this is the truth. You don’t have to spend Halloween in a frenzy, and you don’t have to “miss out” on chocolate, peanut butter, and definitely your favorite combination.

These creamy, sugar-free, keto peanut butter cups taste just like Reese’s (honestly…even better), but won’t send your blood sugar on a roller coaster or cause regret, cravings, or a carb hangover.

Made with simple ingredients, no artificial flavors or sugar alcohols, and easy to assemble using silicone molds or muffin liners.

This is a low-carb sweet treat that will help you stay on track with your goals and enjoy something fun and delicious during candy season.

Before you want to go to the candy store on Halloween, we recommend making a big batch at home and chilling it for that moment. We’re sure you’ll love it!

Materials needed

How to make your own peanut butter cups (step by step)

Melt the chocolate and coconut oil in a microwave-safe or heatproof bowl. Add a thin layer to the tin or muffin liners to coat the sides. Freeze for 15 minutes. Melt the peanut butter and remaining coconut oil, then add the vanilla and sweetener. Spoon into hardened chocolate cups and refreeze. Cover with remaining chocolate and freeze until solid. Remove, enjoy, and store in the refrigerator or freezer.

Midlife Macro Method™ Make it Friendly (Red Day Option)

If you’re following my Midlife Macro Method™ and want a low-fat option on your red days, try the following swaps.

Reduce the coconut oil in the filling by half Use powdered peanut butter (PB2 style) as part of the filling to lower fat and calories Keep the serving size to 1 and pair with a high protein meal or snack

It tastes the same. Same satisfaction. Improved coordination during the fat loss phase.

Can I use unsweetened chocolate?

You can also use unsweetened chocolate, but it won’t be sweet at all and you’ll need to add more low-carb sweetener.

We do not recommend using unsweetened chocolate, as it does not contain as much milk fat, which provides milk chocolate’s famous taste. Using unsweetened chocolate may make it bitter.

Can I use dark chocolate?

You can also use dark chocolate in place of the sugar-free chocolate bars and chips used in this recipe. The more cocoa butter a chocolate bar contains, the lower the amount of sugar and carbohydrates. We recommend 85% dark chocolate.

Should I use silicone muffin cups?

There’s no need to use silicone muffin cups. Simply remove the peanut butter cup. If using metal muffin tins, use paper liners for easy removal.

Can I replace the sweetener?

Avoid using granular sweeteners in fillings. Use powdered allulose or monk fruit, or liquid stevia for a smoother texture.

Can I make this nut free?

If you’re not a peanut butter fan or have dietary restrictions, you can also make these with another nut butter of your choice, like almond, macadamias, or even cashews. You can also make it nut-free by using sunflower seed butter as a substitute.

Brenda’s top tips:

I purchased silicone molds to make traditional looking peanut butter wreath cups.

You can use any peanut butter you like, but I prefer this natural peanut butter because of the salt content. If you use unsalted peanut butter, we recommend adding sea salt. Otherwise, it won’t be like traditional peanut butter.

It may soften a bit if left on the counter at room temperature. It’s best to store it in the refrigerator until you want to enjoy it.
