keto peanut butter cups

Keto peanut butter cups will more than satisfy your chocolate and peanut butter cravings and you won’t feel guilty afterwards!

Reese’s peanut butter cups are highly processed, carb rich, nutrient poor and are designed to be addictive. These keto peanut butter cups use all natural ingredients without carbohydrates and sugar.

This means you can enjoy the creamy, gooey peanut butter covered by a sinful dark chocolate shell and not feel bad!

what chocolate do you use for keto peanut butter cups

The chocolate I use and LOVE is Lilys because it tastes amazing and there’s no sugar, only stevia. It’s the only chocolate I can keep around the house. I’m actually able to just have a portion, which is a foreign concept to me with other chocolates. I’m the person who buys horrible, non-chocolate candy at Halloween JUST so I don’t eat it all before kids knock on the door.

You don’t have to use Lily’s, any dark chocolate will work.

The coconut oil, which is added to the chocolate, creates a firm consistency once chilled and makes the chocolate easier to spread.

(Fun fact: if you use unrefined coconut oil it won’t taste/small like coconuts if you’re not a fan).

Melt the chocolate and coconut oil in a microwave bowl in 30 second stints, stirring after each time. Be careful not to over cook – shouldn’t take more than 1 minute total.

You can also use a double-boiler on the stove top to slow cook the chocolate.

I used home made peanut butter which is very easy to make. Simply add peanuts (any kind: roasted, raw, salted, unsalted) to a sturdy food process and press GO. Timing depends on your food processor. It typically takes mine five minutes before I achieve a smooth, butter consistency.

Store bought peanut butter works just as well, I would use a natural brand like Crazy Richards.

assembling the keto peanut butter cups

Add about a teaspoon of chocolate into each liner.

TIP: to get it to spread evenly across entire bottom of cup, bang the pan on the counter a couple of times. Once all cups are filled, stick the pan in the freezer for at least 10 minutes until they’re hard.
