I love white chocolate, especially with peanut butter. This combination reminds me of the peanut butter marshmallow sandwiches we ate as children when on vacation. The good news is keto white chocolate peanut butter cups is a much better choice when counting carbs.

Keto White Chocolate Peanut Butter Cups

The recipe is very similar to these keto dark chocolate peanut butter cups, made with Choc Zero chips. I wasn’t sure how the white chocolate chips would work, but once tempered, they work perfectly and give you the snap and taste of regular white chocolate.

Why Do We Temper Chocolate?

Tempering means melting chocolate that will come back together in texture and snap. When chocolate is not tempered, it will have to be refrigerated and will melt in your hand.

How to Temper White Chocolate

Tempering the sugar free white chocolate is no different than tempering regular white chocolate.

Use double boiler method: I prefer this over microwaving chocolate, especially white chocolate which can overheat easily. Simply put about an inch of water in saucepan and place a heat proof (stainless) bowl over the simmering water, but without the bowl touching. This is very important in order to keep a steady low temperature.

Typically, all you need to do is place 3/4 of the chocolate you need in the bowl and melt, stirring continuously and then taking chocolate off heat and adding in the rest of the chocolate. If you keep the heat low, and stir continuously, you can even add more chocolate in. You must make sure that not one drop of water gets in the bowl as the chocolate will seize up and not be usable.

I tempered the choc zero white chocolate chips three times to make sure this works, if directions are followed.

Measure Peanut Butter for Keto White Chocolate Peanut Butter Cups

The EASIEST way to measure peanut butter is to weigh it. The Kirkland peanut butter is 32 grams per 2 tablespoons or 16 per tablespoon. You need 8 tablespoons which is 128 grams. Once you have the peanut butter in the bowl and weighed, add remaining ingredients.

Invest in a food scale like the one I have and use every day.

Use small all silicone cups, which will remove your peanut butter cups easily and aren’t too big.

Ingredients for Peanut Butter Filling
