Copycat Keto Reese’s Peanut Butter Eggs are easy to make and fun to eat. You can make 18 small peanut butter cups.  These truly do remind me of Reese’s peanut butter cups.

I  originally made these back in the Spring for Easter, but now Halloween is right around the corner and they will be perfect for any sugar free diet.

My friends and family loved the texture of the peanut butter cream.  I think the peanut butter to butter ratio at 4 to 1 is perfect. That means one cup of peanut butter to 1/4 cup butter (or half stick). To this, we add in Swerve confectioner’s sweetener, and just a little bit of black strap molasses. You do need to make sure your peanut butter is very smooth. If you use a natural peanut butter that has oil on top, stir it extremely well.

Measure Peanut Butter with Food Scale

The only tricky part is measuring peanut butter. You can use a measuring cup which gets sticky, but in this post here, I  talked about weighing peanut butter and keeping the mess factor down. Read the back of your peanut butter and figure out how many grams you will need. The Kirkland peanut butter is 32 grams per 2 tablespoons or 16 per tablespoon. You need 8 tablespoons which is 128 grams. You will love the ease of weighing peanut butter.

    Over the years, I’ve attempted these things several times (White “holiday” Reece’s cups are one of my major weaknesses) but I always end up pissed off lol.
    Gave this a try because it seemed like an easy recipe and relatively, much less work.
    I could kiss you! These are thr best! The easiest. I’m about to make them again.
    I have one question and one silly “tip”
    My question is, did I miss instructions for adding the molasses? I’m a big fan of a small amount in keto recipes. It makes all the difference sometimes.
    Also, if you’re making “eggs” I found that rolling them into a ball and then using your thumb and index finger as a shaper worked wonderfully well and kept them uniform. No mold needed. (Like the universal “ok” sign but slide both fingers out a smidge. You can then pat the pattie smooth and add or take away to get equal thickness.
    Thanks so much!
