Great recipe Megan! I love the texture of my protein isolate with nut butters.
For those of you wanting weight in grams, type in a search engine, the following (without the quotes):
“weight of xx cups of INGREDIENT”
and add “in grams” if you prefer grams to ounces.
Butter: 1/3 cup 76 g
Peanut Butter Smooth: 1/2 cup 125 grams
Sweetener and protein powder are much easier to measure in cups, but if you need them in weight measurements, now you know how.
Just made these with Almond Butter, they are amazing!!! Thanks so much for all your recipes, on the website and in your books, you’ve made Keto fun again!!!
So quick and easy to make and they fill that desire for a quick sweet treat! Yummo!I am glad you enjoyed the Helen. I just found a few jars of nut butters so I guess I will have to make some too!
