Most recipe testers preferred a plain protein powder in this recipe, but vanilla also works.

We like maple syrup labeled “Grade A: Dark Color and Robust Taste” — we find it has the best flavor.

The recipe as written uses a thin layer of chocolate for a healthy snack. For a chocolate PB dessert variation, use 2/3 cup dark chocolate chips. When you use more chocolate, you can also make it in an 8 x 8 pan for a more even chocolate to peanut butter ratio.

We have not tested this recipe with other nut butters, but it should work with almond butter, cashew butter, or sunflower butter.
