Directions
0.
Mix flour, peanut butter, egg, and water together into a firm dough.
1.
Roll into small flat rounds about 1/4-inch thick.
2.
Place on a microwave-safe plate lined with parchment, a few at a time.
3.
Microwave on high in 1-minute bursts, checking often, until firm and dry — about 4–5 minutes total.
4.
Cool completely before serving, as biscuits firm up further while cooling.
