Method
- 1.
Mix the wet ingredients — In a small microwave-safe mug or ramekin, stir together the peanut butter, brown sugar, white sugar, egg yolk and vanilla extract until smooth.
- 2.
Form the cookie dough — Add the flour, baking soda and salt, and mix well until a thick, uniform cookie dough forms.
- 3.
Fold in chocolate chips — Fold in the chocolate chips and press the dough down evenly into the base of the mug.
- 4.
Microwave until set — Microwave on medium power (about 50%) for 40 seconds, checking at 30 seconds, until the edges look set but the centre is still slightly soft.
- 5.
Cool briefly and enjoy — Let the cookie cool in the mug for 2-3 minutes, since it will keep firming up as it sits, then eat it warm straight from the mug with a spoon.
