SERVINGS: 1 mug

Ingredients

  • 1 tbsp butter
  • 2 tsp coconut sugar
  • 2 tsp granulated monkfruit sweetener
  • 1/4 tsp vanilla extract
  • Pinch of salt
  • 1 egg yolk
  • 1 tbsp all-purpose flour + 2 tsp
  • 1 tbsp vanilla protein powder
  • 2 tbsp refined sugar free chocolate chips divided

Instructions

Enable step-by-step mode
  • Melt the butter in a microwave-safe mug (at least 10 oz) for 20 to 30 seconds.
  • Add coconut sugar and monkfruit sweetener. Stir until the mixture looks glossy and slightly thick.
  • Add vanilla extract, salt, and egg yolk. Stir until fully combined and smooth.
  • Add flour and protein powder. Stir until just combined. Stop the moment no dry streaks remain. Do not overmix.
  • Fold in most of the chocolate chips. Press the remaining chips on top of the batter surface without stirring them in.
  • Microwave on high for 35 to 45 seconds only. The center should look soft and slightly underdone when you stop.
  • Let rest for 2 full minutes before eating. The texture settles and the chocolate chips finish melting during this time.

Notes

Best eaten immediately while warm. If storing, cover and keep at room temperature for up to 24 hours. Microwave 10 to 15 seconds to rewarm.
Stop at 45 seconds maximum. The cookie looks underdone when you pull it and that is correct. It finishes in the residual heat during the rest.
Let it rest the full 2 minutes. The texture changes significantly and is much better for it.
Measure flour without packing. Spoon into the measuring spoon and level off. Too much flour makes it dry.
Use a protein powder you enjoy eating plain. The flavor stays present in a no-bake microwave recipe in a way it doesn't in oven-baked goods.
No monkfruit? Use all coconut sugar or brown sugar as a direct swap. No protein powder? Leave it out and add 1 extra teaspoon flour instead. Dairy-free? Use coconut oil instead of butter and dairy-free chocolate chips.
