What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 2 tablespoons butter softened
- 3 tablespoons all-purpose flour
- 2 tablespoons brown sugar packed
- 2 tablespoons white chocolate chips
- 1 tablespoon chopped macadamia nuts
- 1 large egg yolk
Step by step instructions
Step 1: Cream Butter and Sugar
In a large microwave-safe mug, combine softened butter and brown sugar. Stir vigorously with a fork for about 30 seconds until the mixture is creamy pale and well combined.
Step 2: Add Egg and Flour
Add the egg yolk and mix until incorporated. Add the flour and stir until a thick cookie dough forms, scraping the sides of the mug to incorporate all the flour.
Step 3: Fold in Mix-ins
Fold in the white chocolate chips and chopped macadamia nuts, reserving a few to press on top for a bakery-style appearance.
Step 4: Microwave and Rest
Microwave on 50 percent power for 60 to 80 seconds until the edges are set but the center still looks slightly underdone. Rest for 2 minutes as it will continue cooking from residual heat to a perfect gooey center.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- macadamia nuts → cashews or pecans for a similar buttery crunch
- white chocolate chips → butterscotch chips or regular semi-sweet chocolate chips
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Microwaving on full power which cooks the edges too fast and leaves the center rubbery
- Not resting the cookie after cooking and missing the crucial residual cooking time that creates the gooey center
