Ingredients
Method
- In a small microwave-safe bowl, combine softened butter, brown sugar, and granulated sugar. Mix with a fork until creamy and well combined. The mixture should look smooth with no lumps of butter visible.
- Stir in the egg yolk and vanilla extract until completely incorporated.
- Add flour and salt to the mixture, stirring just until combined. Don't overmix – you want the flour to disappear into the dough without developing too much gluten.
- Gently fold in chocolate chips, distributing them evenly throughout the dough. Press the dough into a round cookie shape, about 3 inches wide, directly in your microwave-safe bowl.
- Microwave for 60-90 seconds, depending on your microwave's power. The cookie is ready when the edges look set but the center still appears slightly underdone. It will continue cooking from residual heat.
Notes
Best enjoyed immediately while warm. Don't use cold butter - it won't cream properly. Avoid overcooking as the cookie continues cooking after removal. Never skip the salt as it enhances chocolate flavor. The dough should be slightly sticky for perfect texture. Can substitute coconut oil for dairy-free option or swap half flour with oat flour for extra fiber. Keep pre-measured dry ingredients in containers for faster assembly.
