Method
 

Preparation
  1. In a microwave-safe mug, melt the butter in the microwave for about 20-30 seconds until it’s fully melted.
  2. Add the granulated sugar and brown sugar to the melted butter, stirring well to combine until it’s smooth and creamy.
  3. Mix in the vanilla extract and a pinch of salt to enhance the flavor.
  4. Add the egg yolk to the mixture and stir until fully blended.
  5. Gradually mix in the flour and ground cinnamon until everything is incorporated. Make sure you don’t have any lumps!
  6. If you’d like a little added sweetness, sprinkle more sugar on top for that signature snickerdoodle crunch.
  7. Pop the mug into your microwave and cook for 40-60 seconds, depending on the strength of your microwave. It should look fluffy and cooked through but still soft in the center.
  8. Let it cool for a minute before diving into your delicious creation!

Notes

Store leftover cookie in an airtight container at room temperature for up to 1 day. To reheat, microwave for 10-15 seconds. For larger batches, freeze the cookie dough in portions and defrost in the fridge before cooking.
