The Method for Chocolate Chip Cookie in a Mug

Step 1: Melt the Butter
In a microwave-safe mug, melt the 2 tablespoons of unsalted butter. This should take about 20-30 seconds in the microwave.
Step 2: Mix in the Sugars
Add 2 tablespoons of sugar and 1 tablespoon of brown sugar to the melted butter. Stir well until combined.
Step 3: Add the Egg and Vanilla
Crack in one egg and add ½ teaspoon of vanilla extract. Mix until the egg is fully incorporated into the batter.
Step 4: Add Dry Ingredients
Sprinkle in ¼ teaspoon of salt, ¼ teaspoon of baking powder, 2 tablespoons of almond meal, and ¼ cup of oat flour. Stir until you have a thick batter.
Step 5: Fold in the Chocolate Chips
Finally, fold in ¼ cup of semisweet chocolate chips, ensuring they are evenly distributed throughout the batter.
Step 6: Microwave Your Cookie
Microwave the mug on high for about 40-60 seconds. Keep an eye on it, as microwave times may vary. You want the cookie to be set but still soft in the center.
Warm & Cool Weather Spins

- Warm Weather: Serve your cookie topped with a scoop of vanilla ice cream for an irresistible treat.
- Cool Weather: Enjoy with a drizzle of warm chocolate sauce or a sprinkle of cinnamon for added warmth.
Problems & Prevention
- Cookie Overflows: Use a larger mug to prevent overflow during microwaving.
- Dry Cookie: Avoid overcooking; it’s better to undercook slightly since the cookie will continue to cook in the mug.
- Hard Texture: If you find your cookie too hard, try adding a splash more butter or a bit of milk to the batter.
