- 1/4 tsp vanilla extract
- 1 large egg yolk
- 1/4 cup all-purpose flour

📋Instructions
- 1
In a microwave-safe mug (about 12 oz capacity), melt the butter in the microwave: about 20-30 seconds.
- 2
Add the granulated sugar, brown sugar, and vanilla extract. Stir well with a small fork or spoon until combined.
- 3
Add the egg yolk and stir vigorously until the mixture is smooth and slightly thickened.
- 4
Add the flour and stir until just combined — no dry streaks. Fold in the chocolate chips.
- 5
Microwave on high for 45 seconds to 1 minute 15 seconds. The cookie should be puffed and set on top but still slightly gooey in the center. Start checking at 45 seconds to avoid overcooking.
- 6
Let it cool for 1 minute in the mug. Sprinkle with sea salt if desired. Enjoy warm!
💡 Pro Tips
- •Use a microwave-safe mug that holds at least 12 oz to prevent overflowing.
- •Egg yolk is key for richness and a chewy texture — don't skip or substitute with whole egg.
- •Microwave times vary by wattage — if yours is over 1000W, start checking at 40 seconds.

Pro Tip for Perfect Mug Cookies
Always use a large enough mug (at least 12 oz) to allow the cookie to rise without spilling over. Also, microwaves vary widely — start with the minimum time and check. The cookie will continue to cook slightly as it cools, so it's better to undercook than overcook.
Variations & Customizations
This recipe is super versatile. Swap the chocolate chips for white chocolate, butterscotch, or even chopped peanut butter cups. Add a tablespoon of chopped nuts for crunch. Feeling fancy? Top with a scoop of ice cream after microwaving for an extra decadent treat. You can also stir in a teaspoon of cocoa powder for a double chocolate version — just reduce the flour by 1 tablespoon.
Serving Suggestions
This mug cookie is wonderful on its own, but you can take it up a notch. Serve it with a cold glass of milk, a dollop of whipped cream, or a scoop of vanilla ice cream. It's also perfect for a cozy night in or as a quick dessert when guests are over and you want something warm and impressive without the fuss.
