Ingredients for Your Cookie in a Cup

You probably have everything you need in your pantry right now:
Essential Ingredients:
- 1 tablespoon unsalted butter
- 1 tablespoon brown sugar (packed)
- 1 teaspoon white sugar
- 1/4 teaspoon vanilla extract
- Pinch of salt
- 1 egg yolk (save the white for another recipe)
- 3 tablespoons all-purpose flour
- 2 tablespoons chocolate chips
Why These Ingredients Matter:
- Butter: Creates that rich, cookie flavor and tender texture
- Brown sugar: Adds moisture and that classic cookie chewiness
- White sugar: Provides structure and helps with browning
- Egg yolk: Binds everything together without making it too dense
- Flour: Just enough to hold the cookie together
- Chocolate chips: The star of the show!
Step-by-Step Instructions: Perfect Cookie in a Cup Every Time

Step 1: Prepare Your Mug
Choose a microwave-safe ceramic mug that’s at least 8 ounces. Wider mugs work better than tall, narrow ones for even cooking.
Step 2: Melt the Butter
Place butter in your mug and microwave for 30 seconds until mostly melted. If needed, microwave in 10-second intervals.
Step 3: Mix the Base
Stir in brown sugar, white sugar, vanilla, and salt until well combined. The mixture should look smooth and caramel-colored.
Step 4: Add the Egg Yolk
Stir in the egg yolk until the mixture is completely smooth with no streaks.
Step 5: Incorporate Dry Ingredients
Add flour and mix until just combined. Don’t overmix! Fold in most of the chocolate chips, saving a few for the top.
Step 6: Microwave Your Cookie in a Cup
Sprinkle remaining chocolate chips on top. Microwave on high for 45-60 seconds. The cookie should puff up and look set on top.
Step 7: Cool and Enjoy
Let cool for 2-3 minutes before digging in. The cookie will be very hot!
