Ingredients for Chocolate Chip Mug Cake
Here is everything you need for this easy chocolate chip mug cake:
- 1 tablespoon salted butter, melted
- 1 tablespoon granulated sugar

- 1/4 teaspoon vanilla extract
- 1 egg yolk
- 1 tablespoon milk
- 1/4 cup all-purpose flour, measured correctly

Ingredient Notes
Why brown sugar matters
Brown sugar adds moisture and gives the mug cake a richer, cookie-like flavor.
Why mini chocolate chips work best
Mini chips spread more evenly through the batter, so every bite gets a little chocolate.
How to measure flour correctly
Spoon the flour into the measuring cup, then level it off. Do not pack it down. Too much flour can make the mug cake stiff and dry. For extra baking accuracy, this guide on measuring flour correctly is very helpful.

Tips for the Best Chocolate Chip Mug Cake
Do not overmix
Stir only until the flour disappears. Overmixing can make the cake dense.
Do not overcook
Microwaves vary, so start with 60 seconds and check the texture. The cake should look set on top but still soft inside.
Use the right mug size
Choose a medium or large mug so the batter has space to rise.
Let it rest briefly
A short rest of 1 minute helps the texture settle and makes the cake even better.

Refined Sugar-Free Option
Swap the sugars for coconut sugar.
