Craving a warm, gooey chocolate chip cookie right now? This chocolate chip cookie mug cake is your instant dessert fix—no oven, no fuss, just sweet satisfaction in minutes! It’s my favorite way to treat myself when I want something homemade without the wait (or the dishes).

I’ve made this more times than I can count, sometimes as a late-night snack, other times as a midday pick-me-up. It’s perfect for those moments when you just need a cookie but don’t want to make a whole batch. Bonus: you only need a few pantry staples and one mug to make it happen.

Ingredients you’ll need

This cookie mug cake recipe comes together in just minutes with pantry staples you probably already have on hand. Here’s what you’ll need:

Bowls with chocolate chips, brown sugar, butter, flour and vanilla.
  • Unsalted butter: Adds richness and that classic cookie flavor. Melt it first for easy mixing.
  • Milk: Keeps the cake moist; any kind (dairy or non-dairy) will work just fine.
  • Brown sugar: Sweetens the cake and adds a soft, caramel-like depth.
  • Vanilla extract: Enhances the cookie flavor and adds warmth.
  • Salt: Just a pinch helps balance the sweetness and boosts flavor.
  • All-purpose flour: Creates the structure—start with less and add more if needed to avoid a dry texture.
  • Baking powder: Gives the mug cake a little lift and lightness.
  • Semi-sweet chocolate chips: These melt into gooey pockets of chocolatey goodness with every bite!

Author: Kim

Ingredients

  • 1 tablespoon unsalted butter
  • 2 tablespoons milk, dairy or nondairy works
  • 2 tablespoons brown sugar
  • 1/4 teaspoon vanilla extract
  • pinch of salt
  • 3-4 tablespoons all-purpose flour*

Instructions 

  • Add the butter to an 8-ounce microwave-safe mug and microwave for about 30 seconds, or until mostly melted.
  • Stir in the milk, brown sugar, vanilla and salt until combined.
  • Stir in the flour, baking powder and most of the chocolate chips until combined.
  • Sprinkle the top with the remaining chocolate chips. Microwave on high for 1 minute and 25 seconds.
  • Let cool for about 5 minutes before enjoying. I love this served with a scoop of vanilla ice cream!

Notes

*I usually use 4 tablespoons (or 1/4 cup) of all-purpose flour for this mug cake, but if you prefer a moister texture, try 3 tablespoons instead—it still works beautifully! Just note that with less flour, the cake will be a bit smaller.
**Please note that ALL microwaves are different therefore can yield different results and can overcook this mug cake if you aren’t careful. When trying this recipe for the first time, you might want to start with a 60-70 second cooking time at 100% power. When done the cake will puff up and appear dry.

Recipe tips

  • Use a microwave-safe mug: Make sure your mug is at least 8 ounces and microwave-safe to avoid overflow or cracking.
  • Don’t overmix: Stir just until the ingredients are combined. Overmixing can lead to a tough texture.
  • Adjust cook time if needed: Microwave strengths vary, so start with 1 minute and 25 seconds, and add a few more seconds if needed. The center should look just set.
  • Let it cool slightly: It will be hot right out of the microwave, and letting it sit for 5 minutes helps it firm up a little and improves the texture.
  • Customize your chips: Try dark chocolate, white chocolate, or even peanut butter chips for fun flavor twists!

Frequently asked questions

Can I make this mug recipe without a microwave?

I haven’t actually tried baking this mug cake, but it should work. Try baking it in an oven-safe ramekin at 350°F for about 10–12 minutes. Just keep an eye on it so it doesn’t over-bake.

Why is my mug cake rubbery or dry?

This usually happens if it’s overcooked. Microwave ovens vary, so start with a shorter cook time and add a few seconds if needed.

Can I use oil instead of butter?

Yes, you can swap melted coconut oil or vegetable oil for butter, but butter adds a richer flavor.

Can I make this ahead or store leftovers?

This cookie mug cake is best enjoyed fresh. Leftovers can turn dry and lose the soft, gooey texture.
