FAQs

Can I make this vegan?

Yes! Use oil instead of butter and plant-based milk. Make sure any add-ins (like chocolate chips) are vegan too.

Can I double the recipe?

It’s best to make one serving per mug. Doubling may cause overflow or uneven cooking.

What if I don’t have cocoa powder?

Cocoa powder is essential for the rich chocolate flavor. There’s no direct substitute in this case.

Why is my brownie rubbery?

Overmixing or overcooking can lead to a rubbery texture. Mix just until combined and watch your microwave time carefully.

Can I make this in a bowl?

Yes, just be sure it’s microwave-safe and similar in volume to a mug.

Can I add baking powder?

It’s not necessary. This brownie is meant to be dense and fudgy, not cakey.

How do I make it extra gooey?

Under-microwave by a few seconds and stir in extra chocolate chips.

Can I add eggs?

No eggs are needed in this single-serve recipe and may result in a rubbery texture if added.

How can I make it gluten-free?

Use a gluten-free 1:1 flour blend. Texture may vary slightly.

Can I bake it in the oven?

This recipe is designed for the microwave, but you could try baking at 350°F for 10–12 minutes in a ramekin.

Conclusion

The One-Minute Microwave Brownie is a quick and satisfying dessert fix that’s rich, chocolatey, and ready in a flash. It’s perfect when you want something sweet, fast, and just for you—with minimal mess and maximum flavor. Keep this recipe handy—you’ll come back to it again and again.

Description

This One-Minute Microwave Brownie is the ultimate single-serve dessert when you’re craving something sweet and chocolatey, but don’t want to wait. It’s gooey, fudgy, and comes together in one mug with just a few pantry staples—no oven required!


Ingredients

  • 1/4 cup all-purpose flour

  • 1/4 cup granulated sugar

  • 2 tbsp unsweetened cocoa powder

  • Pinch of salt

  • 2 tbsp vegetable oil (or melted butter)

  • 2 tbsp water (or milk, for a richer taste)

  • 1/4 tsp vanilla extract (optional)

  • 1 tbsp chocolate chips (optional, for extra gooeyness)


Instructions

  1. In a microwave-safe mug (10–12 oz size), whisk together flour, sugar, cocoa powder, and salt.

  2. Stir in oil, water (or milk), and vanilla extract until smooth and combined.

  3. Fold in chocolate chips if using.

  4. Microwave on high for 50–60 seconds. Don’t overcook—edges should look set, but the center can be a little soft.

Notes

  • Mug size matters—use a larger mug to prevent overflow.
