Let’s Make It Together
Making this Fudgy 1-Minute Brownie Mug Cake is not just easy; it’s a delightful little kitchen adventure. Here’s how to do it step-by-step:
Start by melting the butter in your favorite mug in the microwave for about 20 seconds, or until fully melted.
Add in the semi-sweet chocolate chips and stir until completely melted, microwaving for an additional few seconds if needed to get that glossy, dreamy chocolate mixture.
Now, it’s time to add in the egg yolk, brown sugar, and vanilla extract if you’re using it. Stir until everything is beautifully incorporated and smooth.
Sprinkle in the flour and give it a gentle stir, just until the flour disappears—don’t overmix!
If you love extra chocolate (who doesn’t?), fold in those optional chocolate chips into the batter before moving to the next step.
Cook your brownie mug cake on high in the microwave for 45 seconds. Every microwave is different, so keep an eye on it! If it needs a little extra time, give it another 15 seconds.
