Brownie Mix in a Mug: Mug Cake Ingredients
- 4 Tbsp. vegetable oil
- 3 Tbsp. cocoa powder
- 1/4 tsp. salt
- 6 Tbsp. sugar
- 1 large egg
- 4 Tbsp. flour
- 1/4 tsp. baking powder
- 2 Tbsp. white chocolate chips
- 2 Tbsp. milk or semi-sweet chocolate chips
- Optional: Vanilla ice cream and/or whipped cream to serve
- Optional: Powdered sugar to serve
For this mug brownie recipe, you can use either unsweetened cocoa powder or Hershey’s special dark cocoa powder. I have tried both, and both work deliciously!
I use a mix of white chocolate chips and semi-sweet chocolate chips for my mug cake mix. You can use dark chocolate chips in place of semi-sweet if you prefer, for a little more richness.
This double chocolate mug cake is the perfect size for sharing. It’s a great choice for Valentine’s Day! If you want to make a smaller portion, cut all of the ingredients in half (except for the egg) for an individual size chocolate chip mug cake.
How to Make a Brownie in a Mug
- In a coffee mug or other large mug, mix 4 Tbsp. vegetable oil and 3 Tbsp. cocoa powder until you have a thick, chocolatey liquid.
- Add in 1/4 tsp. salt and 6 Tbsp. sugar and thoroughly mix through until smooth.
- Using a fork, thoroughly mix in 1 egg.
- Carefully stir in 4 Tbsp. flour and 1/4 tsp. baking powder. Thoroughly mix together.
- Fold in 2 Tbsp. white chocolate chips and 2 Tbsp. milk or semi-sweet chocolate chips until evenly distributed.
- Microwave for 1 minute. The brownie in a mug will rise, then sink a little bit, and should still be wet to the touch.
Let your mug chocolate brownie cool for at least a couple of minutes – it will be very hot coming out of the microwave! I recommend using a large, sturdy mug to make your coffee mug cake.
For an even fudgier brownie cake in a mug, let it cool for about 10 minutes before eating. The melted chocolate chips make this a bit like a chocolate lava mug cake – ooey, gooey, delicious!
Serving Suggestions for Chocolate Brownie in a Mug
Serve your brownie mug with a scoop of vanilla ice cream and/or whipped cream. I love to top my mug brownie cake with a bit of powdered sugar, too. It adds a nice touch!
Another option is to top your brownie in a mug with sliced fresh strawberries. The little bit of tart from the strawberries adds a nice touch to a sweet chocolate mug cake!
Microwave brownies and mug cake recipes just don’t get any better than this gooey chocolate mug cake. I promise you, it’s the best chocolate mug cake recipe you’ll ever try!
Tips for How to Make Brownie in a Mug
- Combine with a fork: Use a fork to combine all your mug cake ingredients. It will mix better this way.
- Add a little flour to the chocolate chips: Mix the chocolate chips together, then sprinkle in a small amount of flour and toss together before adding to the mug. This keeps the chips from sinking to the bottom.
- Cook time based on microwave: Cook time for your microwave brownie recipe depends on the power of your microwave. The cook time here is for an 800W microwave. If you have a 700W microwave, for example, add an extra 40 seconds of cook time.
- Use a big mug: Use a big enough mug for your brownie in a cup! If you use too small of a mug, there’s a chance of the brownie mug mix overflowing. Don’t use a small mug.
