Mug Cake Basics
- This easy microwave chocolate mug cake recipe is perfect for busy days when you need a homemade dessert fast.
- A mug cake is a single-serving cake made right in a mug and cooked in the microwave.
- These single-serve cakes are popular because they’re fast, require minimal ingredients, and satisfy dessert cravings in minutes.
- Personally, I love how it saves me from having to pull out all my baking tools for just one slice of chocolate heaven! Perfect for a cake lover like me.
Ingredients You’ll Need

- Butter: Adds rich flavor and keeps the cake moist. Melt it first for easy mixing.
- All-purpose flour: Gives the cake its soft, sturdy texture.
- Granulated sugar: Sweetens the cake without overpowering the chocolate.
- Cocoa powder: Use unsweetened cocoa powder for the best deep chocolate flavor.
- Dark chocolate chips: Melt into gooey pockets of extra chocolate. (I always use the good stuff like Guittard or Ghirardelli!)
- Baking powder: Helps the cake rise and stay light.
- Large Egg: Binds everything together and keeps the cake tender.
- Water: Adds moisture. You can swap in milk for an even creamier texture.
- Vanilla extract: Adds a hint of warm flavor that makes the chocolate shine. Make homemade vanilla or buy good-quality vanilla.
How To Make A Chocolate Mug Cake
Get prepared, because this is going to be fast!
Step 1. Add the butter to the mug and microwave for 45 seconds to melt.
Tip – I usually melt the butter first while grabbing the other ingredients.


Step 2. Add the remaining ingredients to the mug and mix well with a fork.


Step 3. Place the mug back into the microwave and cook for 70-90 seconds. The cake should pull away from the sides of the mug and appear somewhat dry on top.

Step 4: Let the cake cool for about 5-10 minutes before eating.

And like magic, you will have an amazing chocolate dessert, just for you.
What To Pair This Mug Cake With
This cake is delicious enough on its own, but if you want to take it up a notch, consider these pairing options:
- Whipped cream: Light and fluffy for an extra indulgent touch.
- Vanilla ice cream: The cool, creamy texture balances the warm cake.
- Fresh berries: Add a tart contrast to the rich chocolate flavor.

Tips for Baking Success
- Use the Right Mug: Ensure your mug is microwave-safe and large enough to prevent overflow. An 8 to 12-ounce mug works well, or use a ramakin.
- Mix Thoroughly: Ensure your ingredients are well combined, especially the egg, to avoid clumps in your cake.
- Don’t Overcook: Start with 60 seconds and add time in 10-second increments if needed. Overcooking can result in a dry texture.
- Customize It: This is the perfect recipe to experiment with — I change it up depending on what I have in the pantry! Add a pinch of cinnamon, drizzle with caramel, or add some nuts, I like pecans.

Yes, you can use brown sugar or coconut sugar as a substitute for granulated sugar, although it may slightly alter the flavor.
