This decadent 3-minute chocolate mug cake combines the richness of cocoa with the tangy goodness of Greek yogurt for a guilt-free treat that satisfies those intense chocolate cravings without the fuss of a full-sized cake.
I created this recipe during a late-night chocolate emergency when my sweet tooth was demanding satisfaction but I didn't want to bake an entire cake. The first bite of that warm, molten chocolate center convinced me this would become my go-to dessert hack.
Ingredients
- Whole wheat flour: Provides a nutty flavor and extra fiber compared to all-purpose flour
- Unsweetened cocoa powder: Delivers intense chocolate flavor without added sugar; look for Dutch-processed for smoother taste
- Baking powder: Ensures your cake rises properly in the microwave
- Kosher salt: Enhances all the flavors, particularly the chocolate notes
- Milk: Creates the perfect batter consistency; any variety works depending on dietary preferences
- Nonfat plain Greek yogurt: Adds protein and creates a moist, tender crumb
- Pure maple syrup: Provides natural sweetness with subtle complexity
- Peanut butter: Contributes richness and a complementary flavor to chocolate
- Dark chocolate chips: Melt into pockets of gooey goodness throughout the cake
Step-by-Step Instructions
- Mix Dry Ingredients:
- Measure whole wheat flour, cocoa powder, baking powder, and salt directly into your microwave-safe mug. Thorough mixing at this stage prevents any bitter pockets of baking powder or cocoa. Use a fork to break up any clumps in the cocoa powder for the smoothest texture.
- Add Wet Ingredients and Combine:
- Pour in milk, dollop the Greek yogurt, drizzle maple syrup, and add the peanut butter. The order matters little, but mixing thoroughly does. Use your fork to incorporate everything, paying special attention to the bottom edges of the mug where dry ingredients like to hide. Fold in chocolate chips last, distributing them evenly throughout the batter.
- Microwave the Mug Cake:
- Place your mug on a paper towel in case of overflow. Microwave on high for approximately 90 seconds, watching carefully. The cake will rise dramatically but should not spill over in a properly sized mug. The perfect cake has a set exterior with a slightly gooey center. Every microwave varies in power, so your first attempt may require slight timing adjustments.
- Cool and Serve:
- Exercise patience for those crucial three minutes of cooling. The cake continues cooking from residual heat and will set to the perfect consistency. This also prevents burning your mouth on molten chocolate chips. The final texture should be springy around the edges with a soft, brownie-like center.

The Greek yogurt is truly the secret weapon in this recipe. I discovered its power when I accidentally used it instead of sour cream in another recipe, and was amazed at how it created such a tender crumb while adding protein. My husband now requests this as his birthday dessert instead of traditional cake.
Perfect Mug Selection
The ideal mug for this recipe holds at least 12 ounces with straight rather than sloped sides. This provides enough headroom for the cake to rise without overflowing. Ceramic mugs conduct heat more evenly than glass, resulting in more consistent cooking. Avoid using mugs with metallic trim or decorations as these can cause sparking in the microwave.
Easy Variations
Transform this basic recipe by switching up your add-ins. Try white chocolate chips with a swirl of raspberry jam for a fruity twist. Replace peanut butter with Nutella for an extra chocolatey experience. Add a teaspoon of instant espresso powder to the dry ingredients for a mocha flavor profile. For a holiday version, incorporate a drop of peppermint extract and top with crushed candy canes.
Make It Ahead
Though best enjoyed fresh from the microwave, you can prepare the dry ingredients mixture in advance. Combine all dry ingredients in small containers or zip-top bags for grab-and-go mug cake kits. When ready to enjoy, simply empty the premixed dry ingredients into your mug, add the wet ingredients, and microwave. This preparation saves precious minutes when dessert cravings strike.

Frequently Asked Questions
- → Can I use regular yogurt instead of Greek yogurt?
Yes, you can substitute regular yogurt for Greek yogurt, but your mug cake may have a slightly different texture. Greek yogurt provides more protein and a denser texture. If using regular yogurt, you might need to reduce the milk slightly as regular yogurt is thinner.
- → Is there a way to make this without a microwave?
Absolutely! You can bake this in a small oven-safe ramekin at 350°F (175°C) for about 15-18 minutes. The texture will be slightly different, but still delicious. Check for doneness with a toothpick inserted near the edge.
- → Can I make this dairy-free?
Yes, use plant-based milk (almond, oat, or soy), dairy-free yogurt alternatives, and dairy-free chocolate chips. The peanut butter and other ingredients are already dairy-free, making this easy to adapt.
- → What can I substitute for maple syrup?
Honey, agave nectar, or date syrup work well as 1:1 substitutes. For a sugar-free version, try a monk fruit sweetener or stevia (though you may need to adjust quantities as these are sweeter than maple syrup).
- → Why is my mug cake rubbery?
Rubbery texture usually comes from overcooking or overmixing. Try reducing your microwave time by 10-15 seconds, or mix the batter just until ingredients are combined. Also, allowing the cake to rest for 3 minutes after cooking helps improve texture.
- → Can I prepare this in advance?
You can mix the dry ingredients ahead of time and store them in the mug. When ready to eat, add the wet ingredients and microwave. For best results and texture, it's recommended to cook just before eating rather than microwaving in advance.
