Mug Cake Recipe
Craving a warm, single-serving dessert that’s quick, easy, and microwavable? This Mug Cake Recipe delivers a fluffy, chocolatey treat (or vanilla twist) in under two minutes—no baking fuss, no oven heat.
From the moment I first tried this microwave mug cake, I was hooked. It’s that perfect blend of comfort and convenience, ideal for rainy afternoons curled up with a good book—or those late-night sweet tooth emergencies. What makes this dessert special is its simplicity: pantry staples, minimal cleanup, and total customization. I often serve it during impromptu coffee chats with friends or as a little “you deserve this” moment after a long workday. Plus, it feels surprisingly healthier than lugging out a whole tray of brownies—just one portion, perfectly portioned, with options for gluten-free or dairy-free swaps.

Ingredients
• 4 tablespoons (¼ cup) all-purpose flour
(Substitute cup-for-cup gluten-free flour blend, such as Bob’s Red Mill.)
• 2 tablespoons granulated sugar
(Try coconut sugar for a subtle caramel note.)
• 1 tablespoon unsweetened cocoa powder for chocolate version
(I swear by Hershey’s Special Dark for extra richness.)
• ¼ teaspoon baking powder
(Look for aluminum-free brands to avoid any bitter aftertaste.)
• Pinch of salt
• 3 tablespoons milk (dairy or any non-dairy milk)
(Whole milk gives a richer crumb; oat milk lends creaminess.)
• 1 tablespoon melted butter or vegetable oil
(Butter adds flavor; coconut oil makes it fudgier.)
• ½ teaspoon pure vanilla extract for a vanilla mug cake or to enhance chocolate
• Optional add-ins: chocolate chips, chopped nuts, fresh berries
Directions
- Prep your mug: Lightly grease an 8-ounce microwave-safe mug with cooking spray or a dab of butter. This helps the cake release cleanly.
- Combine dry ingredients: In the mug, whisk together flour, sugar, cocoa powder (if making chocolate), baking powder, and salt until no lumps remain. A tight whisk or fork works wonders here.
- Stir in wet ingredients: Pour in milk, melted butter (or oil), and vanilla extract. Use a spoon to stir just until the batter is smooth—don’t overmix or the cake may turn dense.
- Customize: Gently fold in a tablespoon of chocolate chips or swirl in a teaspoon of fruit jam if you’re craving a twist.
- Microwave on high: Cook for 70–90 seconds at full power (1000W microwave). Start checking at 70 seconds—when the top springs back and a toothpick comes out with a few moist crumbs, it’s done.
- Let it rest: Allow the mug cake to sit for 1–2 minutes. It will continue to cook and firm up as it cools slightly.
- Enjoy straight from the mug: Top with a scoop of ice cream, a dusting of powdered sugar, or a drizzle of caramel sauce—whatever speaks to your sweet tooth.
Servings & Timing
Makes: 1 single-serving mug cake
Prep Time: 2 minutes
Cook Time: 1–2 minutes (depending on your microwave’s wattage)
Total Time: Approximately 5 minutes, including resting
Variations
• Peanut Butter Swirl: Drop a teaspoon of creamy peanut butter into the center before microwaving for a gooey surprise.
• Vanilla Dream: Skip the cocoa and add an extra ½ teaspoon of vanilla extract plus a pinch of cinnamon.
• Berry Bliss: Fold in a tablespoon of fresh or frozen blueberries to the batter for a fruity burst.
• Mocha Magic: Stir in ¼ teaspoon instant espresso powder to your chocolate mug cake for coffee-infused depth.
• Cake Mix Shortcut: Use two tablespoons of boxed chocolate cake mix, reduce flour by two tablespoons, and proceed as directed.
• Keto-Friendly: Swap sugar for 1½ tablespoons erythritol and use almond flour (2½ tablespoons) for a low-carb twist.
Storage & Reheating
Because this mug cake is best fresh, leftovers aren’t typical—but if you do have any:
• Refrigerate in an airtight container for up to 24 hours.
• Reheat in 10-second bursts in the microwave until warm, being careful not to dry it out.
• To freeze: Pop the cooled cake (crumbs and all) into a freezer-safe bag for up to 1 month; thaw in the fridge overnight, then microwave briefly.
• Make-ahead hack: Mix dry ingredients in a labeled jar; stash in the pantry. When the craving hits, just add wet ingredients in your mug.
Notes
I’ve tested this recipe on both my old 800W microwave and a shiny new 1000W model—timing can vary by up to 20 seconds, so start checking early. Also, ceramic mugs tend to cook more evenly than metal-rimmed or glass cups. If your cake sinks in the middle, it’s usually from under-cooking—just zap for an extra 10 seconds and let it rest. For the fluffiest crumb, don’t skip the rest period; I know it’s tempting to dive right in!
FAQs
• Can I make this dairy-free?
Absolutely—swap the milk for almond, soy or oat, and use coconut oil in place of butter.
• What if I don’t have cocoa powder?
Use a boxed chocolate cake mix (about 2 tablespoons) and reduce flour to 2 tablespoons—sweet and simple.
• How do I know when it’s done?
The top should spring back when gently pressed, and a toothpick should come out with just a few moist crumbs.
• Why did my mug cake turn rubbery?
Over-microwaving is usually the culprit. Next time, cut back the time by 10–15 seconds and let it stand.
• Can I add an egg for extra richness?
Yes—crack in one small egg, whisk well, and cook for an additional 10–15 seconds. Texture will be more custardy.
• Is it okay to double the recipe?
You can double ingredients in a larger mug, but cooking time will increase—start with 2 minutes and adjust in 15-second intervals.
• Can I bake this in the oven?
Sure—pour batter into a greased ramekin and bake at 350°F for 12–15 minutes, or until a toothpick comes out clean.
• Is this recipe healthy?
Compared to a full pan of cake, yes—portion control helps, plus you can lighten it further with natural sweeteners or whole-grain flour.
Conclusion
This Mug Cake Recipe proves that decadent desserts don’t have to be complicated. With just a handful of ingredients, you’ll enjoy a single-serving chocolate or vanilla treat in minutes—perfect for busy days, unexpected guests, or whenever you need a cozy pick-me-up.
