Are you craving something sweet but want to stay on track with your keto lifestyle? I’ve got the perfect solution for you. This keto mug cake is about to become your new favorite go-to dessert. It takes just minutes to make and satisfies that chocolate craving instantly.
I love making this single-serving chocolate mug cake when I need a quick treat. The best part is you probably have all the ingredients in your pantry right now. No fancy equipment needed, just a mug and a microwave. This recipe is so simple that even kids can make it with minimal supervision.
The texture of this keto mug cake is absolutely incredible. It comes out moist, fudgy, and perfectly chocolatey every single time. I’ve made this recipe dozens of times and it never disappoints. Whether you need a late-night snack or a quick dessert after dinner, this fits the bill.
One of my favorite things about mug cakes is how customizable they are. You can adjust the sweetness level to your preference easily. Add a dollop of whipped cream on top for extra indulgence. Some nights I even throw in a few extra chocolate chips because why not?
This low carb dessert contains only a fraction of the carbs in traditional cakes. You won’t believe it’s keto-friendly when you taste how rich it is. The almond flour gives it a wonderful texture without any graininess. I use erythritol as my sweetener because it doesn’t have that artificial aftertaste.
Making desserts on a ketogenic diet can feel challenging at first. I remember feeling frustrated trying to find recipes that actually tasted good. This keto mug cake changed everything for me. It proved that you don’t have to sacrifice flavor when eating low carb.
The combination of cocoa powder and chocolate chips creates incredible depth of flavor. I specifically use Lily’s chocolate chips because they’re sweetened with stevia. They melt beautifully and add pockets of gooey chocolate throughout the cake. Trust me, this simple ingredient makes a huge difference.
What I appreciate most is how forgiving this recipe is. Forgot to add the baking powder until the end? No problem, just stir it in. Your egg is a little small? The cake will still turn out great. This flexibility makes it perfect for beginners and experienced bakers alike.

Ingredients, Instructions & Pro Tips
Recipe Overview
Prep Time: 5 minutes | Cook Time: 2 minutes | Total Time: 7 minutes
Servings: 1 | Difficulty: Easy
Ingredients Table
| Ingredient | Quantity | Notes |
|---|---|---|
| Melted Butter | 1 tbsp | Unsalted or salted works fine |
| Egg | 1 large | Room temperature preferred |
| Almond Flour | 1/4 cup | Finely ground, blanched |
| Erythritol | 1 tbsp | Can substitute with monk fruit |
| Cocoa Powder | 1 tbsp | Unsweetened, Dutch-processed ideal |
| Baking Powder | 1/2 tsp | Ensures fluffy texture |
| Lily’s Chocolate Chips | 1 tbsp | Sugar-free, stevia-sweetened |
Instructions
Step 1: Prepare Your Mug Start by selecting a microwave-safe mug that holds at least 12 ounces. This gives the cake room to rise without overflowing. I learned this the hard way after cleaning my microwave several times!
Step 2: Melt the Butter Melt your butter in the mug itself for about 15 seconds. This saves you from washing an extra dish. Let it cool slightly so it doesn’t cook the egg when you add it.
Step 3: Add Wet Ingredients Crack your egg directly into the mug with the melted butter. Whisk everything together using a fork until completely smooth. Make sure there are no streaks of egg white remaining. This step is crucial for achieving an even texture.
Step 4: Mix Dry Ingredients Add the almond flour, erythritol, cocoa powder, and baking powder to the mug. Stir thoroughly until you have a smooth, lump-free batter. The batter should be thick but pourable, similar to brownie batter. Scrape down the sides to incorporate all the dry ingredients.
Step 5: Add Chocolate Chips Fold in most of the Lily’s chocolate chips, reserving a few for the top. Press the remaining chips gently into the surface of the batter. This creates a beautiful presentation and ensures chocolate in every bite.
Step 6: Microwave Cook on high power for 90 seconds to 2 minutes. Cooking time varies depending on your microwave’s wattage. The cake is done when the center is just set but still slightly glossy. Remember, it will continue cooking slightly after you remove it.
Step 7: Cool and Enjoy Let the mug cake cool for 2-3 minutes before eating. This allows it to set properly and prevents burnt tongues. The texture improves as it cools to a comfortable eating temperature.
Pro Tips for Perfect Results
Tip 1: Don’t Overcook Microwaves vary significantly in power levels. Start with 90 seconds and add time in 10-second intervals if needed. An overcooked mug cake becomes dry and rubbery. The center should look slightly underdone when you stop cooking.
Tip 2: Use Fresh Baking Powder Old baking powder won’t give you the rise you need. Test it by adding a pinch to hot water. It should bubble vigorously if it’s still good.
Tip 3: Measure Almond Flour Correctly Spoon the flour into your measuring cup and level it off. Packing it down will result in a dense, heavy cake. I weigh mine when possible for the most consistent results.
Tip 4: Customize Your Sweetness Everyone’s taste preferences differ. Start with the recipe as written and adjust from there. You can easily add an extra teaspoon of erythritol if you prefer sweeter desserts.
Flavor Variations
Try adding a pinch of espresso powder to intensify the chocolate flavor. Mix in a teaspoon of peanut butter for a chocolate-peanut butter version. Add a drop of vanilla extract for extra depth. Swap half the cocoa powder with strawberry powder for a different twist.
Storage, Nutrition & FAQs
Storage Instructions
This keto mug cake tastes best when eaten fresh and warm. However, you can store leftovers in an airtight container in the refrigerator. It will keep for up to 2 days, though the texture changes slightly. Reheat in the microwave for 15-20 seconds before serving.
I don’t recommend making this ahead and storing it. Part of the appeal is how quick and fresh it is. The ingredients are simple enough to whip up whenever the craving hits. Keep your pantry stocked and you’ll always be ready.

Frequently Asked Questions
Q1: Can I use coconut flour instead of almond flour? Coconut flour is much more absorbent than almond flour. If you substitute it, use only 1-2 tablespoons maximum. You may need to add an extra tablespoon of melted butter. The texture will be slightly different but still delicious.
Q2: What if I don’t have erythritol? You can substitute with monk fruit sweetener in equal amounts. Stevia works too, but use only 1/4 teaspoon as it’s much sweeter. Some people use allulose, which measures cup-for-cup like sugar. Avoid using regular sugar if you want to keep it keto.
Q3: Can I make this without a microwave? Absolutely, you can bake it in a preheated oven instead. Use a small ramekin and bake at 350°F for 12-15 minutes. The texture will be slightly different, more cake-like than fudgy. Check for doneness with a toothpick inserted in the center.
Q4: Why did my mug cake turn out rubbery? This usually happens from overcooking the cake. Reduce your cooking time by 15-30 seconds next time. Make sure you’re using a microwave-safe mug that allows even heating. The cake should be just set, not firm.
Q5: Can I double this recipe? You can double the ingredients, but use a larger mug or bowl. The cooking time will increase to about 3-4 minutes. Watch it carefully to prevent overflow during cooking. I prefer making individual servings for better texture control.
Final Thoughts
This keto mug cake has become my favorite solution for sweet cravings. It’s proof that eating low carb doesn’t mean giving up desserts. The rich chocolate flavor and fudgy texture rival any traditional cake. Best of all, you can have it ready in less than 10 minutes.
I encourage you to try this recipe and make it your own. Experiment with different flavors and toppings to find your favorite version. Share it with friends who think keto means deprivation. They’ll be amazed at how delicious healthy eating can be.
