Servings & Timing:
- Servings: 1 mug cake
- Prep Time: 5 minutes
- Cook Time: 1 minute (microwave)
- Total Time: 6 minutes
Ingredients List:
For the Mug Cake:
- 1 tablespoon butter (grass-fed or organic is ideal)
- 2 tablespoons full-fat cream cheese (softened, this adds moisture and richness)
- 2 tablespoons coconut flour (a gluten-free, low-carb flour alternative)
- 1 tablespoon sweetener (such as erythritol, stevia, or monk fruit)
- 1 teaspoon vanilla extract (for that classic cake flavor)
- 1/4 teaspoon baking powder (to make the cake rise and create a light texture)
- 1 egg (for structure and protein)
- About a dozen blueberries (fresh or frozen, adding a burst of sweetness and nutrients)
Instructions:
1. Prepare the Mug:
- Start by selecting a microwave-safe mug. A 10-12 oz mug is ideal for this recipe. Ensure the mug is large enough to accommodate the rise of the batter without spilling over.
2. Softening the Butter & Cream Cheese:
- Add 1 tablespoon of butter and 2 tablespoons of full-fat cream cheese to the mug. Place the mug in the microwave for 20 seconds to soften the ingredients. This helps them blend easily into the batter.
- Pro Tip: If you’re using frozen cream cheese, make sure to soften it before starting the recipe. Cold cream cheese will not blend properly.
3. Adding Dry Ingredients:
- Add 2 tablespoons of coconut flour into the mug. Coconut flour absorbs liquid, so it’s essential to make sure the ratios are right.
- Add 1 tablespoon of your preferred sweetener. If you’re using a sugar substitute like erythritol or stevia, adjust to your sweetness preference.
- Stir in 1/4 teaspoon of baking powder. This will help the cake rise and give it a light texture.
- Pro Tip: You can substitute coconut flour with almond flour, but the ratios will change. Almond flour tends to be denser, so you may need more liquid.
4. Adding the Wet Ingredients:
- Crack 1 egg into the mug. The egg binds the ingredients together and provides structure to the cake.
- 1 teaspoon vanilla extract adds that aromatic sweetness that compliments the berries.
5. Mixing the Batter:
- Use a spoon or small whisk to thoroughly mix the ingredients. Scrape down the sides of the mug to ensure all ingredients are well combined.
- Pro Tip: If the mixture seems too thick, you can add a tiny splash of water or almond milk to loosen it up. Aim for a thick batter, but it should be scoopable and not overly stiff.
6. Folding in the Blueberries:
- Gently fold in about a dozen fresh or frozen blueberries. Fresh berries provide a natural burst of sweetness and color, but if you’re using frozen blueberries, don’t thaw them beforehand to avoid excess moisture in the batter.
7. Microwaving the Cake:
- Place the mug into the microwave and cook on high for 1 minute. The cooking time may vary depending on your microwave’s wattage. After 1 minute, check for doneness. The cake should have risen and firmed up slightly.
- Pro Tip: If the center still seems slightly runny, microwave in additional 10-second increments, checking each time to ensure it doesn’t overcook.
8. Let it Cool:
- Allow the mug cake to cool for 5 minutes before eating. This helps the flavors settle, and the texture improves as it cools. This is a crucial step if you want to avoid burning your mouth and fully experience the cake’s texture.
9. Enjoying the Cake:
- After cooling, you can enjoy your keto-friendly, delicious vanilla blueberry mug cake straight from the mug or transfer it onto a plate. The texture should be soft, moist, and slightly crumbly. The blueberries should burst in your mouth, providing natural sweetness.

Additional Notes:
For a Dairy-Free Version:
- If you prefer a dairy-free option, you can replace the cream cheese with dairy-free cream cheese and use a non-dairy butter substitute (like coconut oil or vegan butter).
For a Vegan Option:
- Substitute the egg with flaxseed meal (1 tablespoon flaxseed meal mixed with 3 tablespoons water as an egg replacer). This will provide structure and moisture.
For Extra Fluff:
- If you want your mug cake to be lighter and fluffier, you can whisk the egg whites separately before adding them to the batter. This will create more air in the batter and result in a fluffier texture.
Flavor Variations & Toppings:
-
Lemon Zest & Poppy Seed Cake:
- Add 1/2 teaspoon of lemon zest for a refreshing citrus flavor. You can also sprinkle in some poppy seeds for texture.
-
Chocolate Chip Version:
- Add 1 tablespoon of sugar-free chocolate chips to the batter for a chocolatey twist. The chocolate will melt inside the mug, adding richness to the texture.
-
Toppings:
- Top the mug cake with whipped cream, Greek yogurt, or a sprinkle of unsweetened shredded coconut for added creaminess and flavor.
-
Cinnamon Swirl:
- Add 1/4 teaspoon of cinnamon to the batter, and swirl it into the cake before microwaving for a cinnamon roll-inspired twist.
-
Almond Joy Inspired:
- Fold in a handful of chopped almonds and a tablespoon of unsweetened shredded coconut for an almond joy flavor.
Storage & Make-Ahead Tips:
How to Store Leftovers:
- While this mug cake is best enjoyed fresh, you can store leftovers in an airtight container at room temperature for up to 1 day. If you’d like to keep it longer, refrigerate it for up to 3 days. However, the texture may change upon reheating.
How to Reheat:
- To reheat, microwave the leftover mug cake for 10-15 seconds. If the cake has become too dry, you can drizzle a bit of almond milk or a dollop of yogurt on top to rehydrate it.
FAQs:
1. Can I use almond flour instead of coconut flour?
Yes, you can substitute coconut flour with almond flour, but the ratio will change. Almond flour is less absorbent, so you may need to use more almond flour (about 1/4 to 1/2 cup) and add more liquid to adjust the batter’s consistency.
2. Can I make this recipe without an egg?
Yes, you can substitute the egg with flaxseed meal (1 tablespoon flaxseed meal + 3 tablespoons water) or a chia egg for a vegan version. It will change the texture slightly, but it will still work.
3. How do I make this cake sweeter without adding sugar?
You can increase the amount of sweetener (such as stevia or erythritol) to your taste. Adding extra vanilla extract also helps to give the perception of sweetness.
