Description
This Sugar-Free Vanilla Mug Cake is a soft, fluffy, lightly sweet single-serving dessert that comes together in just a few minutes. Made with simple pantry ingredients and cooked in the microwave, it is perfect for late-night cravings, quick snacks, or whenever you want a warm homemade treat without baking an entire cake. Customize it with sugar-free sprinkles, berries, whipped topping, or Greek yogurt for an easy dessert.
Ingredients
Scale
- 1/4 cup all-purpose flour
- 1–2 tablespoons granulated sugar-free sweetener, preferably baking-friendly
- 1/4 teaspoon baking powder
- Pinch of salt
- 2 tablespoons milk or unsweetened almond milk
- 1 tablespoon unsalted butter, melted
- 1/2 teaspoon vanilla extract
- 1 tablespoon sugar-free sprinkles, optional
Instructions
- Choose a microwave-safe mug that holds at least 8 ounces. Lightly grease the inside with butter or cooking spray.
- Add the flour, sugar-free sweetener, baking powder, and salt to the mug. Stir until evenly combined.
- Add the milk, melted butter, and vanilla extract. Mix thoroughly with a fork, scraping the bottom and sides of the mug until no dry flour remains.
- Gently fold in the sugar-free sprinkles, if using.
- Microwave on high for 60–90 seconds. Start with 60 seconds and check the cake. If the center is still wet, continue cooking in 10-second intervals until the top is set and the center is soft but no longer wet.
- Let the mug cake rest for 1 minute before serving.
- Serve warm with sugar-free whipped topping, fresh berries, Greek yogurt, or your favorite sugar-free toppings, if desired.
Notes
- Use a wide mug when possible for more even cooking and to give the cake room to rise.
- Start with 60 seconds in the microwave and add time gradually. Overcooking can make the cake dry or rubbery.
- Allulose, monk fruit blends, erythritol blends, or another granulated baking sweetener can be used. Sweetness may vary by brand.
- Regular sugar can replace the sugar-free sweetener in the same amount, but the recipe will no longer be sugar-free.
- For a cinnamon-vanilla version, add a pinch of cinnamon to the dry ingredients.
- Add fresh blueberries, raspberries, or chopped strawberries for a fruity variation.
- Add sugar-free chocolate chips for a vanilla chocolate-chip mug cake.
- For a dairy-free version, use unsweetened almond milk and dairy-free butter.
- Sugar-free does not necessarily mean low-carb because this recipe uses all-purpose flour.
- Nutrition is approximate and can vary depending on the flour, milk, butter, sweetener, and toppings used.
