Why You'll Love This Recipe
About the Ingredients
4 tablespoons (30g) all-purpose flour
Standard all-purpose flour works best. For a gluten-free option, use a 1:1 gluten-free flour blend.
3 tablespoons (40g) granulated sugar
Regular white sugar gives the best texture. You can reduce to 2 tablespoons for a less sweet cake.
1/4 teaspoon baking powder
This is the leavening agent that makes the cake rise. Make sure it's fresh for best results.
1/8 teaspoon salt
A pinch of salt enhances the sweetness and balances the flavors.
3 tablespoons (45ml) milk
Any milk works – dairy, almond, oat, or soy. The fat content affects richness; whole milk gives a richer taste.
2 tablespoons (28g) unsalted butter, melted
Melted butter adds moisture and flavor. You can substitute with coconut oil or vegetable oil.
1/2 teaspoon vanilla extract
Pure vanilla extract gives the best flavor. You can use vanilla bean paste or a pinch of vanilla powder if you have it.
Tips & Tricks
- Use a standard 12-ounce (350ml) microwave-safe mug. If it's too small, the cake will overflow.
- Mix the dry ingredients first to ensure even distribution of baking powder and salt.
- Don't overmix! Stir just until the batter is smooth – overmixing can make the cake tough.
- Microwave times vary. Start with 90 seconds, then add 10-second increments until done.
Pro Tips
Step-by-Step Instructions
1. Mix dry ingredients
In a microwave-safe mug, whisk together the flour, sugar, baking powder, and salt until well combined. This ensures the leavening agent is evenly distributed.
2. Add wet ingredients
Add the milk, melted butter, and vanilla extract to the mug. Stir gently with a fork or small whisk until just combined. Be careful not to overmix – a few lumps are okay.
3. Rest the batter
Let the batter sit for 1 minute. This allows the baking powder to start working, which helps create a lighter, fluffier cake.
4. Microwave the cake
Place the mug on a microwave-safe plate and microwave on high for 90 seconds at 100% power (or 1000W). The cake should rise and set. If it's still wet on top, microwave in 10-second increments until done.
5. Check for doneness
The cake is done when the top is dry to the touch and springs back when lightly pressed, or a toothpick inserted into the center comes out clean. Be careful not to overcook, or it will become rubbery.
6. Cool and serve
Let the mug cake cool for 1-2 minutes before enjoying. It's delicious warm, straight from the mug, or you can transfer it to a plate. Top with your favorite toppings if desired.
Delicious Variations
Chocolate Chip
Fold 1 tablespoon of chocolate chips into the batter before microwaving.
Berry Burst
Gently fold in 1 tablespoon of fresh or frozen blueberries or raspberries.
Spiced Vanilla
Add 1/4 teaspoon of cinnamon and a pinch of nutmeg to the dry ingredients for a warm, cozy flavor.
How to Store Vanilla Mug Cake Easy
Refrigerator
This mug cake is best enjoyed immediately. If you have leftovers, you can store them in an airtight container in the fridge for up to 1 day, but the texture will be less ideal.
Freezer
Freezing is not recommended as the texture will become soggy upon thawing.
Reheating
To reheat a leftover mug cake, microwave it for 15-20 seconds until warm. It won't be as fluffy as fresh, but it's still tasty.
Frequently Asked Questions
Q: Can I make this vanilla mug cake without eggs?
Yes, this recipe is eggless! It uses baking powder as the leavening agent, so you don't need eggs for the cake to rise and set.
Q: Why is my mug cake rubbery or tough?
A rubbery mug cake is usually the result of overmixing or overcooking. Mix just until the ingredients are combined, and microwave for the shortest time possible, adding seconds only if needed.
Q: Can I use self-rising flour instead of all-purpose?
Yes, you can. If using self-rising flour, omit the baking powder and salt, as they are already included in the flour.
Q: Can I double this recipe?
Yes, you can double the ingredients and split the batter between two mugs. Microwave each mug separately for best results, as cooking times may vary.
Q: What can I use instead of butter?
You can substitute the butter with an equal amount of coconut oil, vegetable oil, or even applesauce for a lower-fat option. The texture may vary slightly.
Now that you've mastered this mug cake, why not try swapping the vanilla for a splash of almond or peppermint extract? Small changes can lead to delicious discoveries. Here's to small steps, together.
