What is a Mug Cake?
A mug cake is exactly what it sounds like: a cake that’s made in a mug and cooked in the microwave. These single-serve desserts are perfect for portion control, quick cravings, and late-night snacks. The concept has become wildly popular due to its simplicity and minimal cleanup. In less than five minutes, you can have a warm, fluffy cake that satisfies your sweet tooth.
The Lemon Lava Mug Cake with Condensed Milk takes the concept a step further by adding a lava center—a gooey core of sweetened condensed milk that adds richness and surprise to every spoonful.
Why You’ll Love Lemon Lava Mug Cake with Condensed Milk
This mug cake isn’t just about convenience. It offers a perfect balance of flavors and textures:
- Quick and Easy: No mixer, no oven, no problem. Just a mug, a spoon, and a microwave.
- Minimal Ingredients: You probably already have most of these ingredients in your kitchen.
- Zesty Flavor: Fresh lemon zest and juice provide a burst of citrus brightness.
- Molten Center: The sweetened condensed milk in the center melts into a lava-like core.
- Perfect for One: This is a single-serve dessert, which makes it ideal for portion control or solo indulgence.
Ingredients You’ll Need
Here’s everything you need to make this citrusy lava cake in a mug:
- 1/4 cup all-purpose flour
- 1/2 teaspoon baking powder
- 2 tablespoons granulated sugar
- 1 tablespoon lemon zest
- 2 tablespoons fresh lemon juice
- 2 tablespoons milk
- 1 tablespoon vegetable oil
- 1 tablespoon sweetened condensed milk (plus 1-2 teaspoons extra for the lava center)
- Pinch of salt
- Optional toppings: powdered sugar or whipped cream
Step-by-Step Instructions
Step 1: Mix the Dry Ingredients
In a microwave-safe mug (10 to 12 oz recommended), combine the flour, baking powder, sugar, lemon zest, and a pinch of salt. Stir well to ensure even distribution.
Step 2: Add the Wet Ingredients
Add the lemon juice, milk, vegetable oil, and 1 tablespoon of sweetened condensed milk to the dry mix. Stir until smooth. Make sure there are no lumps or dry pockets.
Step 3: Create the Lava Center
Drop 1 to 2 teaspoons of extra sweetened condensed milk right into the center of the batter. Do not stir it in. This will sink and form the lava core when cooked.
Step 4: Microwave the Cake
Place the mug in the microwave and cook on high for 45 to 55 seconds. The top should be set, and the cake should rise slightly. It should still feel soft in the center.
Step 5: Let It Rest
Allow the mug cake to cool for 1 to 2 minutes. This lets the lava center settle and thicken slightly, making for a more indulgent experience.
Step 6: Add Toppings and Serve
Top your mug cake with powdered sugar or whipped cream for extra flair and flavor. Serve warm and enjoy!
Tips for Success
- Use Fresh Lemons: Fresh lemon juice and zest provide much more flavor than bottled lemon juice.
- Microwave Wattage Matters: If your microwave is low wattage, you might need to add 5-10 seconds to the cooking time. If it’s high wattage, err on the side of caution to avoid overcooking.
- Do Not Overmix: Stir just until combined to avoid a tough or rubbery texture.
- Watch the Cake: Microwaves vary, so keep an eye on the cake the first time you make it.
- Check the Center: A slightly soft center is perfect. The residual heat will finish the cooking.
Variations and Add-ins
One of the best things about mug cakes is their flexibility. Here are a few variations you can try:
- Lemon-Blueberry: Fold in a few fresh or frozen blueberries before microwaving.
- Lemon Poppy Seed: Add a pinch of poppy seeds to the batter for texture and flavor.
- Lemon Curd Lava: Swap the condensed milk for lemon curd for a more tart core.
- Coconut Twist: Add a bit of shredded coconut to the batter and top with toasted coconut flakes.
- Cream Cheese Swirl: Drop in a spoonful of sweetened cream cheese instead of condensed milk for a cheesecake-like center.
