Step‑by‑Step Instructions for Lemon Mug Cake

Step 1: Prepare Mixing Bowl
Start by grabbing a medium mixing bowl and combine your chosen flour, sugar, baking powder, and a pinch of salt. Whisk these dry ingredients together until well blended, ensuring no lumps remain. This step sets the foundation for your fluffy lemon mug cake, delivering the perfect texture.

Step 2: Add Liquids
Next, stir in the essential wet ingredients: water, fresh lemon juice, melted butter or a healthy alternative, lemon zest, and pure vanilla extract. Mix everything together until you achieve a smooth batter. The zesty aroma should start to fill the air, creating anticipation for that delightful lemon mug cake!

Step 3: Transfer to Mug
Now, take a coffee mug or a large ramekin and lightly grease it to prevent sticking. Pour the prepared batter into the mug, filling it about halfway to allow for rising during cooking. This will ensure that your lemon mug cake bakes beautifully and retains its fluffy texture.

Step 4: Bake
For the final step, cook your lemon mug cake in a preheated microwave for about 1.5 to 2 minutes. Alternatively, you can bake it in an oven set to 350°F for about 10 minutes. Keep an eye on it; once a toothpick inserted into the center comes out mostly clean, you know your cake is ready to enjoy!

How to Store and Freeze Lemon Mug Cake

Fridge: Enjoy your lemon mug cake fresh, but if you have leftovers, it can be stored in the fridge for up to 1 day. Place it in an airtight container to maintain moisture.

Freezer: Freeze any leftover cake in an airtight container for up to 1 month. Just make sure it’s cooled completely before sealing.

Reheating: To savor your lemon mug cake again, microwave it for 10-20 seconds or until warmed through. This quick method helps restore its fluffy texture.

Enjoy Fresh: For the best taste and texture, it’s always ideal to indulge in your lemon mug cake right after baking!

Expert Tips for Lemon Mug Cake

Check Timing: Microwave wattages vary, so start with 1.5 minutes and adjust as necessary to avoid overcooking, which leads to dryness.
Zest Matters: Incorporate fresh lemon zest; it brightens flavor significantly. Skip it, and you miss that zesty spark!
Ingredient Quality: Use fresh lemon juice for the best flavor. Bottled juice lacks the freshness and vibrancy of a whole lemon.
Grease Well: Don’t forget to grease your mug or ramekin; this prevents sticking and ensures a clean removal for your fluffy lemon mug cake.
Double Up: If you’re feeling indulgent, consider making two cakes! Store one in the fridge, but enjoy the first warm right away!

Make Ahead Options

These Lemon Mug Cakes are perfect for meal prep enthusiasts! You can prepare the dry ingredients—flour, sugar, baking powder, and salt—up to 24 hours in advance. Simply mix them in a bowl and store in an airtight container to maintain freshness. The wet ingredients, such as lemon juice, lemon zest, and melted butter/oil, can also be combined and kept in the refrigerator for up to 3 days, ensuring a quick assembly later. When you’re ready to enjoy your fluffy lemon mug cake, just combine the wet and dry mixtures, transfer to a mug, and microwave or bake as directed. You’ll have a delightful treat with minimal effort, just as delicious as if made from scratch!
