3 tablespoons (45ml) milk
-
4 tablespoons (30g) all-purpose flour

Step-by-Step Instructions
1. Prepare the Ramekin or Mug
Lightly grease a microwave-safe mug or small ramekin with butter or oil. Set aside.
2. Mix Wet Ingredients
In a small bowl, whisk together the egg, sugar, melted butter, milk, lemon juice, and vanilla until smooth.
3. Add Dry Ingredients
Sift in the flour, baking powder, and salt. Add the lemon zest. Mix gently until fully combined and smooth.
Tip: Don’t overmix—this keeps the cakes light and fluffy.
4. Microwave (Fast Method)
Pour the batter into your prepared mug or ramekin. Microwave on high for 90–120 seconds, checking at 90 seconds.
The cake should rise and be set but soft in the center. Cooking times vary by microwave, so adjust slightly if needed.
5. Optional Oven Method
If you prefer baking:
-
Preheat oven to 350°F (175°C).
-
Pour batter into a small greased ramekin.
-
Bake for 10–12 minutes, until a toothpick comes out clean.
6. Serve
Let cool for 1–2 minutes. Optionally dust with powdered sugar or drizzle with a simple lemon glaze (1 tablespoon lemon juice + 1 tablespoon powdered sugar). Enjoy straight from the mug or plate.

Frequently Asked Questions
Can I make more than one cake at a time?
Yes! Multiply ingredients for multiple ramekins, but microwave separately for even cooking.
Can I use sugar substitutes?
Yes, but adjust sweetness and texture. Powdered sugar alternatives melt best in the batter.
Why didn’t my cake rise?
Make sure your baking powder is fresh and don’t overmix the batter.
Can I use oil instead of butter?
Absolutely! Use the same amount. It will make the cake slightly moister.
