Step 1

Add the flour, sugar, lemon zest, baking powder, baking soda, and salt to a microwave safe mug that holds at least 10 ounces. Mix the ingredients together with a fork.

Step 2

Pour the almond milk, lemon juice, oil, and vanilla extract into the mug. Mix everything together with a fork until well combined.

Step 3

Place the mug in the microwave. Microwave on high for 90 seconds, watching to make sure the mug does not overflow.

Step 4

Remove the mug from the microwave. The mug will be hot so be careful! Let the cake cool slightly. Add toppings like coconut cream or powdered sugar and enjoy.
