Ingredients

4 Tablespoons All-Purpose Flour

2 Tablespoons Organic Cane Sugar

1/4 tsp Baking Powder

Pinch of Salt

3 Tablespoons Oat Milk (or any plant-based milk)

1 Tablespoon Neutral Oil

1 Tablespoon Fresh Lemon Juice

This lemon mug cake is one of my favorite quick desserts because it tastes like spring in a mug. It’s soft, moist, and perfectly sweet with the natural zing of fresh lemon juice and zest. I love making this when I want something homemade but don’t want to spend time baking an entire cake.

Instructions

In a small mug, whisk together the flour, sugar, baking powder, and salt.

Add oat milk, oil, lemon juice, and zest. Stir until just combined — don’t overmix.

Microwave for 60–70 seconds, until the cake is set but still moist.

Cool slightly, dust with powdered sugar if desired, and enjoy warm!
