Peel and dice one apple into small pieces. Place in a mug, add 1 tablespoon water and a pinch of cinnamon (optional). Cover with cling film and microwave at full power for 4-5 minutes. While cooking, rub together 1 knob of softened butter, 1 heaped tablespoon powdered sugar, and 1 tablespoon flour with your fingertips until it resembles coarse sand. Scatter over the hot apples and microwave for 1 more minute. A satisfying crumble fix in minutes!
In a mug, blend 4 tablespoons cream cheese (ricotta-style), 1 egg, 1 tablespoon lemon juice, and 2 tablespoons icing sugar. Microwave for 1-1.5 minutes, depending on desired firmness. Crush 2 shortbread or speculoos biscuits coarsely and sprinkle on top straight from the microwave for a creamy, crunchy treat.
This savory twist proves mug cakes aren't just for sweets. Whisk 1 egg with 1 tablespoon tomato sauce, 1 tablespoon olive oil, and a pinch of oregano. Stir in 5 tablespoons flour and a pinch of baking powder for a smooth batter. Fold in diced ham, cheese, and olive slices if desired. Microwave for 2 minutes. Pizza perfection, ready to devour!
