Ingredients

4 tbsp all-purpose flour
2 tbsp sugar
2 tbsp cocoa powder
1/8 tsp baking powder
3 tbsp milk
2 tbsp vegetable oil or melted butter
1/4 tsp vanilla extract
1 egg

Instructions

Step 1: In a microwave-safe mug, combine the flour, sugar, cocoa powder, and baking powder. Mix well to evenly distribute the dry ingredients.
Step 2: Add the milk, vegetable oil (or melted butter), vanilla extract, and egg to the mug. Stir thoroughly until you have a smooth batter without lumps.
Step 3: Microwave the mug on high for about 1 to 2 minutes. Cooking time may vary depending on your microwave’s wattage — the cake should rise and be set but still moist inside.
Step 4: Carefully remove the mug (it will be hot) and let the cake cool for a minute or two before enjoying directly from the mug or transferring to a plate.

Tips & Variations

For an extra indulgent touch, add a handful of chocolate chips or a spoonful of peanut butter to the batter before cooking.
Use almond or oat milk as a dairy-free alternative without changing the texture much.
If you prefer a fluffier cake, separate the egg, beat the white until stiff peaks form, then fold into the batter gently before microwaving.

Storage

Chocolate mug cake is best enjoyed fresh from the microwave. If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave for 15–20 seconds to warm through.

FAQs

Can I make this cake without an egg?

Yes, you can substitute the egg with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) or omit it; however, the texture may be less fluffy and more dense.

What if my cake turns out dry or rubbery?

Microwave wattages vary, so reduce the cooking time and check in 15-second increments next time. Overcooking leads to dryness, so aim for a moist, slightly undercooked center.
