1. Classic 5-Minute Chocolate Mug Cake

Ingredients:

• 4 tablespoons all-purpose flour
• 2 tablespoons cocoa powder
• 1/4 teaspoon baking powder
• 3 tablespoons granulated sugar
• 3 tablespoons milk (any kind)
• 2 tablespoons vegetable oil
• 1/4 teaspoon vanilla extract
• Pinch of salt

Instructions:
In a standard-sized mug, combine all dry ingredients and stir until well mixed. Add in the milk, oil, and vanilla extract. Stir until the batter is smooth and free of lumps. Microwave on high for 1 minute and 30 seconds. Let it sit for 30 seconds to cool before digging in. Optional: top with a scoop of ice cream or drizzle of chocolate syrup.

Health Benefits:
Portion-controlled and made with simple ingredients, this cake is perfect for satisfying a craving without overindulging.
