Make the Mug Cake

1. Mix the Dry Ingredients: In a microwave-safe mug, combine the flour, sugar, cocoa powder, baking powder, and salt. Stir to make sure everything is well-mixed.
2. Add the Wet Ingredients: Add the milk, vegetable oil, vanilla extract, and red food coloring. Stir the mixture together until it forms a smooth batter. Make sure to scrape the sides of the mug to incorporate all the ingredients.
3. Microwave: Microwave the mug cake on high for about 2 minutes. Keep an eye on it—if your microwave runs hot, you might need to reduce the time slightly. The cake should rise and set in the middle. If the top is still wet, microwave in 15-second increments until done.
4. Cool: Let the mug cake cool for a minute or two before topping it with frosting. Don’t worry—this won’t take long!

Make the Cream Cheese Frosting

1. Mix the Frosting: In a small bowl, whisk together the cream cheese, butter, powdered sugar, and vanilla extract. Stir until smooth and creamy. You can adjust the sweetness by adding more powdered sugar if desired.
2. Top the Cake: Spoon the frosting onto the mug cake, spreading it gently over the top. For a fun extra touch, you can even swirl it with a knife for a beautiful effect.
