Step-by-Step Instructions

1. 1.Combine Dry Ingredients

   In a microwave-safe mug, mix together the all-purpose flour, unsweetened cocoa powder, granulated sugar, baking powder, and a pinch of salt.

2. 2.Add Wet Ingredients

   To the dry ingredients in the mug, add the milk, vegetable oil (or melted butter), and vanilla extract.

3. 3.Add Food Coloring (Optional)

   If making a red velvet cake, add a few drops of red food coloring to the mixture. This step can be skipped for a chocolate mug cake.

4. 4.Mix Well

   Stir all the ingredients in the mug until the batter is smooth and well combined.

5. 5.Add Gooey Center

   Spoon 1 tablespoon of raspberry or strawberry jam into the center of the batter.

6. 6.Add Chocolate Chips

   Drop a few white chocolate chips (or a small piece of chocolate) directly on top of the jam. They will sink during cooking.

7. 7.Microwave

   Place the mug in the microwave and cook for 60 to 90 seconds. The cake should rise and appear set on top.

8. 8.Cool and Serve

   Let the mug cake cool for one minute. Then, top with whipped cream and Valentine's Day sprinkles before serving.
