Step 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.

Step 2: Add Wet Ingredients

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

Step 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.

Step 4: Mix Well

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

Step 5: Add Gooey Center

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

Step 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.

Step 7: Microwave

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

Step 8: Cool and Serve

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

• Store covered in the fridge for up to 1 day.

• Freeze for longer storage.

• Reheat gently in the microwave before serving.

• Skip red food coloring for a chocolate mug cake.

• Use raspberry or strawberry jam for the gooey center.

• Use a small piece of chocolate instead of white chocolate chips.
