Chocolate Mug Cake Recipe

Ingredients:

• 4 tablespoons all-purpose flour
• 4 tablespoons sugar
• 2 tablespoons cocoa powder
• 1/8 teaspoon baking powder
• 1/8 teaspoon salt
• 3 tablespoons milk
• 2 tablespoons vegetable oil (or melted butter)
• 1/4 teaspoon vanilla extract
• Optional: Chocolate chips or chopped chocolate

Instructions:

1. Mix Dry Ingredients:

In a microwave-safe mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt.

2. Add Wet Ingredients:

Add the milk, vegetable oil (or melted butter), and vanilla extract. Stir until smooth.

3. Add Chocolate (Optional):

Stir in chocolate chips or pieces of chopped chocolate if you'd like extra gooey goodness!

4. Microwave:

Microwave the mug on high for 1 minute and 20 seconds. The cake should rise and set, but still be slightly moist in the center. (Microwave times may vary, so adjust accordingly.)

5. Serve:

Let the mug cake cool for a few minutes, then enjoy! You can top it with whipped cream, ice cream, or more chocolate chips for extra indulgence.
