1-Prepare the mug and mix dry ingredients: First, gather all your ingredients and lightly spray the bottom of a microwave-safe mug with cooking spray to prevent sticking. This helps the cake release easily and keeps the texture just right. In the mug, add the flour, sugar, cocoa powder, baking powder, and salt; stir them together until well mixed.

2-Add wet ingredients and stir smoothly: Next, pour in the milk, oil or melted butter, and vanilla extract; stir until the batter is smooth, making sure to scrape the bottom of the mug. For the best results, mix gently to avoid overworking the batter.

3-Incorporate chocolate chips: Then, stir in the chocolate chips or sprinkle them on top for a gooey surprise.

4-Microwave and let it rest: Finally, microwave on high for 70 to 90 seconds until the cake is just set but still slightly shiny on top. Let it rest in the microwave for 1 minute to finish cooking and stay soft inside. Remember, microwave power varies, so start with 70 seconds and add 15 to 25 seconds if needed it’s all about checking as you go. Once ready, enjoy it as is or add toppings like fresh fruit for a personal touch.
