1/8 teaspoon salt

3 tablespoons milk (any kind)

2 tablespoons creamy or crunchy peanut butter

1 tablespoon vegetable oil

1/4 teaspoon pure vanilla extract

Instructions
 

Begin by selecting a microwave-safe mug, ideally 12 oz in size. In this mug, combine the all-purpose flour, granulated sugar, cocoa powder, baking powder, and salt. Using a fork, mix all the dry ingredients thoroughly until they are well incorporated.

    Pour in the milk, followed by the peanut butter, vegetable oil, and vanilla extract. Mix vigorously with a fork or small whisk until the batter becomes smooth and free of lumps. If you choose to add chocolate chips, fold them into the batter gently at this stage.

      Place the mug in the microwave and heat on high power for approximately 1 minute and 20 seconds. Keep an eye on the cake as it cooks, as microwave wattages can vary. The cake should rise and appear set, though it may still be slightly moist in the center.

        After microwaving, carefully remove the mug from the microwave (it may be hot), and let the cake cool for 1-2 minutes. This will allow it to set further, making it easier to enjoy.
