Begin by taking a microwave-safe mug and adding the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, and salt. Whisk the mixture thoroughly until all dry ingredients are well combined and free of lumps.
Pour in the milk and vegetable oil into the dry mixture. Use a fork or whisk to mix until the batter is smooth and uniform, ensuring there are no lumps remaining.
Next, add the peppermint extract to the batter, followed by mini chocolate chips if you choose to use them. Stir to ensure all ingredients are integrated evenly for that perfect burst of flavor in every bite.
Place the mug in the microwave and cook on high for 1 minute and 30 seconds. After this time, check the cake’s doneness; it should be set in the center. If it still appears wet, continue to microwave in 10-second intervals until fully cooked through.
Once cooked, remove the mug from the microwave (be cautious of the heat!) and allow the cake to cool for about a minute. Finally, to elevate the festive appeal, generously top your mug cake with whipped cream and finish with a sprinkle of crushed candy canes for a delightful peppermint crunch.
