Grab a 12-oz microwave-safe mug and add ¼ cup of all-purpose flour and 2 tbsp of granulated sugar.

Pour ¼ cup of hot cocoa mix into the mug.

Sprinkle ¼ tsp of baking powder and ⅛ tsp of salt to help the cake rise and balance the flavors.

Use a small whisk to combine all the ingredients until well combined.

Start adding the wet ingredients by pouring 1/4 cup of Whole milk into the mug.

Stir in 2 tbsp of vegetable oil and ¼ tsp of vanilla extract.

Mix everything together thoroughly until the batter is smooth and no clumps of flour remain.

You can also mix the dark chocolate chips in if you prefer more chocolate flavor throughout the mug cake.

Pop the cake in the microwave and heat it for 60 seconds.

Use a toothpick to see the cake’s doneness. If the toothpick comes out clean with a few moist crumbs, the hot chocolate mug cake is done. If the batter is still liquid, it may require an additional 15 seconds.

Once cooked, carefully remove the mug from the microwave.

Let the cake cool for a few minutes before serving. The cake continues to set as it cools.

Top the cooled mug cake with freshly whipped cream, extra chocolate chips, mini marshmallows, or Nutella.

Sprinkle a little powdered sugar or cocoa powder for a finishing touch.

Serve and enjoy your warm, gooey hot chocolate mug cake.
