Ingredients
  

The Dry Base

  • 4 tbsp All-purpose flour
  • 3 tbsp Granulated sugar
  • 2 tbsp Unsweetened cocoa powder
  • 1/4 tsp Baking powder
  • 1 pinch Salt

The Liquids

  • 3 tbsp Water
  • 2 tbsp Neutral oil vegetable or canola
  • 1/4 tsp Vanilla extract

The Gooey Factor

  • 1 tbsp Chocolate chips dark or milk

Instructions
 

  • Grab your favorite microwave-safe mug (the bigger, the better!) and whisk together the flour, sugar, cocoa powder, baking powder, and salt with a fork until no lumps remain.
  • Add the water, neutral oil, and vanilla extract directly into the mug with the dry ingredients.
  • Stir the mixture vigorously with your fork, making sure to scrape the bottom edges of the mug until the batter is smooth and glossy.
  • Drop the chocolate chips into the center of the batter and push them down slightly so they are submerged.
  • Place the mug in the center of your microwave and cook on high for 60 to 75 seconds.
  • Watch the cake through the window; it should rise up high and then settle slightly as the timer ends.
  • Carefully remove the mug (it will be hot!) and let it sit on the counter for 60 seconds to firm up.
  • Grab a spoon and enjoy your warm chocolate fix immediately while the center is still melty and gooey.

Notes

Tips: For a "Mexican Chocolate" twist, add a tiny pinch of cinnamon and cayenne pepper to the dry mix.
Substitutions: You can use milk or coffee instead of water for a richer flavor profile.
Storage: This is best eaten immediately, but you can store the dry mix in jars for an "instant" mug cake kit!
