  • Adjustable for dietary needs: Easily modify for dairy-free or healthier options.
  • Deliciously rich and fudgy: Every bite is a decadent delight.

Ingredients

Gather these simple ingredients to create your irresistible chocolate mug cake:

  • 3 Tbsp all-purpose flour (23 g)
  • 2 Tbsp granulated sugar (25 g)
  • 1 Tbsp unsweetened cocoa powder (7.5 g)
  • ¼ teaspoon baking powder (1 g)

    Understanding the science of leavening agents like baking powder is key to achieving a light and fluffy texture in cakes, as detailed in articles on the role of baking powder in the cake baking industry.

  • Dash salt (0.5 g)
  • 3 tablespoons milk (any kind of milk) (45 ml)
  • 1 tablespoons canola oil (or melted butter) (15 ml)
  • 1/8 teaspoon vanilla extract (0.6 ml)
  • 1 tsp chocolate chips, or your favorite flavor baking chips (5 g)

Notes & Substitutions

You can easily adapt this quick chocolate dessert recipe to fit your preferences or what you have on hand.

  • Flour: Use standard all-purpose flour or substitute with white whole wheat flour for a subtle nutty flavor.
  • Sweetener: Granulated sugar works best. For a healthier option, halve the sugar amount.
  • Fat: Canola oil provides a neutral flavor, but melted butter, applesauce, or melted coconut oil are great alternatives. Research indicates that substituting fats like clarified butter with canola oil can positively impact nutritional profiles.
  • Milk: Any type of milk works here, including dairy milk, almond milk, or soy milk for a dairy-free option.
  • Chocolate Chips: Feel free to use any favorite baking chips, such as dark chocolate, milk chocolate, or white chocolate.

Equipment

You only need a few basic kitchen items to whip up this easy treat.

  • Microwave-safe mug (12-16 oz)
  • Small whisk or fork
  • Measuring spoons
  • Cooking spray

Instructions For The Best Chocolate Mug Cake

Creating your perfect chocolate mug cake is incredibly straightforward. Follow these steps for a delicious, warm dessert.

  1. Lightly spray the bottom of a microwave-safe mug or coffee cup with cooking spray. This helps prevent sticking and makes cleanup easy.
  2. Add the dry ingredients directly into the prepared mug: flour, sugar, unsweetened cocoa powder, baking powder, and a dash of salt.
  3. Stir these dry ingredients together thoroughly with a small whisk or fork until they are well combined.
  4. Next, pour in the wet ingredients: milk, canola oil, and vanilla extract.
  5. Stir everything together until the batter is smooth and no dry pockets of flour remain. Make sure to scrape the bottom of the mug as you mix.
  6. Gently stir in the chocolate chips, or sprinkle them on top of the batter if you prefer.
  7. Place the mug in the microwave and cook for 70-90 seconds. Cooking time may vary based on your microwave’s wattage.
  8. The cake is done when it looks just set but still has a slightly shiny appearance on top.
  9. Once cooked, allow the chocolate treat to rest in the microwave for 1 minute before carefully removing it.
  10. Serve your delightful creation warm with your desired toppings.

Pro Tips for the Perfect Mug Cake

Getting the perfect texture for your chocolate mug cake is easy with these simple tips.

  • Microwave Power: Microwave wattages vary. Start with 70 seconds for your first mug cake, then add 10-second increments if needed.
  • Avoid Overcooking: Overcooking leads to a dry cake. Remove it when it looks just set and slightly shiny on top for a moist, fudgy texture.
  • Mug Size: Use a 12-16 oz mug to prevent the batter from overflowing during cooking. This size allows proper rise.
  • Thorough Mixing: Ensure you scrape the bottom of the mug well while mixing. This prevents pockets of unmixed dry ingredients.
  • Resting Time: Allowing the cake to rest in the microwave for 1 minute after cooking is crucial. This helps it finish setting and improves its overall texture.

Serving, Storage & Variations

Once your delicious chocolate mug cake is ready, you can enjoy it in many ways. You also have options for storage and exciting flavor twists.

Serving Suggestions

Enjoy your warm, fudgy treat straight from the mug for ultimate comfort. Elevate the experience by adding a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of chocolate sauce. A sprinkle of powdered sugar or fresh berries adds a touch of elegance.

Storage Instructions

This quick chocolate dessert is always best enjoyed immediately while warm. If you happen to have any leftovers, cover the mug tightly and store it at room temperature for a very short period. Reheating it briefly in the microwave can refresh the texture.

Flavor Variations

Get creative with your single-serving chocolate mug cake:

  • Added Swirls: Swirl in a tablespoon of Nutella or peanut butter into the batter before microwaving for an extra layer of flavor.
  • Extra Texture: Mix in chopped nuts like walnuts or pecans, or add shredded coconut flakes for a delightful crunch.
  • Spice It Up: A pinch of cinnamon or a dash of instant espresso powder can deepen the chocolate flavor beautifully.
  • Dairy-Free: Use almond or soy milk, dairy-free butter or oil, and dairy-free chocolate chips for a delicious vegan option.
  • Healthier Options: Refer to the “Notes & Substitutions” section for tips on reducing sugar or swapping fats for lighter alternatives.
