1. The Master Base Recipe

Before we get to the flavors, here is the foundation for every mug cake you'll make today.

IngredientAmount
All-purpose flour4 tbsp
Sugar (Granulated)2 tbsp
Baking powder1/4 tsp
Milk (any kind)3 tbsp
Vegetable oil or melted butter1 tbsp
Vanilla extract1/4 tsp

2. Choose Your Flavor

Now, let’s customize! Add these specific ingredients to your base mix:

Option A: Rich Chocolate

The ultimate comfort food. To the base, add:

  • 1 tbsp unsweetened cocoa powder

  • 1 tbsp chocolate chips (optional but highly recommended)

Option B: Classic Vanilla Bean

Simple, elegant, and perfect with a scoop of ice cream. To the base, add:

  • An extra 1/4 tsp vanilla extract (or vanilla bean paste)

  • A pinch of salt to enhance the sweetness

Option C: Birthday Party Funfetti

Because sprinkles make everything better. To the base, add:

  • 1 tbsp colorful sprinkles

  • Optional: A drop of almond extract for that "bakery" taste


3. Step-by-Step Instructions

  1. Mix Dry Ingredients: In a microwave-safe mug (at least 12 oz), whisk together the flour, sugar, baking powder, and your chosen flavor powder (like cocoa).

  2. Add Wet Ingredients: Stir in the milk, oil, and vanilla until the batter is smooth. Fold in your mix-ins (chips or sprinkles).

  3. Microwave: Cook on high for 70 to 90 seconds.

    Pro Tip: Every microwave is different. Start with 70 seconds. If the top looks wet, add 10-second intervals.

  4. Cool and Enjoy: Let it sit for 1 minute. This is crucial—it allows the structure to set so you don't burn your tongue!


Tips for the Perfect Mug Cake

  • Don't Overmix: Stir until just combined to keep the cake fluffy.

  • Use a Straight-Walled Mug: This helps the cake rise evenly.

  • Toppings Matter: Top your chocolate cake with peanut butter, your vanilla cake with berries, or your funfetti cake with whipped cream.


Frequently Asked Questions (FAQs)

Can I make this gluten-free?

Yes! You can swap the all-purpose flour for a 1:1 gluten-free flour blend.

Can I make it vegan?

Absolutely. Use almond, soy, or oat milk and ensure your oil or "butter" is plant-based.

Why is my mug cake rubbery?

Usually, this happens if you overcook it or use an egg in such a small portion. Our eggless recipe helps prevent this!
