Key Ingredients for the Best 3 Ingredient Mug Cake

ingredients to make 3 ingredient mug cake on a grey surface - nutella, cocoa powder, and an egg.

(Full ingredient list appears in the recipe card below)

This recipe centers on Nutella, which gives the cake its creamy, chocolate-hazelnut character. You’ll need just three items:

  • Nutella: The base of the cake—rich and creamy for a decadent bite.
  • Cocoa powder: Adds extra chocolate depth. If you prefer, you can substitute a tablespoon of all-purpose flour, but cocoa gives a more intense chocolate flavor.
  • Egg: Binds the batter and creates a soft, slightly gooey texture when microwaved.

How to Make Three-Ingredient Mug Cake

Follow these straightforward steps for a fast, delicious mug cake:

nutella and an egg in a mug mixed together with a fork.

Step 1: Use a large microwave-safe mug (or a small bowl). Mix the Nutella and egg with a fork or small whisk until fully combined, about 1 minute.

Step 2: Add the cocoa powder and whisk until smooth and lump-free. Microwave the mug for 45 seconds to 1 minute. The top should be set but still slightly soft—aim for a molten, gooey center rather than a dry cake.

Topping Ideas

Mug cakes are perfect for experimenting with toppings. Try any of these to elevate your treat:

  • Ice cream: A scoop of vanilla melting over the warm cake is heavenly; add fresh fruit for brightness.
  • Extra Nutella: Drizzle a little more on top for extra indulgence.
  • Whipped cream: A cloud of whipped cream and a few berries add texture and freshness.
  • Crushed Oreos: Sprinkle for a crunchy Oreo twist.
  • Chocolate chips: Any variety—milk, dark, peanut butter, or butterscotch—works well.

Think of the mug cake as a canvas—mix and match toppings to suit your cravings.

Pro Tips

  • Avoid overfilling: Fill the mug no more than halfway; the cake will rise while cooking.
  • Adjust the time: Microwave powers vary. Start with 45–60 seconds, then add 10-second increments if needed. The top should be set but slightly moist.
  • Mix thoroughly: Whisk until smooth so cocoa powder doesn’t leave lumps.
  • Use a wide mug: A wider, 12-ounce mug cooks more evenly. Narrow mugs can leave the center undercooked.
