Forget everything you know about baking. No heavy flour, no preheating the oven for an hour, and no mountain of dishes. This recipe is for those late-night cravings when you want something that tastes like a fancy molten lava cake but only have five minutes to spare. By skipping the flour, we lean into the hazelnut goodness of the Nutella and the lift from a single egg to create a rich, fudgy, souffle-style dessert.

Ingredients

  • Nutella (or hazelnut spread): 2½ tablespoons
  • Large Egg: 1 (room temperature is best for a smooth mix)
  • Granulated Sugar: 1 to 2 teaspoons
  • Unsweetened Cocoa Powder: 1 tablespoon (Dutch-processed for a darker color)
  • Vanilla Extract: ½ teaspoon
  • Sea Salt: A tiny pinch

Instructions

  1. Whisk the Batter: In a small bowl, crack the egg and give it a quick whisk. Stir in the Nutella, sugar, cocoa, vanilla, and salt. Keep mixing until it’s completely glossy and you don’t see any yellow egg streaks.
  2. Prep the Mug: Pour your chocolate mixture into a microwave-safe mug (12oz is perfect). It should only fill about half the mug.
  3. The Zap: Microwave on high for 60 to 75 seconds. Watch it closely! It will puff up high and then settle back down.
  4. The Rest: Let it sit for 2 to 3 minutes. This is the secret to the perfect texture—it lets the center set so it’s fudgy, not liquid.

Notes

Serving Suggestions:

  • The Classic: Top with a big scoop of vanilla ice cream or whipped cream.
  • The Fancy: Sprinkle with extra sea salt and crushed hazelnuts.
  • The “Surprise”: Push a square of dark chocolate or a teaspoon of peanut butter into the center before microwaving.

Tips & Tricks:

  • Check the mug: Use a wide mug rather than a tall, narrow one for even cooking.
  • Don’t overbake: If it looks slightly damp in the very center when you take it out, that’s good! It will finish cooking as it rests.
  • Egg Temp: If your egg is cold, the Nutella might seize up. If that happens, zap the mixture for 5-10 seconds to loosen it.

Storage & Reheating:

  • Fresh is best: Mug cakes are meant to be eaten immediately.
  • Leftovers: If you have to wait, cover with wrap at room temperature for up to 24 hours. Reheat for 10 seconds to bring back the gooeyness.
