Grab a microwave-safe mug.
Use a regular coffee mug, not a tiny espresso cup. Trust me, overflow is not the vibe.
Add the Nutella.
Spoon about 4 tablespoons of Nutella into the mug. Eyeballing works here. We’re not baking for a competition.
Crack in the egg.
Add 1 egg straight into the mug. Break the yolk and stir until smooth. Yes, it will look weird at first—keep going.
Stir in the flour.
Add 2 tablespoons of flour and mix until fully combined. No dry pockets allowed. The batter should look thick and glossy.
Microwave it.
Cook on high for 45–60 seconds. Start with 45. The center should look just set but still soft. Overcooking is the enemy here.
Let it rest (briefly).
Give it about 30 seconds to cool unless you enjoy burning your tongue. I’ve been there. Regrets were made.
Grab a spoon and dig in.
No plates required. Zero judgment if you eat it straight from the mug.
