2 Ingredient Nutella Mug Cake: Rich Treat in 5 Minutes

Q: Why does my Nutella mug cake taste eggy?

If your 2 ingredient Nutella mug cake has an eggy aftertaste, it’s likely from under-mixing or eating it too soon. Whisk until the batter is smooth and let the cake cool for 2–3 hours to allow the rich hazelnut flavor to fully develop. That wait makes all the difference.

Q: What’s the best mug size for a microwave cake?

Always use a 12–14 oz microwave-safe mug for the best results. This gives your 2 ingredient Nutella mug cake room to rise without overflowing and ensures even cooking. Avoid narrow or very deep mugs — they can cause uneven texture or undercooked centers.

Q: How do you store leftover mug cake?

Though it’s designed to be enjoyed fresh, you can store a 2 ingredient Nutella mug cake at room temperature for up to 1 day or refrigerate for 2–3 days. To reheat, microwave for 10–15 seconds. Just know that it’s best the day it’s made — especially when shared fresh with someone you love.
