The Science Behind Mug Cakes: Why They Work So Well

Mug cakes are not just magic—they work because of basic food science! Here’s why:

✔️ Eggs act as a binder – Holding the structure together while adding moisture.
✔️ Nutella (or any spread) provides fat and sugar – These elements contribute to softness and flavor.
✔️ Microwave heat excites water molecules – The rapid movement of water in the batter creates steam, which makes the cake rise!

The Best Mug for a Mug Cake: Does Size Matter?

Not all mugs are created equal! Using the wrong mug size can make your cake overflow or cook unevenly.

✔️ Best Mug Size: 10-12 oz. microwave-safe ceramic mug.
✔️ Avoid small mugs: The batter will spill over!
✔️ Glass or plastic mugs: They may not distribute heat as evenly as ceramic.

Although mug cakes are best eaten fresh, you can store them for later.

✔️ Refrigerate leftovers: Cover and store for up to 1 day.

✔️ Avoid overcooking: Too much reheating = rubbery texture!
