Tips & notes
- Do not overcook: Slightly undercooking the mug cake keeps the center soft, fluffy, and gooey instead of dry.
- Microwave times can vary: Every microwave is different, so start with less time and add extra time if needed.
- Add a splash of extra milk if needed: If your batter feels too thick, a little extra milk will help loosen it and keep the texture soft.
- Protein powders absorb differently: Some protein powders soak up more liquid than others, so you may need to slightly adjust the milk depending on the brand you use.
- Use a larger mug or ramekin: The mug cake rises while cooking, so using a slightly bigger mug helps prevent it from overflowing.
- Best enjoyed warm: This mug cake tastes best straight after cooking while the chocolate chips are still melted and gooey.
- Add extra toppings: Try topping with yoghurt, nut butter, berries, or extra melted chocolate for something even more delicious.
- Chocolate protein powder works too: If you prefer a richer chocolate flavor, chocolate protein powder is a great option.
- Make it extra gooey: Adding a few extra chocolate chips in the center before microwaving creates an even softer middle.
