Cooking Guide

What type of mug is best for cooking?

Use a microwave-safe mug with at least 10 oz (300 ml) capacity to ensure even cooking and room for the cake to rise.

Can I substitute plant-based milk?

Yes, dairy or plant-based milks like almond or soy work well, maintaining moisture and texture.

How do I make a chocolate version?

Add 1 tbsp unsweetened cocoa powder to the dry ingredients for a rich chocolatey taste.

What if the cake is dry or overcooked?

Reduce microwave time slightly or use oil to keep the texture moist. Cooking times vary by microwave wattage.

Can I add mix-ins for extra flavor?

Absolutely, chocolate chips, berries, or nut butters can be folded in before microwaving for added taste and texture.
