What can I mix into my coffee mug cake for extra flavor?
Absolutely! You can customize your mug cake with delicious add-ins like chopped nuts, chocolate chips, or a spoonful of peanut butter – just stir them in before microwaving for a personalized treat.
How can I tell if my coffee mug cake is fully cooked?
Your mug cake is done when it’s puffed up and the surface looks firm but still moist. Gently press the top – it should spring back lightly. Since microwave strengths differ, watch closely to avoid over-baking for perfect results every time.
How to make a vegan coffee mug cake?
Absolutely! For a vegan version, simply swap dairy milk with plant-based alternatives like almond, soy, or oat milk. Use vegetable oil or melted coconut oil instead of butter. Just remember to verify that your cocoa powder and other ingredients are vegan-certified for a completely plant-based treat.
Can I make coffee mug cake batter ahead of time?
For best results, mix and microwave the batter right away. However, you can prepare the dry ingredients in advance—store them in an airtight container. When you’re ready to bake, simply add the wet ingredients and microwave!
