FAQs
Can I make this Biscoff Mug Cake dairy-free?
Yes! Just swap the milk with almond, oat, or soy milk, and use a plant-based butter alternative. The texture stays rich and satisfying.
How do I know when my mug cake is done?
Microwave ovens vary, but you’ll know it’s ready when the top looks set and springs back slightly to the touch. Start with 60 seconds and add in 10-second bursts if needed.
Can I double the recipe?
Absolutely—but divide it between two mugs. Overfilling one mug can cause it to spill over during cooking.
Is there a gluten-free version?
Yes. Use a 1:1 gluten-free flour blend instead of regular flour. The result is slightly more dense but still delicious.
How long does it stay fresh?
This cake is best enjoyed warm and fresh out of the microwave. It can dry out quickly if left too long.
