FAQs : Lotus Biscoff Mug Cake

Can I make this Biscoff mug cake without a microwave?

Yes! While this recipe is designed for the microwave, you can bake it in an oven-safe ramekin at 350°F (175°C) for 12–15 minutes. If you have an air fryer, cook it at 330°F (165°C) for 8–10 minutes. The texture is slightly denser than the microwave version but still delicious.

Can I make this recipe eggless?

Absolutely! This Lotus Biscoff Mug Cake recipe is naturally eggless. The combination of milk, oil, and Biscoff spread keeps it soft and moist. For a vegan version, just use plant-based milk and a dairy-free whipped topping.

What toppings go well with a Biscoff mug cake?

A drizzle of warm Biscoff cookie butter
Crushed Biscoff biscuits for crunch
Vanilla or cinnamon ice cream for contrast
Whipped cream with a sprinkle of cinnamon
Chocolate chips or caramel sauce for extra indulgence

Can I make this cake in an oven or air fryer?

Yes, you can! As mentioned earlier:
Oven: Bake in a ramekin at 350°F for 12–15 minutes
Air Fryer: Cook at 330°F for 8–10 minutes
Both methods work, but the microwave gives the quickest, fluffiest result.

What is a substitute for Biscoff cookie butter?

If you can’t find Biscoff, any speculoos spread works well. Trader Joe’s Cookie Butter is a popular alternative. Nutella can be used, but it changes the flavor profile to chocolate-hazelnut rather than caramel spice.

Why is my Biscoff mug cake dry?

This usually happens if you:
Added too much flour
Cooked it too long in the microwave
Skipped the oil
💡 Fix: Reduce cook time by 10 seconds and check earlier.

Is Biscoff spread vegan?

Yes! Original Lotus Biscoff spread is vegan-friendly, making this an easy plant-based dessert option when paired with dairy-free milk.

Why is my mug cake tough and chewy?

Overmixing the batter develops gluten, which leads to a chewy texture. Mix only until ingredients are combined.

Why did my mug cake mixture overflow?

This happens when the mug is too small. Always use a 10–12 oz microwave-safe mug, and fill it no more than halfway to allow room for rising.
