FAQs

Can I make this in the oven instead of the microwave?

Yes! Bake at 350°F (175°C) in an oven-safe ramekin for 12-15 minutes.

What’s the best flour to use?

White, spelt, oat, or almond flour all work well. Almond flour makes it denser, while white and oat flour keep it fluffy.

How do I make this cake extra moist?

Use applesauce or an egg instead of water for a richer texture.

Can I make this without sweetener?

Yes! You can replace sugar with mashed banana or unsweetened applesauce for natural sweetness.

How do I prevent my mug cake from being dry?

Avoid overcooking! Start with 50 seconds and check for doneness. Adding a bit more oil or applesauce can also help.

Can I double the recipe?

It’s best to make individual servings, but you can split a double batch between two mugs and microwave separately.

What’s the best way to serve this?

Enjoy as-is, or top with powdered sugar, whipped cream, or a drizzle of caramel.

Can I use whole wheat flour?

Yes, but the cake may be a bit denser. You can mix whole wheat flour with white flour for better texture.

How do I make it dairy-free?

Use applesauce or oil instead of butter and ensure your sweetener is dairy-free.

Can I add mix-ins?

Absolutely! Try mini chocolate chips, raisins, or coconut flakes for added flavor.
