This 3-Ingredient Vegan Biscoff Mug Cake is moist, fluffy and perfectly rich. It's quick and easy to make and can be made in the microwave or the oven. Perfect for when you're craving something sweet but can't be bothered to make a whole dessert!

What is Biscoff spread?


Biscoff spread is also known as Speculoos, cookie butter or cookie spread. It's made with blended up Lotus biscuits (also known as Speculoos biscuits). You can buy either smooth or crunchy Biscoff spread, and for this recipe I recommend the smooth one.

What does Biscoff spread taste like?


It's rich, has a sweet, caramel-like flavour and is warm and fragrant from the spices. Its flavour is very versatile and works well in a wide range of desserts.

Is Biscoff spread vegan?


Yes, Biscoff spread is accidentally vegan.

Is Biscoff spread gluten-free?


No, unfortunately it's not gluten-free. This is because it's made with blended up Lotus biscuits, which contain gluten.

Where can you buy Biscoff spread?


You can find Biscoff spread in the condiments section of most supermarkets, next to the jam and peanut butter etc.

Can you make mug cake in a bowl?


Yes - if you don't have a mug, you can make it in a small bowl instead.

Can you make mug cake in the oven instead of the microwave?


Yes - bake at 180 degrees Celsius (350 degrees Fahrenheit) for around 15 minutes, or until risen and an inserted skewer or fork comes out clean.

How to make this recipe

  • Mix all ingredients together in a mug or small bowl.

  • Microwave for 50 seconds, or until the cake has risen and cooked through – test with a skewer or fork and make sure it comes out clean.

Tip: If still not cooked, microwave again in 10-second bursts until an inserted skewer or fork comes out clean.

Ingredients you can add to the batter

  • Chocolate chips.
  • Pieces of chopped apple or grated apple. Although bear in mind that you will have to adjust the cooking time accordingly. Just microwave the cake in extra 10-second bursts until the cake has risen and cooked through - test with a skewer or fork and make sure it comes out clean.
  • Fresh or frozen raspberries.
  • An extra teaspoon of Biscoff spread in the middle of the batter cake. This creates a lava cake effect as the Biscoff spread melts and gets super gooey in the microwave.

Can you make this gluten-free?

Unfortunately not, as Biscoff spread contains gluten! If you're looking for something gluten-free, I'd recommend my Vegan Peanut Butter Mug Cake, which is a very similar recipe. It's also refined sugar free!

Serving suggestions

  • Vegan vanilla ice cream.
  • Vegan chocolate ice cream.
  • Peanut butter or almond butter.
  • Coconut whipped cream.

    What does the apple add? Like does it change the consistency/taste

      It doesn't change the consistency of the cake batter, but it does add a different texture overall (because you get the texture of the apple too) and adds extra flavour too!

    Looks great! Was wondering if you could replace the plain flour and baking powder with self-raising flour?
