What is the flavour of Biscoff?

Biscoff has a deep caramel flavour combined with warm spices. This sweet, spiced flavour is known as speculoos which is what Lotus Biscoff biscuits taste like.

Biscoff biscuits taste a bit like gingerbread but have a deeper caramel flavour and a crisp biscuit texture. The spiced speculoos flavour of Biscoff biscuits is a mix of warm, sweet spices - cinnamon, nutmeg, ginger, allspice, and cloves.

Ingredients You'll Need:

  • Biscoff Spread. The key ingredient! You can use any version that you like - I used the Lotus Biscoff Smooth Spread.
  • Whole milk. This can be swapped out for a lactose-free version if preferred.
  • Oil. Any light oil will work for this recipe such as vegetable oil, canola oil, or coconut oil.
  • Egg. Room temperature eggs are best.
  • Vanilla extract. Adds some extra delicious flavour to this recipe.
  • Baking powder. This is what gives the mug cake the perfect light texture.
  • Light brown sugar. Adds the perfect touch of caramelised sweetness to the cake.
  • All-purpose flour. Be sure to measure your flour accurately for best results.

Optional mug cake toppings

  • Crushed Biscoff biscuits
  • Lotus Biscoff Spread
  • White chocolate chips
  • A dollop of whipped cream
  • Chopped pecan nuts
  • A scoop of ice-cream

How to make Biscoff cake in a mug

STEP ONE

In a large, microwave-safe mug, whisk together the Biscoff Spread, milk, oil, egg, and vanilla extract.

STEP TWO

Once well combined, add the remaining ingredients and mix together gently.

STEP THREE

Microwave for 3 - 5 minutes or until the cake is just cooked through.

STEP FOUR

Add any toppings you would like and enjoy warm. I used crushed Biscoff Biscuits and a dollop of Biscoff Spread.

RECIPE TIPS & TRICKS

  • Depending on the power of your microwave, you may need to adjust the cooking time of the mug cake. Start by cooking it for less time, and then cook more if required.
  • Make sure to measure the ingredients accurately. To measure the flour correctly make sure it is completely level with the top of your measuring cup.
  • This recipe was made for the microwave, but if you don’t have a microwave you can bake the mug cake at 375F / 180°C for 8 - 10 minutes.
  • Be careful to not overmix the mug cake batter. When you are adding the dry ingredients (step 2), mix until the batter is just combined.

Mug Cake FAQS

How do I know when my mug cake is cooked?

Use the time provided in the recipe as a guide, but remember that each microwave is different so it is going to take a little bit of practice to find your perfect amount of time.

Once your mug cake has finished cooking it should be slightly wet and sticky in the centre. If it's too wet, put it back in the microwave for 5 - 10 second increments until you achieve the perfect, slightly sticky consistency that will give you a fluffy mug cake.

How do I store my mug cake?

Mug cakes are best eaten warm & freshly made. But if you do have any leftovers they can be reheated and enjoyed within the day of making. Mug cakes aren't suitable for freezing but the batter can be made in advance. Simply make the batter ahead of time and store it in the mug. Cover the mug with cling wrap until you are ready to cook it.

Why did my mug cake mixture overflow?

If your mug cake recipe overflowed whilst cooking in the microwave, it is most likely because there was too much batter in the mug. I always fill my mug ¾ full of the cake batter to avoid overflowing. So be sure to use a big enough mug to avoid your cake from spilling over the sides of your mug while cooking.
