- Made in 5 minutes
- Single serving so no wastage
- Customise the flavours
- Minimal washing up
- Beautifully moist sponge
🥘 Ingredients
- Biscoff Spread - the spread version of the famous caramelised spicy Biscoff biscuits. I used the smooth spread in this recipe.
- Flour - white plain flour.
- Sugar - white caster sugar or golden caster sugar could also be used.
- Baking Powder - you'll need a ¼ teaspoon.
- Egg - 1 medium free-range egg.
- Milk - whole milk is best but semi-skimmed can also be used.
- Vegetable Oil - or substitute with melted butter.
🔪 Instructions
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: Place the biscoff spread in a large mug and soften for 10 seconds in the microwave.
Two: Place the other ingredients into the mug.
Three: Use a small whisk or fork to mix the batter together. Make sure you scrape the biscoff spread off the bottom of the mug so that it incorporates into the whole cake batter. Wipe the sides of the mug clean with a paper towel.
Four: Microwave for 60 seconds then continue to microwave for 30 seconds at a time. I have a 900 watt microwave and my mug cake was ready in 2 minutes. For an extra biscoff hit, spoon 1 tablespoon of biscoff spread on top of the mug cake and let it melt into the hot sponge.
💭 Top tips
- Try not to over mix the mug cake as it can toughen the cake.
- Don’t over-microwave! Check after 60 seconds and then every 30 seconds after that.
- Make sure your mug has no metal or metallic paint on it. You wouldn't want your microwave exploding on you.
- If you don’t have a microwave you can bake the mug cake at (180°C) for 8 minutes.
- Use a piece of paper towel to wipe down the sides of the mug before microwaving to ensure a smooth rise.
🍴 Serving suggestions
I like to sprinkle some Biscoff cookie crumbs on top of the mug cake for added crunch and texture. It also goes really well with honeycomb ice cream and chocolate sauce.
📖 Variations
- Use Nutella or chocolate spread instead of Biscoff spread.
- Add in a small handful of chocolate chips to the mixture.
- Use light brown sugar for a deeper caramelised flavour.
🥡 Storage
Mug cakes are best eaten fresh out of the microwave. If you have any leftovers they can be reheated up to 24 hours later. Mug cakes aren't suitable for freezing.
You can make the batter ahead of time and store it in the mug, covered with clingfilm, until you are ready to cook it.
❓ FAQS
Yes, biscoff spread is suitable for vegans.
Over mixing the batter can cause mug cakes to become tough.
You used a mug that was too small for the quantity of mixture. An over-sized coffee mug is best for mug cakes.

It wasn't bad at all! I would recommend using a big mug though, it spilt over the edge in the microwave on mine!
