BISCOFF MUGCAKE RECIPE

Step 1. Melt Biscoff

Add a generous amount of Biscoff Cookie Butter to your microwave-safe cup. Just enough to soften the cookie butter, microwave it for 10 second. It will make it easier to combine and the warm caramelized flavor will spread evenly through your cake.

Step 2: Mixing the Wet Ingredients 

After the Biscoff has melted, add milk, oil and vanilla extract. Stir all ingredients together until mixture is smooth and creamy. Check that there are no cookie butter lumps at the bottom.

Step 3: Add Dry Ingredients 

Sprinkle in the flour, sugar and baking powder. Also add a pinch of salt. Mix everything gently until it is all combined. Avoid overmixing as this can result in a dense cake instead of a fluffy one. The batter should be slightly thick and smooth.

Step 4: Microwave it

Start by placing your mug into the microwave on for 50 seconds. If the center still appears wet, microwave in 10- to 20-second bursts for a few more seconds until it is set but soft on the inside. Every microwave is unique, so make sure to adjust your settings accordingly.

Step 5: Let it rest and enjoy

After you’ve finished, let the mug cake rest for 30 second before enjoying. This resting period allows the texture of the cake to become fluffy and settle. Top it with a drizzle or scoop of vanilla ice-cream, or melt Biscoff.

Tip For a gooey center that melts in the microwave, remove it a few moments early. It will finish cooking while it is resting.

Topping Ideas

• Vanilla ice cream
• Biscoff cookies & whipped cream
• Caramel drizzle
• Sea salt flakes
• Fresh berries
• Chocolate chips

Fun Variations

• Nutella mug cake: Replace cookie butter with Nutella
• Peanut Butter version: Replace Biscoff creamy peanut butter.
• Banana Biscoff: Add mashed ripe bananas for additional moisture and flavor.
• Vegan Alternative: Use oil and almond milk instead of dairy.

Pair it with

• Espresso or hot coffee
• Spiced latte or Chai tea
• Cold milk

Storing Tips

The cake is best served fresh. However, you can cover it and chill it up to 24 hours. You can reheat the cake in the microwave by 20 seconds. Do not freeze, as it will lose its soft texture.

FAQs

1. Can I make it without a microwavable?

Yes, you can! Pour the batter in a ramekin that can be used in an oven and bake it at 350degF (175degC), until the top has set. The result will be just as tasty, even though it won’t take as long.

2. Can I use regular butter in place of oil?

Absolutely. The cake will taste richer with melted butter. Make sure the butter is slightly cooled down before adding it.

3. What type of milk should I buy?

You can use any kind of milk: whole milk, almond milk, oat milk, and soymilk all work well. The cake will remain soft and moist.

4. When should I bake my mug cakes?

If it’s still wet in the center, microwave it at intervals of 10 seconds until you get the right texture. Microwave it at 10 second intervals if it is still wet.

5. What toppings and mix-ins can I add?

Definitely! Add chocolate chip, crushed Biscoff cookie or a teaspoon of nutella to the center and microwave for a gooey surprise.
