Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

all-purpose flour
baking powder
brown sugar
milk
Biscoff cookie butter spread
vegetable oil or melted butter
vanilla extract
pinch of salt

Optional toppings:

crushed Biscoff cookies
whipped cream
extra drizzle of Biscoff spread

Directions

I grab a microwave-safe mug and add the flour, baking powder, brown sugar, and salt. I mix them together with a fork.
I stir in the milk, Biscoff spread, oil or melted butter, and vanilla until the batter is smooth and well combined.
I microwave the mug on high for 50 to 60 seconds, depending on my microwave’s power. I check the center to make sure it’s set.
I let it cool for a minute or two, then top it with crushed cookies, whipped cream, or an extra spoonful of Biscoff if I’m feeling extra indulgent.

Servings and timing

This recipe makes 1 mug cake (single serving).
Prep time: 2–3 minutes
Cook time: 1 minute
Cooling time: 1–2 minutes

Variations

Sometimes I mix in white chocolate chips or a small handful of crushed Biscoff cookies for added texture. For a molten center, I drop a teaspoon of Biscoff spread into the middle before microwaving. I’ve also tried a splash of espresso or cinnamon in the batter to change things up. It’s easy to experiment and make it my own every time.

storage/reheating

This mug cake is best enjoyed fresh and warm, straight from the microwave. If I don’t finish it right away, I cover the mug and refrigerate it for up to 1 day, then microwave it for about 10–15 seconds to warm it back up. The texture is always best the same day, though.

FAQs

Can I make this without baking powder?

I don’t recommend skipping it—it helps the cake rise and gives it that fluffy texture. Without it, the cake turns out dense.

What kind of mug should I use?

I use a standard microwave-safe mug that holds at least 10–12 ounces to prevent overflow as it cooks.

Can I make it dairy-free?

Yes, I use a plant-based milk and swap the butter for coconut oil or any neutral vegetable oil.

Why did my mug cake come out rubbery?

That usually means it was overcooked. I microwave in short intervals and check at 50 seconds to avoid drying it out.

Can I double the recipe?

Yes, but I divide it between two mugs. Microwaving a larger portion in one mug can lead to uneven cooking.

Conclusion

This 1-minute Biscoff mug cake is the perfect answer to last-minute dessert cravings. It’s fast, flavorful, and incredibly satisfying with its warm cookie butter richness and soft, cake-like texture. I love how easy it is to make with pantry staples and how indulgent it tastes with zero fuss.
