Ingredients You’ll Need
Before you start, gather all ingredients. This makes the process smooth and stress-free.
Core Ingredients
- Biscoff spread (cookie butter) – This gives the cake its signature flavor and moisture
- All-purpose flour – Forms the structure of the cake
- Sugar – Adds sweetness and balances the spice notes
- Baking powder – Helps the cake rise in the microwave
- Milk – Keeps the batter smooth and soft (any milk works)
- Neutral oil – Adds moisture and prevents dryness
- Vanilla extract (optional) – Enhances overall flavor
Optional Add-Ins
- Extra Biscoff spread for a molten center
- Crushed Lotus Biscoff cookies for texture
- Chocolate chips for added richness
- A pinch of salt to balance sweetness
Each of these extras is optional, but they can elevate the final result if you enjoy richer desserts.
Choosing the Right Mug
The mug matters more than most people think.
Use a microwave-safe mug that holds at least 12 to 14 ounces. This gives the cake enough room to rise without overflowing. Ceramic mugs work best. Avoid very narrow or thin mugs, as they can cook unevenly.
Lightly greasing the mug with oil or butter helps prevent sticking, especially if you plan to eat the cake outside the mug.
Biscoff Mug Cake Recipe (Step-by-Step Method)
This is the core section of the recipe. Follow each step carefully for the best results.
Step 1: Prepare Mug & Add Biscoff Spread
Place your microwave-safe mug on a flat surface. Lightly grease the inside using a small amount of oil or butter. This step helps the cake release easily and keeps the sides soft.
Spoon the Biscoff spread into the mug. If the spread feels very thick, microwave it for 10–15 seconds to soften it slightly. This makes mixing easier and helps it blend smoothly into the batter.
Step 2: Add the Dry Ingredients
Add the flour, sugar, and baking powder directly into the mug. Use a fork to gently mix them with the Biscoff spread. Take your time here. Break up any lumps so the mixture looks thick but even.
Step 3: Pour in the Wet Ingredients
Add the milk, oil, and vanilla extract. Stir slowly and thoroughly until the batter becomes smooth. Make sure to scrape the bottom and sides of the mug so no dry flour remains.
The batter should be thick but pourable. If it feels too dry, add one extra tablespoon of milk.
Step 4: Create a Biscoff Center (Optional)
If you want a gooey middle, add a small spoon of Biscoff spread to the center of the batter. Gently push it down without stirring. This will melt while cooking and create a soft, rich core.
Step 5: Microwave the Cake
Place the mug in the microwave. Cook on high power for 60 seconds first. Check the cake. The edges should look set while the center is slightly soft.
If needed, microwave in 10–15 second intervals until done. Most microwaves finish the cake between 70 and 90 seconds. Avoid overcooking. A slightly soft center will firm up as the cake rests.
Step 6: Rest and Finish
Remove the mug carefully, as it will be hot. Let the cake rest for 1–2 minutes. This allows the texture to settle and prevents dryness.
Top with extra Biscoff spread, crushed cookies, or a scoop of ice cream if desired.
Microwave Tips for Perfect Results
Microwaves vary in power, so small adjustments may be needed.
Keep these tips in mind:
- Always start with less cooking time
- Use a wider mug for even cooking
- Do not fill the mug more than halfway
- Stop cooking when the top looks just set
If the cake feels dry, it was likely overcooked. Next time, reduce the cooking time slightly.

Serving Suggestions
This cake is best served warm.

For a more indulgent dessert, drizzle warm Biscoff spread over the top just before serving.
Common Questions About Biscoff Mug Cake
Why did my mug cake turn out dry?
Dry cakes usually mean overcooking. Reduce microwave time and allow resting before eating.
Can I bake this instead of microwaving?
Yes. Bake in an oven-safe ramekin at 180°C (350°F) for about 12–15 minutes.
Can I store a mug cake?
Mug cakes are best eaten fresh. If needed, cover and store for a few hours at room temperature. Reheat briefly before eating.
What can I use instead of Biscoff spread?
You can try peanut butter or chocolate spread, but the flavor will be different. Biscoff gives the signature caramel taste.
