What Is a Lotus Biscoff Mug Cake?
The Origins of the Biscoff Craze
The love for Biscoff started with a crunchy little cookie served alongside coffee.

From there, came the spread — a creamy, dreamy cookie butter that’s now used in cheesecakes, ice cream, and, yes, mug cakes.
The Lotus Biscoff mug cake captures all of that goodness in a warm, fluffy dessert that you can whip up with a spoon in one cozy cup. No preheating, no stress, and absolutely no leftovers to clean up.

Step-by-Step Instructions (Microwave Method)
Preparing Your Mug and Batter
Whipping up a Lotus Biscoff mug cake is nearly as simple as brewing a cup of tea — only it’s sweeter and far more indulgent.
Here’s how to bring your cozy creation to life:
- Choose your mug wisely. Go for a standard 12–14 oz microwave-safe ceramic mug. This allows the batter to expand as it cooks without spilling over the edges.
- Add all dry ingredients first. Mix the flour, baking powder, cinnamon, and brown sugar directly in the mug with a fork.
- Add the wet ingredients. Pour in the milk, oil, and Biscoff spread. Stir well until you get a smooth batter. It should look thick but pourable — like pancake mix.
- Drop in extras (optional). Mix in chocolate chips, sprinkle cookie crumbs, or place a hidden spoonful of Biscoff right in the middle.
- Wipe the rim of the mug so the cake doesn’t stick or bubble over during cooking.
Don’t overmix — just stir until smooth. Overmixing can make your mug cake tough instead of fluffy.
Microwave Timing for a Gooey, Not Dry Texture
This part matters. Every microwave is different, but here’s a solid guideline:
- Microwave on high (usually 1000W–1100W) for 60 to 70 seconds
- If your microwave is lower wattage (700W–900W), cook for 80 to 90 seconds
- The top of the cake should look set and spongy. If it’s still wet, microwave in 10-second bursts
Pro tip: Stop cooking when the edges look set but the center still jiggles slightly. Let it sit for 1 minute — it’ll finish cooking in its own heat, keeping it soft inside.
Want it gooey like lava cake? Under-cook it slightly. Like it firmer? Add 10 seconds. The beauty of a Lotus Biscoff mug cake is how adjustable it is — and how fast you can try again if needed.

How to Make It Egg-Free or Vegan
Easy Egg Substitutes for Mug Cakes
Good news: the classic Lotus Biscoff mug cake doesn’t require eggs to be delicious. In fact, skipping the egg keeps it lighter and softer — and much easier to prep.
But if you’re trying to follow a specific texture, here are a few egg-free options you can try:
| Substitute | Amount | Result |
|---|---|---|
| Applesauce | 1 tbsp | Soft, lightly sweet, moist |
| Mashed banana | 1 tbsp | Dense, slightly fruity |
| Vegan yogurt | 1 tbsp | Rich and creamy |
| Milk only (no egg) | 3 tbsp | Light and fluffy with mild flavor |
For this recipe, no substitute is absolutely required — just skip the egg, and it’ll still turn out soft and cake-like, especially if you use enough oil and milk.
Vegan Biscoff Options & Milk Swaps
Most Lotus Biscoff spreads are naturally vegan — they contain no dairy or eggs. Just make sure to check the label if you’re using an off-brand or flavored version.
To keep your Biscoff mug cake 100% plant-based, here’s what to swap:
- Milk → use almond, oat, soy, or coconut milk
- Butter or cream (if using extra) → skip or replace with vegan margarine
- Chocolate chips (if added) → use dairy-free or dark chocolate chips
With these easy swaps, you can enjoy a vegan Lotus Biscoff mug cake that’s every bit as cozy, gooey, and irresistible as the original.
Best Mug Types and Microwave Tips
Choosing the Right Mug (Size, Material)
Picking the right mug is more important than most people think. To get the best rise, texture, and even cooking for your Lotus Biscoff mug cake, here’s what to use:
- Size: Choose a 12 to 14 oz mug — anything smaller can overflow
- Shape: A straight-sided mug helps the cake rise evenly
- Material: Use ceramic or stoneware, never metal
- No glaze or metallic paint inside — it can spark in the microwave
If you’re using a novelty mug or one with a printed handle, double-check that it says microwave-safe underneath.
Microwave Wattage & Cooking Time Tips
Microwaves vary — and they matter. Here’s how to make sure your Lotus Biscoff mug cake doesn’t turn out undercooked or dry:
| Microwave Power | Time (Approx.) |
|---|---|
| 1000W–1100W | 60–70 seconds |
| 700W–900W | 80–90 seconds |
| Unknown? | Start at 60 secs, check, then add 10 secs if needed |
Let the mug cake rest for 1 minute after cooking. This helps finish the cooking and keeps the center moist.

Final Thoughts on Your Lotus Biscoff Mug Cake
Can I make a Lotus Biscoff mug cake without eggs?
Yes! This recipe doesn’t need eggs to work. In fact, it’s even softer and fluffier without them. Just skip the egg or use 1 tbsp applesauce or mashed banana.
How do you melt Biscoff spread for mug cake recipes?
If the spread is too stiff, warm it in the microwave for 10 to 15 seconds before stirring it in. This helps it incorporate more smoothly into the batter and creates a silkier texture.
Is Biscoff mug cake suitable for vegans?
Absolutely. Just use plant-based milk like oat or almond, and make sure your chocolate chips (if added) are dairy-free. Most Biscoff spreads are naturally vegan.
What kind of mug is best for microwave mug cakes?
Use a 12–14 oz ceramic mug that’s microwave-safe. Avoid metal or small cups — they can cause overflows or uneven cooking.
What causes my Lotus Biscoff mug cake to turn out rubbery or dry?
Overmixing or overcooking is often the cause. Stir gently, and microwave for just 60–70 seconds. Let it rest before eating to lock in moisture.
Can I add chocolate chips or cookies to a Biscoff mug cake?
Yes, and you should! Chocolate chips melt beautifully, and crushed cookies on top add crunch.
The Lotus Biscoff mug cake is proof that you don’t need a fancy kitchen or hours of prep to enjoy a warm, satisfying dessert. With just a spoon, a mug, and five simple ingredients, you can create something that feels indulgent but stays totally effortless.
