What Is Banana Biscoff Cake?

Banana Biscoff cake is a modern variation of classic banana cake, enriched with Lotus Biscoff spread — a caramelised biscuit butter made from spiced Belgian biscuits that adds warmth, depth, and richness. The result is a cake that is moist, soft, and rich without being heavy.
Unlike traditional banana bread, which is often dense and minimally decorated, banana Biscoff cake is lighter in texture and more versatile in presentation. It can be baked in loaf tins, square trays, or round layer tins, then finished with buttercream, cream cheese icing, or a simple Biscoff drizzle.
Why Banana and Biscoff Are Such a Good Match

The success of banana Biscoff cake lies in its natural flavour harmony, where gentle sweetness meets warm spice without either element overpowering the other. Bananas are naturally sweet, mellow, and slightly fruity, especially when overripe. Biscoff spread, on the other hand, delivers caramel notes, gentle spice, and biscuit warmth.
Together, they create a balanced flavour profile where:
- Banana provides moisture and softness
- Biscoff adds richness and complexity
- Cinnamon and ginger (when used) act as bridge spices
Neither ingredient dominates, which is why the cake appeals even to people who don’t usually enjoy banana desserts.
The Role of Ripe Bananas in Texture and Structure

Ripe bananas are essential to the success of banana Biscoff cake, both for flavour and structural balance. Ideally, they should be heavily speckled or mostly brown. At this stage, bananas perform three critical functions:
First, they provide sweetness, reducing the need for excessive added sugar. Second, they contribute moisture, keeping the cake soft for days. Third, they help bind the batter, acting similarly to eggs in structure.
Using underripe bananas leads to bland flavour and drier texture, while ripe bananas enhance both taste and crumb quality.
Butter-Based vs Oil-Based Banana Biscoff Cakes

One of the most noticeable differences between banana Biscoff cake recipes lies in the choice of fat, which directly affects flavour, texture, and shelf life.
Butter-based cakes deliver richness and classic flavour. They are ideal for celebration cakes and buttercream pairings. Oil-based cakes, on the other hand, stay moist for longer, slice cleanly even when cold, and are excellent for make-ahead baking or warm climates.
Both work well with Biscoff. The key is understanding that oil emphasises moisture, while butter emphasises flavour.
Sugar Choices and Why They Matter

Using the right sugar combination plays a crucial role in shaping the flavour, colour, and moisture of banana Biscoff cake. Brown sugar, particularly soft brown or demerara, adds caramel depth that complements Biscoff perfectly. Caster or white sugar lightens the crumb and balances sweetness.
Many successful recipes use a dual-sugar approach, combining brown sugar for flavour and moisture with lighter sugar for structure. This prevents the cake from becoming too heavy or overly sweet.
Spices That Elevate Banana Biscoff Cake

While cinnamon is the most commonly used spice, a small amount of ground ginger adds depth and a bakery-style warmth that enhances the caramel notes of Biscoff. Ginger echoes the spice notes already present in Biscoff biscuits and enhances warmth without overpowering the banana.
Used lightly, spices act as background notes rather than dominant flavours, making the cake taste deeper and more refined.
How Biscoff Is Best Used in the Cake

One of the most important techniques in banana Biscoff cake is controlling how and where the Biscoff is used within the recipe.
Mixing small amounts into the banana mash ensures even flavour distribution. Dolloping and swirling Biscoff on top of the batter creates visual appeal without weighing down the sponge. Reserving larger quantities for frosting or filling keeps the cake balanced rather than greasy.
This separation of roles allows banana flavour to shine in the sponge while Biscoff adds indulgence through toppings and layers.
Buttercream vs Cream Cheese Icing

Banana Biscoff cake pairs beautifully with two main icing styles.
Biscoff buttercream is rich, smooth, and indulgent. It highlights the caramelised biscuit flavour and works well for piped decorations and drip cakes.
Biscoff cream cheese icing introduces a gentle tang that balances sweetness. It feels lighter on the palate and suits cakes intended as desserts rather than formal celebration bakes.
Both are excellent choices, and the decision comes down to personal preference and occasion.
How to Achieve a Perfect Layer Cake

For layered banana Biscoff cakes, technique matters just as much as ingredients, especially when aiming for clean layers and a stable finish.
Using slightly lower oven temperatures helps cakes bake flat, making stacking easier. A crumb coat seals loose crumbs and creates a smooth surface. Chilling between frosting layers is essential, especially if adding a caramel or Biscoff drip.
Adding crushed Biscoff biscuits between layers introduces texture without compromising moisture, creating contrast between soft sponge and gentle crunch.
Caramel and Biscoff Drips: What Actually Works

Creating a clean Biscoff or caramel drip requires patience, precise temperature control, and a properly chilled cake base. The cake must be chilled, the frosting set, and the drip warm but not hot.
Applying small amounts and allowing gravity to guide the drip prevents mess and uneven streaks. Biscoff and caramel drips should always be tested before application to avoid sinking or sliding.
Baking Temperature and Timing Explained

Oil-based banana Biscoff cakes benefit from longer, slightly cooler bakes, while butter-based versions prefer moderate heat. Rushing the bake risks a greasy centre or collapsed crumb.
Testing doneness with a skewer and allowing the cake to cool gradually ensures structure sets properly.
Storage, Shelf Life, and Freezing

Banana Biscoff cake stores exceptionally well, making it an excellent option for advance baking and special occasions. At room temperature, it stays fresh for up to three days when sealed. Refrigeration is best used only to set frosting rather than for long-term storage.
The cake freezes well, even fully decorated. Freezing uncovered until firm before wrapping protects decoration and prevents condensation damage when thawing.
Common Myths About Banana Biscoff Cake
One common myth is that adding more Biscoff always improves flavour. In reality, too much Biscoff can overwhelm banana and create an oily texture.
Another misconception is that drip cakes should be decorated warm. Proper chilling is essential for clean results.
Understanding these myths helps bakers achieve consistent success.

3. Can I make banana Biscoff cake without eggs?
Yes, banana Biscoff cake can be made eggless. Mashed bananas already help with binding, and eggs can be replaced with yoghurt, buttermilk, or a flaxseed mixture. The texture may be slightly denser but still moist and flavourful.
4. Can I make banana Biscoff cake without an oven?
Yes, banana Biscoff cake can be made without an oven using a heavy-bottomed pan or pressure cooker on low heat. The cake should be cooked slowly with a lid on, and baking time may vary depending on the method used.
5. What icing goes best with banana Biscoff cake?
Both Biscoff buttercream and Biscoff cream cheese icing work well. Buttercream gives a rich, indulgent finish, while cream cheese icing adds a light tang that balances the sweetness of the cake.
6. Can I reduce the sugar in banana Biscoff cake?
Yes, sugar can be reduced slightly because ripe bananas and Biscoff spread already add sweetness. However, reducing sugar too much may affect the cake’s texture and moisture.
7. Why is my banana Biscoff cake dense or heavy?
A dense cake can result from overmixing the batter, using underripe bananas, or incorrect oven temperature. Mixing until just combined and using ripe bananas helps achieve a lighter texture.
8. Can I use plain flour instead of self-raising flour?
Yes, plain or all-purpose flour can be used, but you must add baking powder. A general rule is to add about 2 teaspoons of baking powder per 200g of plain flour to achieve proper rise.
9. How do I stop Biscoff from sinking in the cake?
To prevent Biscoff from sinking, gently swirl small spoonfuls on top of the batter rather than mixing large amounts directly into it. This keeps the cake balanced and avoids oily patches.
10. How long does banana Biscoff cake last?
Banana Biscoff cake stays fresh for up to 3 days when stored in an airtight container at room temperature. If refrigerated, it can last up to 5 days but should be brought to room temperature before serving.
11. Can banana Biscoff cake be frozen?
Yes, banana Biscoff cake freezes well. You can freeze the sponge alone or fully decorated. Wrap it tightly once frozen solid and thaw at room temperature for best results.
12. Is Lotus Biscoff spread vegan?
Yes, Lotus Biscoff spread is naturally vegan, as it is made from plant-based ingredients. However, the overall cake may not be vegan unless eggs, butter, and dairy are replaced.
13. Can I make banana Biscoff cake as a loaf instead of a layer cake?
Yes, the same batter can be baked as a loaf cake. Baking time will be longer, usually 45–60 minutes, depending on oven temperature and tin size.
14. Why did my banana Biscoff cake sink in the middle?
This usually happens if the cake is underbaked, the oven door is opened too early, or too much moisture is added. Always check doneness with a skewer before removing the cake from the oven.
15. Can I add chocolate or nuts to banana Biscoff cake?
Yes, chopped walnuts, pecans, or dark chocolate chips pair well with banana and Biscoff flavours. Add them gently at the end of mixing to avoid overworking the batter.
