Background

This cake draws inspiration from Italian tiramisu and British trifle traditions, combining the best of both worlds.

Popular across European cafés, this style of layer cake represents the elegance of simple ingredients transformed through proper technique and patience.

Ingredients

• 200g digestive biscuits or ladyfingers
• 300ml strong espresso, cooled
• 500g mascarpone cheese, room temperature
• 200ml heavy cream
• 100g powdered sugar
• 1 tsp vanilla extract
• 3-4 ripe bananas, sliced
• 200g dulce de leche or caramel sauce
• 2 tbsp cocoa powder for dusting
• Optional: 2 tbsp coffee liqueur

Use room temperature mascarpone to prevent lumps in your cream mixture. Choose bananas that are ripe but still firm—they should hold their shape during assembly without becoming mushy.

Step-by-Step Method

1. Prepare a 9-inch springform pan by lining the bottom with parchment paper. Combine cooled espresso with coffee liqueur if using.
2. Make the mascarpone cream by whisking mascarpone until smooth. In a separate bowl, whip heavy cream with powdered sugar and vanilla until soft peaks form. Gently fold whipped cream into mascarpone until just combined—avoid overmixing.
3. Warm dulce de leche slightly in microwave for 20-30 seconds to make it spreadable but not hot.
4. Quickly dip each biscuit in espresso mixture and arrange in a single layer on the pan bottom. Don’t oversoak—a quick dip is sufficient.
5. Spread one-third of mascarpone mixture over biscuits. Layer half the banana slices evenly, then drizzle with one-third of the caramel sauce.
6. Repeat layering process: dipped biscuits, half remaining mascarpone mixture, remaining bananas, and another third of caramel.
7. Create final layer with remaining dipped biscuits, then spread final mascarpone mixture smoothly on top.
8. Warm remaining caramel and create decorative swirls on surface using a knife tip. Cover tightly with plastic wrap.
9. Refrigerate for minimum 4 hours or overnight. Before serving, dust lightly with cocoa powder and carefully remove springform ring.

Pro Tips & Common Mistakes to Avoid

• Don’t oversoak biscuits—they’ll become too soggy and fall apart
• Ensure mascarpone is at room temperature to prevent lumpy cream
• Use firm, ripe bananas to maintain structure and prevent mushiness
• Allow proper chilling time—rushing results in layers that won’t hold

Variations & Substitutions

Replace bananas with fresh strawberries or mixed berries for a fruity twist. Substitute mascarpone with cream cheese mixed with heavy cream for a tangier flavor. For chocolate lovers, add a thin layer of melted chocolate between layers or use chocolate digestive biscuits instead of plain ones.

What to Serve With It

This rich cake pairs beautifully with strong espresso or cappuccino to balance the sweetness. Consider serving alongside fresh berries or a light fruit salad to cleanse the palate between bites.

Storage & Reheating Instructions

Store covered in refrigerator for up to 3 days—the cake actually improves after the first day as flavors meld. This dessert is best served chilled and doesn’t require reheating. Cover tightly to prevent absorption of refrigerator odors.

This stunning Banana Caramel Biscuit Layer Cake proves that the most impressive desserts often require the simplest techniques. With patience and quality ingredients, you’ll create a memorable finale to any meal that guests will request again and again.
