Banana Caramel Tartlets A Simple Sweet Treat

The Cream Went In Before the Caramel Was Cold

I piped the whipped cream straight onto warm dulce de leche and watched it start to slide almost immediately.

Not a disaster. Just a mess, and one I could have avoided if I’d waited another fifteen minutes before touching the assembled tartlets.

That was the third batch. The first two had other problems.

What the Base Actually Does

Most recipes tell you to press the biscuit mixture in and move on. They don’t mention that if the butter ratio is slightly off — even by ten grams — the base either crumbles when you unmold it or comes out so solid it’s unpleasant to cut through.

50g of butter to 100g of digestives is the ratio that worked for me. Not less.

The sea salt goes into the base mixture, not just on top at the end. I thought about adding it only as a garnish — actually no, I kept it in both places, and the base tasted noticeably flat the one time I skipped it in the mix.

Bake at 180°C for 10 to 12 minutes. Mine went golden at exactly 11 minutes in a fan oven. Pull them when the edges look set and the color has shifted from pale to something warmer. Then leave them completely alone until they’re cool — not warm, cool.

Quick tip: Press the biscuit mixture up the sides of the mold with the back of a small spoon, not your fingers. Fingers warm the butter and the mixture starts slipping before it’s set.

About the Dulce de Leche

50g per tartlet sounds like a lot until you spread it and realize it’s a thin, even layer — which is exactly what you want.

Spread it cold, straight from the fridge. Room-temperature dulce de leche moves too freely and pools at the edges instead of staying where you put it.

The banana goes on immediately after, while the caramel is still slightly tacky. That tackiness is what keeps the slices from shifting when you add the cream.

Slice the bananas about 5mm thick — thin enough to layer properly, thick enough that they don’t turn to mush under the weight of the cream. My sister thought I was being overly precise about this. She wasn’t wrong, but the difference is visible when you cut into a finished tartlet.

The Cream Situation

Whip the 200ml of heavy cream with 2 tablespoons of powdered sugar and 1 teaspoon of vanilla extract until you hit soft peaks.

Stop there.

Stiff peaks look tidier when you pipe them, but they hold less well under the drizzle and tend to taste slightly grainy compared to a softer whip. I kept going past soft peaks on my second attempt, and the texture was noticeably different — denser, less pleasant against the caramel.

The drizzle of remaining dulce de leche goes on last, in thin lines across the cream. Use a spoon or a piping bag with a very small hole. It needs to be room temperature for this — cold dulce de leche won’t flow evenly, it’ll clump.

Grated dark chocolate over the top. 25g sounds modest but it covers four tartlets with enough to actually taste. Don’t skip the final pinch of sea salt — it lands on the cream and chocolate and does something to the sweetness that I can’t fully explain without sounding dramatic.

The Part That Keeps Going Wrong for Me

Timing.

These tartlets need to be served the moment they’re assembled, or within about 20 minutes of finishing. The biscuit base starts absorbing moisture from the caramel and cream faster than I expected — not within hours, within 30 or 40 minutes at room temperature.

The first time I made them for more than just myself, I assembled everything 45 minutes before people arrived. The bases weren’t soggy exactly, but they’d lost that snap. It’s a real problem if you’re planning ahead.

What I do now: bake and cool the bases ahead, keep the dulce de leche in the fridge, whip the cream and refrigerate it separately, then assemble everything right before serving. The whole assembly takes about 8 minutes once everything is prepped and cold.

Does everyone find this annoying? Possibly. I find it annoying. But the alternative is a soft base, and that’s not the same dessert.

Ingredients

100g digestive biscuits, crushed — 50g butter, melted — 200g dulce de leche or caramel sauce — 2 ripe bananas, sliced — 200ml heavy cream, whipped — 25g dark chocolate, grated — 2 tablespoons powdered sugar — 1 teaspoon vanilla extract — Pinch of sea salt

Fun fact: Bananas continue to ripen after they’re picked because they produce ethylene gas, which also accelerates the ripening of everything stored near them — including other bananas. The riper the banana here, the sweeter and more pronounced the flavor against the caramel.

Instructions

Step 1: Crush 100g of digestive biscuits into fine crumbs — not powder, but no large chunks either. Mix with 50g of melted butter and a pinch of sea salt until the mixture holds together when you press a small amount between your fingers. If it falls apart, the butter wasn’t enough.

Step 2: Divide the mixture equally among 4 tartlet molds, pressing firmly into the base and up the sides. Use the back of a small spoon for the sides (not your fingers — the warmth melts the butter and the mixture slides). Press firmly — under-pressed bases fall apart when unmolded.

Step 3: Bake at 180°C for 10–12 minutes, until the bases turn golden and smell faintly nutty. Mine were done at 11 minutes. Remove from the oven and leave completely alone until fully cool — this took about 25 minutes on my counter. (Rushing this step and adding cold caramel to a warm base causes condensation under the dulce de leche layer, and the base goes soft faster.)

Step 4: Spread 50g of dulce de leche evenly onto each cooled base. Use cold dulce de leche — it stays put. Room temperature caramel slides to the edges before you can stop it. I watched this happen in real time on my second attempt and felt genuinely irritated with myself.

Step 5: Arrange banana slices in an overlapping layer across the caramel while it’s still slightly tacky. Slice bananas to about 5mm — thick enough to hold their shape, thin enough to lie flat. Cover the surface evenly; gaps in the banana layer mean gaps in every bite.

Step 6: Whip 200ml of heavy cream with 2 tablespoons of powdered sugar and 1 teaspoon of vanilla extract until soft peaks form. Stop before stiff peaks — the texture at soft peaks is better against the caramel. Pipe or spoon generously onto each tartlet. Did yours hold its shape cleanly? Share below!

Step 7: Drizzle remaining dulce de leche over the cream in thin lines. Use room-temperature caramel for this — cold caramel won’t flow. Then scatter grated dark chocolate over the top and finish with a small pinch of sea salt on each tartlet.

Step 8: Serve immediately, or within 20 minutes of assembly. The base holds its texture best when the tartlets go straight to the table.

Ways to Change It Up

Try this: Swap the digestive biscuits for gingersnaps. The spice underneath the caramel is sharp and strange in a way that actually works.

Try this: Add a tablespoon of instant espresso powder to the whipped cream before whipping. It turns the cream slightly grey and not visually appealing — but the flavor against the banana and caramel is worth it.

Try this: Replace the dark chocolate garnish with toasted coconut flakes. Different texture, less bitter, and it holds up slightly longer without going soft.

Which would you go for? Drop it in the comments.

How to Serve It

Straight from the mold onto a plate, with a small sharp knife at the table for cutting. The base cracks cleanly when it’s been baked and cooled properly.

Alongside a very bitter espresso. The sweetness of the caramel and banana needs something to push back against it, and coffee does that better than anything else I’ve tried.

On its own, eaten standing at the counter, straight after assembly. Honestly that’s when it’s best — before anyone else gets there.

What would you pair it with?

Storing It Without Ruining It

Assembled tartlets do not store well. Full stop. The base absorbs moisture within an hour and by the next morning it’s a different texture entirely — not bad, but not what this is supposed to be.

What does store well: the components separately. Baked, cooled bases can sit in an airtight container at room temperature for up to 2 days. Whipped cream keeps in the fridge for about 24 hours before it starts to weep. Dulce de leche keeps refrigerated for weeks.

If you need to freeze anything, freeze the baked bases only — wrapped tightly, up to one month. Thaw at room temperature for 30 minutes before assembling. Do not freeze assembled tartlets. The banana and cream do not survive it.

Reheating doesn’t apply here. These aren’t served warm. If you’ve assembled them and they’ve been in the fridge — maybe you made them slightly too far ahead — serve them cold and just accept that the base will be softer than you’d want it to be.

Mistakes I Made So You Don’t Have To

I once assembled all four tartlets an hour before guests arrived, refrigerated them thinking that would buy time, and pulled them out to find the bases had gone completely soft from the cold caramel sweating against the biscuit. Not inedible. Just not what I made.

I used slightly underripe bananas on the second attempt because that’s what I had. They don’t soften enough under the cream — you get a starchy, almost waxy bite where there should be something yielding and sweet. The ripeness of the banana matters more than it seems like it should.

The cream broke once. I was whipping it without paying attention and went past soft peaks into something grainy and slightly separated. I kept going thinking it would come back together. It didn’t. I served it anyway and didn’t mention it. Nobody noticed — but I noticed.

Did something like this happen to you?

Questions I Actually Get Asked

Can I use store-bought caramel sauce instead of dulce de leche?
Yes, but the texture is different — most store-bought caramel sauces are thinner and will pool rather than hold a layer. If that’s what you have, refrigerate the tartlets for 10 minutes after spreading the caramel before adding the bananas. And yes, it depends on the specific sauce; some are closer in consistency than others.

Can I make these without tartlet molds?
I tried using a muffin tin once, and the bases came out fine but the proportion of base to filling was off — too deep, not enough caramel and cream per bite. Use proper tartlet molds if you can. But if you can’t, shallow molds work better than deep ones.

How far ahead can I prep the bases?
About 2 days at room temperature in an airtight container. After that they start to taste stale. I tried stretching it to 3 days once — not worth it. Bake fresh if you have time.

My caramel slid off the base. What happened?
Almost always temperature. Either the base was still warm, or the dulce de leche was too soft. Both cases have the same fix: everything cold before assembly. It depends on your kitchen too — in a warm room this happens faster than you’d expect.

Can I double the recipe?
Easily. The only thing to watch is oven space — if your biscuit bases are crowded, they steam slightly instead of baking dry and the texture suffers. Give them room. 8 tartlets fit on two standard baking sheets without crowding.

Does the dark chocolate have to go on top? Can I mix it into the cream?
You can, but it sinks. I tried folding grated chocolate into the whipped cream before piping and most of it ended up at the bottom of the piping bag. Grate it on top right before serving — that’s the only way it actually stays visible and adds texture rather than disappearing.

Which answer helped you most?

Where I’ve Landed With This

I’ve made these tartlets about nine times across three months, not because I was perfecting a recipe for a blog but because they kept getting requested.

That said — I still haven’t solved the timing problem to my satisfaction. Assembling right before serving works, but it requires everything to be prepped and staged, and that’s a different kind of effort than it looks like from the outside.

The flavor combination doesn’t surprise me anymore. Banana, caramel, cream, salt — it’s a known quantity. What still gets me is the texture when the base is right: that dry, slightly sandy crunch against the soft caramel and the yielding banana.

It only lasts about 15 minutes before the base starts changing.

Will you make this soon?

I’m already thinking about whether a thinner base — pressed thinner, baked a minute longer — would hold up better. I haven’t tried it yet. That’s the next batch.

Happy cooking! —Marina Caldwell
