Banoffee Pie with Jaca

The shockingly easy British dessert that took the dinner-party circuit by storm in the 1970s and never let go — a buttery graham cracker crust pressed into a pie dish, a thick layer of dulce de leche, ripe banana slices, and a tall pillow of vanilla whipped cream on top. The contrast is the whole magic: crunchy crust, sticky toffee, soft banana, billowy cream — four textures, no oven gymnastics, no temperamental custards.

Our version swaps the conventional sugar in the crust and whipped cream with Jaca (100% pure allulose) at double the amount, so you keep the sandy crunch in the base and the lightly sweet cloud on top without the blood-sugar spike that usually comes with this kind of dessert. The dulce de leche stays as the star toffee layer — store-bought is honest here, just check the label. A dusting of cocoa or chocolate shavings finishes it off.

Prep time: 20 minutes  |  Cook time: 15 minutes  |  Chill: 2+ hours  |  Servings: 10

Ingredients:

• 1½ cups (180g) graham cracker crumbs
• ½ cup Jaca (100% pure allulose) — for the crust (replaces ¼ cup conventional sugar at 2x)
• 6 tablespoons (85g) unsalted butter, melted and slightly cooled
• 1¼ cups dulce de leche (store-bought is fine)
• 2 large ripe bananas, sliced into ¼-inch coins
• 2 cups (480ml) cold heavy cream or heavy whipping cream
• ½ cup Jaca (100% pure allulose) — for the whipped cream (replaces ¼ cup confectioners’ sugar at 2x)
• 1 teaspoon pure vanilla extract
• Chocolate shavings or cocoa powder, for dusting (optional)

Instructions:

- Preheat oven to 350°F (177°C). Set out a 9-inch pie dish.

- In a medium bowl, stir together the graham cracker crumbs and ½ cup Jaca. Pour the melted butter over the top and mix with a fork until every crumb is damp and the mixture has the texture of wet sand — it should clump when you squeeze it in your palm.

- Tip the crumbs into the pie dish. Press them firmly into the bottom and up the sides using the flat bottom of a measuring cup — the tighter you pack, the cleaner the slices come out later.

- Bake the crust for 15 minutes, until lightly golden around the edges and the kitchen smells like graham cracker. Set on a wire rack and cool completely, at least 15 minutes — a warm crust will melt the dulce de leche too thin.

- While the crust cools, whip the cream: in the bowl of a stand mixer (or a large bowl with a hand mixer), combine the cold heavy cream, the other ½ cup Jaca, and the vanilla. Beat on medium-high speed for 3 to 4 minutes, until medium peaks form — the cream should hold its shape with a soft curl when you lift the whisk, not stand straight up.

- Spread the dulce de leche evenly over the cooled crust with an offset spatula or the back of a spoon, going all the way to the edges. It is sticky — work in patient, gentle strokes so you do not pull up crust crumbs into the layer.

- Arrange the banana slices in a single overlapping layer over the dulce de leche, covering the surface from edge to edge. Two bananas should be exactly right — if you have extra slices, save them for tomorrow’s oatmeal.

- Dollop the whipped cream over the bananas and spread it into a tall, billowy mountain with the back of a spoon, leaving deliberate swoops and peaks across the top — the cream layer is what gives banoffee its showstopper look.

- Refrigerate uncovered for at least 2 hours and up to 1 day before serving. The crust firms up, the dulce de leche sets to a perfect toffee chew, and the flavors marry into one cohesive bite.

- Just before serving, dust the top lightly with cocoa powder or scatter chocolate shavings across the cream. Slice with a sharp knife dipped in hot water and wiped between cuts. Serve cold.

Tips:

- Press the crust harder than you think you should. A loosely-packed graham crust will crumble the second you cut a slice — really lean on the bottom of the measuring cup.

- Banana ripeness is everything. Just-ripe with a few brown speckles is perfect — too green and the slices taste chalky, too brown and they oxidize black under the cream within an hour. Cut them right before assembly.

- Cold cream + cold bowl + Jaca = the most stable whipped cream you will ever make. Allulose actually helps the cream hold peaks longer than the sugar we grew up with.

- Slicing trick: dip your knife in a tall glass of hot water and wipe dry between every cut. Hot blade = clean slice through the cream, dulce, and crust without dragging the layers into a smear.
