Easy Banoffee Slab Pie

Recipe Ingredients

Here’s a look at the ingredients you’ll need for this Easy Banoffee Slab Pie.

Sugar Cookie Mix: One package of sugar cookie mix makes the easiest pastry-like crust that perfectly complements the sweet layers of dulce de leche, ripe bananas, and whipped cream.

Dulce De Leche: Essentially a milk caramel, dulce de leche can be purchased in a can in most grocery stores. Some recipes call for making your own from a can of sweetened condensed milk but buying prepared dulce de leche saves a ton of time without sacrificing flavor.

Ripe Bananas: It’s not really banoffee pie without bananas! Choose a less curved bunch of bananas for more even slices.

Whipped Cream: Lightly sweetened whipped cream not only provides that creamy topping, but it acts as a barrier to protect the bananas from browning. 

Chocolate Bar: This final garnish adds just a hint of chocolate flavor without overpowering the other ingredients.

Other Ingredients You'll Need: All-purpose flour, melted butter, cream cheese, powdered sugar, and a touch of salt.

How to Make Easy Banoffee Slab Pie

Here are our best tips for making sheet pan banoffee pie. See the full recipe for complete instructions.

1. Make the Cookie Crust

Combine the cookie mix with flour and a pinch of salt. Using a wooden spoon or firm spatula, stir in the melted butter. Mix until combined and there are no longer any dry streaks of flour or cookie mix in the dough.

2. Press the Dough into the Pan

Scatter and crumble clumps of dough over the bottom of the baking pan then press in an even layer to form a crust. Poke holes in the crust with a fork, called docking, to create vents for the steam to escape as the crust bakes.

3. Bake the Crust

The crust should be golden brown all over. It will firm up into a shortbread-like pastry as it cools.

4. Layer on the Dulce de Leche and Bananas

Spread the dulce de leche onto the baked and cooled crust. Then nestle sliced bananas on top of the dulce de leche, shingle the slices for bananas in every bite.

5. Make the Whipped Cream

Beat heavy cream with a little bit of cream cheese to create a stabilized cream that won’t deflate and will slice more cleanly when serving.

6. Top with Shaved Chocolate

Use a vegetable peeler along the long side of a chocolate bar to shave tiny curls and shards of chocolate over the top of the pie.

Cover the pie with plastic wrap, making sure to press plastic wrap onto any surface with exposed bananas to prevent browning. Store in the refrigerator for up to 2 days.
