The Shortcut Custard Base:
The Layers & Topping:
Whisk the base: In a large bowl, whisk together 1 can of sweetened condensed coconut milk and 1.5 cups of ice-cold water.
Add the pudding mix: Sprinkle in 1 box of Vanilla Instant Pudding Mix. Whisk vigorously for 2 minutes until smooth, then chill in the fridge for 5 minutes to set.
Fold in the cream: Gently fold half of your thawed dairy-free whipped topping into the set pudding until it is light and fluffy.
Assemble the Biscoff layers: In your 9x13 pan or glass bowl, lay down a flat, single layer of whole Biscoff cookies. Top them with a layer of sliced bananas, then spread half of the pudding mixture over the top. Repeat the layers one more time: Biscoff cookies, bananas, and the rest of the pudding.
Top and finish: Spread the remaining dairy-free whipped topping evenly over the top. Take 3 or 4 extra Biscoff cookies, crush them into fine crumbs, and sprinkle them generously over the whipped cream.
Chill overnight: Cover and refrigerate for at least 4 to 6 hours (or overnight). Because Biscoff cookies are slightly crispier than traditional wafers, giving them a full night in the fridge ensures they soften perfectly into that dream, cake-like texture.
Pro-Tip for Presentation
Since Biscoff cookies look beautiful, you can stand a few whole cookies upright along the edges of a glass serving bowl before layering, or place a few whole cookies on top of the crushed crumbs right before serving for a bakery-worthy look.
