Crockpot Biscoff Cinnamon Roll Casserole

This Crockpot Biscoff Cinnamon Roll Casserole is the ultimate dump-and-go dessert. Quartered jumbo cinnamon rolls are layered with a rich custard made from melted Biscoff cookie butter, heavy cream, and eggs, then slow-cooked until puffy and caramelized.

Finished with a drizzle of vanilla icing, extra melted cookie butter, and a shower of crushed cookies, every spoonful is warm, gooey, and irresistibly spiced. Perfect for brunch, potlucks, or any day that calls for comfort.

Forget complicated baking—this slow cooker casserole comes together in minutes. You only need a few ingredients and a Crockpot to create a dessert that tastes like a bakery masterpiece.

The cinnamon rolls soak up a speculoos custard as they cook low and slow, turning tender and fluffy with crisp, caramelized edges. The final topping of icing and melted cookie butter takes it over the top. Serve it warm with a scoop of vanilla ice cream if you like, though it’s plenty indulgent on its own.

Ingredients

Why this recipe works

Slow cooking is the secret here. The gentle, even heat of the Crockpot allows the cinnamon roll dough to rise and puff without drying out, while the Biscoff custard—made from melted cookie butter, cream, and eggs—soaks into every crevice.

As the casserole cooks, the sugars in the cookie butter and the cinnamon rolls caramelize against the sides of the pot, creating crispy, buttery edges that contrast with the soft, custardy center.

The dump-and-go method means minimal prep and no oven required. By layering the quartered rolls with the custard mixture, you ensure every piece is coated and infused with flavor. The result is a dessert that is both comforting and impressive, with a texture that is part bread pudding, part sticky bun, and wholly delicious. Plus, it’s endlessly customizable—add nuts, chocolate chips, or a pinch of sea salt to make it your own.

Notes and substitutions

Lotus Biscoff cookie butter is the star of this recipe. Its caramelized speculoos flavor—warm notes of cinnamon, brown sugar, and a hint of nutmeg—melds beautifully with the cinnamon rolls.

If you can’t find it, any speculoos spread works, or you can use a smooth peanut butter for a different but equally tasty result. The heavy cream adds richness and helps the custard set; half-and-half or whole milk are fine substitutes, though the texture will be slightly less decadent.

Jumbo cinnamon rolls come in 12.4-ounce cans with eight rolls each. You’ll use two cans for this recipe. If you only have regular-sized rolls, use three cans and check for doneness at 1 1/2 hours. The reserved icing packets are used for the topping, so don’t discard them. A 6-quart slow cooker is ideal; if yours is smaller, reduce the recipe by a third and adjust the cooking time slightly.
