This decadent pecan pie lasagna transforms the classic Southern pie into a spectacular layered dessert that will impress at any gathering. Each carefully crafted layer builds upon the next to create a symphony of textures and flavors that dance across your palate with each bite.
I first created this when looking for an alternative to traditional Thanksgiving pies. The moment my grandmother tasted it, she declared it even better than her beloved pecan pie recipe that had been in our family for generations.
Ingredients
- Tea biscuits or digestive cookies: Form the perfect crumbly foundation with just the right amount of sweetness
- Melted butter: Binds the crust and adds richness look for European style butter for extra flavor
- Brown sugar: Brings deep molasses notes that perfectly complement the nuts
- Chopped pecans: Provide the star flavor choose fresh nuts and toast them lightly before using
- Mascarpone cheese: Creates a velvety cream layer that balances the sweetness
- Heavy cream: In multiple layers adds decadence and helps create distinct textures
- Gelatin: Stabilizes the cream layer for perfect slices use quality unflavored gelatin
- Vanilla extract: Enhances the nutty flavors buy pure vanilla for the best results
Step-by-Step Instructions
- Prepare the Crust:
- Process the biscuits in a food processor until they become fine crumbs with no large pieces remaining. Mix with melted butter and brown sugar until the mixture resembles wet sand and holds together when pressed. Press firmly and evenly into your baking dish, ensuring there are no gaps or thin spots. Refrigerate for a full 30 minutes to set completely.
- Create the Nut Layer:
- Melt butter over medium heat in a heavy bottomed saucepan until it begins to foam. Add brown sugar and stir continuously as it dissolves completely. Pour in cream and add salt, then simmer for exactly 3 minutes until the mixture thickens slightly but remains pourable. Remove from heat, add vanilla and fold in the chopped pecans, ensuring they're evenly coated. Pour immediately over the chilled crust and spread into an even layer.
- Whip the Cream Layer:
- Dissolve gelatin in cold water and let it bloom for 5 minutes until it becomes translucent. Microwave for 10 seconds until liquid but not hot. Whip heavy cream with powdered sugar starting on low speed and gradually increasing to high until stiff peaks form but the cream still looks glossy. In a separate bowl, whisk mascarpone until smooth, then gently fold in the cooled gelatin mixture. Combine the mascarpone mixture with the whipped cream using a folding motion to maintain air and volume.
- Create the Caramel Topping:
- Add sugar to a completely dry, heavy bottomed pan and heat over medium heat without stirring. Watch carefully as it melts and turns amber, gently swirling the pan occasionally. Once fully melted and golden, add butter and whisk vigorously as it bubbles. Carefully pour in cream standing back as it will splatter and whisk until completely smooth. Allow to cool for exactly 15 minutes before pouring over the cream layer.
- Final Assembly:
- Pour the slightly cooled caramel over the cream layer, tilting the dish to create an even coating. Arrange whole pecans in a decorative pattern on top and optionally place biscuits around the edge. Refrigerate for at least 3 hours or preferably overnight to allow all layers to set completely.

The brown sugar caramel brings me back to my childhood when my mother would make stovetop pudding with that same deep, rich sweetness. I remember the first time I served this at a family gathering, my uncle who claimed to dislike desserts had three slices and then asked for the recipe.
Perfect Temperature Matters
Allow the dessert to sit at room temperature for exactly 10 minutes before serving. This brief warming period softens the caramel just enough to create the perfect texture while keeping the cream layer firm. The contrast between the cold cream and slightly warm caramel creates an unforgettable sensory experience.
Successful Substitutions
The versatility of this recipe allows for numerous adaptations. For a lighter version, replace mascarpone with Greek yogurt strained overnight to remove excess moisture. Those avoiding gelatin can substitute agar agar powder dissolved according to package directions. Allergic to pecans? Walnuts or hazelnuts work beautifully, though each brings its own unique flavor profile to the final dish.
Serving Suggestions
While this dessert stands perfectly on its own, a few thoughtful accompaniments can elevate it further. Serve with a small scoop of vanilla bean ice cream for temperature contrast, or add a drizzle of warm chocolate sauce for those who love chocolate with their nuts. For a more sophisticated presentation, offer small portions alongside tiny cups of espresso or bourbon for adults.
