Preheat the oven to 375°F (190°C). Line two muffin pans with 18 muffin liners.
Prepare the crust. Place all the crust ingredients in the bowl of a food processor fitted with the S-blade and pulse for 15 seconds or until there are no large chunks of nuts left. The nuts should be 1/8" or smaller in size.
1 1/4 cups (125 grams) finely ground blanched almond flour, 1 cup (110 grams) pecans, 4 teaspoons (12 grams) coconut flour, 5 tablespoons (70 grams) unsalted butter, 1/4 cup (50 grams) coconut sugar, 2 teaspoons cinnamon, 1/8 teaspoon salt
Press 20 grams, about a rounded tablespoon, of dough onto the bottom of the each liner. Try to press it in the nooks and crannies of the muffin liner.
Bake for 7 minutes or until golden brown. Let cool for at least 20 minutes while preparing the rest of the recipe. Don't skimp on the cooling time or the caramel may leak through.
Place the chopped pecans on a baking sheet and roast for 4-6 minutes or until starting to smell toasty. They burn quickly so keep a close eye on them. Remove from the oven.
Prepare the caramel. Heat the sugar, cream, butter, vanilla and salt in a heavy bottom saucepan (do not use non-stick) over medium heat.
3/4 cup (180 grams) dark brown sugar, 2/3 cup (160 ml) whipping cream, 7 tablespoons (98 grams) unsalted butter, 1 teaspoon vanilla, 3/8 teaspoon salt
Stir until combined and then simmer for 8 minutes. Do not stir. If needed, tilt the pan to redistribute the mixture.
Remove from the heat. The caramel will be quite thin at this point. Let it cool for 20 minutes or until considerably thickened and just barely pourable. Stir in the nuts and then spoon about 2 tablespoons of caramel pecan mixture onto the top of each baked crust.
2 1/2 cups (275 grams) pecans
Place the pans in the refrigerator for 2-3 hours or until the caramel has firmed up.
Serve cold or at room temperature. These can be left at room temperature for 8 hours.
Refrigerate in an airtight container for up to 4 days.
