Preheat oven to 375F and line a small baking sheet with parchment paper.
In a food processor, pulse pecans a couple of times until finely chopped.
In a small saucepan over medium heat, add butter, sugar and vanilla extract. Melt ingredients together until bubbly, reduce heat to simmer. Cook about 2-3 minutes. Remove from heat.
Add pecans, almond flour, cinnamon, cornstarch and salt to the caramel. Stir until combined well. Spread out thinly on parchment paper. (Mix turns into a paste, this is normal. Spread it out the best you can!)
Bake for 6-7 minutes until bubbling a little and very slightly browned on the edges.
Remove from oven and sprinkle chocolate chips on top. Put back in oven for 1-2 minutes and then spread the chocolate evenly over pecans.
Sprinkle with salt and sprinkles.
Freeze until chocolate fully hardened. Cut or break into pieces.
Enjoy!
