Preheat oven to 350 degrees F. Line square 8 x 8 baking dish with parchment paper and spray with cooking spray. Set aside.
Make crust: In a medium bowl, add almond flour, cornstarch, cinnamon; whisk to combine. Add coconut oil and maple syrup; stir with spatula until well mixed.
Transfer dough to previously prepared baking dish and flatten with hands and spatula into an even layer. Bake for 15 minutes.
Make pecan pie filling: In the meanwhile, in a large bowl, add eggs, coconut oil, maple syrup, vanilla and cornstarch; whisk until combined. Add pecans and stir to combine.
Make bars: Remove crust from the oven and carefully transfer pecan pie filling on top. Place back in the oven and bake for 15-20 minutes or until firm.
Remove from the oven and let cool on the counter for 30 minutes. Then transfer to the fridge to firm up for at least 4 hours or overnight.
Cut into 9 squares and serve chilled. If you like gooey bars, let them warm up on the counter for 30 minutes before slicing.
Notes
Store: Refrigerate covered for up to 1 week.
Freeze: I like to freeze pecan pie bars on a baking tray (not touching each other) until solid and then transfer them to a freezer safe bag for up to 3 months. Whenever you want one, just pop it out onto the counter or within the fridge to thaw.
Other sweeteners: You can use honey or any other liquid sweetener. I have not tested this recipe with sugar or any other powdered sweetener but it could work (in the dough - as long as it forms, and it the filling - for sure will work).
Cornstarch: It thickens the filling and absorbs the moisture in the dough. You can substitute with arrowroot powder.
Butter: I believe you can use melted butter instead of coconut oil, I have not tested though. Butter makes crust more soft and less crumbly.
Nonstick: This is a sticky recipe. Make sure to line your pan AND spray with cooking spray for easy removal of the sliced bars.
Double the recipe: And use a larger pan to bake them. You could also make two separate batches. Then, freeze some for later!
Don't skip the chill time: These bars need lots of time for set up. Otherwise, they will fall apart.
