Instructions
Crust
Toast the nuts for 15 minutes at 325F, cool and reserve. Grind ⅓ of the nuts to a meal in a spice grinder or food processor.
For the crust, whip the sugar and butter until pale, then add the egg and whip until incorporated, about 4-5 minutes on high, scraping down the bowl occasionally.
Mix or sift the flour, baking powder, salt and cinnamon.
Add the flour to the egg mixture and work into a smooth dough.
For the most even bake, allow the dough to hydrate overnight, vacuum sealed or wrapped in cling film in the fridge (optional). Press the dough into a 9x9 baking pan or similar lined with parchment, making it as even as you can. Pierce the dough all over with a fork to ensure even rising.
Bake the crust for 15 minutes at 375F, then remove and cool. Turn the heat down to 350F.
Filling
Meanwhile, bring the maple, brown sugar, butter, cream and vanilla to a boil in a small pot and cook at a rapid boil for 3 minutes.
Turn the heat off and allow to cool until it’s around 100F or 30 minutes. The syrup needs to be cool enough to not cook the eggs.
Beat the eggs into the maple mixture then pour onto the crust.
Baking
Bake the bars for 30 minutes, or until the filling is just barely set and moves as one. This should be just under 200F if you check it with a thermometer.
At this point it may still seem slightly liquid in the center-this is ideal and ensures they’ll be fudgy in the center. As the bars cool they’ll be easier to cut.
Add a generous sprinkle of crunchy salt to the top before the bars cool.
Cool the bars completely to ensure the filling’s set, then cut into small 2 inch squares and serve. Great with a cup of unsweetened coffee.

Notes
Some of the older women at church may look down on it, but baking powder gives the bars a nice lift and gives the filling space to soak into. For a more traditional, denser crust omit the baking powder and egg and double the butter in the crust for a flaky shortbread consistency.
