Pre-heat oven to 375. Wash, peel and slice pears, then add 1 tablespoon brown sugar, mix and set aside.
Combine almond flour, finely chopped walnuts and sugar in a large bowl. Then add the butter and mix until crumbly.
Press 1 1/2 cups of the crumb mixture in an even layer into the bottom of a 9 inch spring-form pan.
Then place the sliced pears on top working from the inside to the outside perimeter.
Sprinkle the rest of the crumb mixture over the pears. Place pan on foiled lined baking sheet.
Bake for 25-28 minutes, or until lightly browned. Remove from the oven and let cool for 5 minutes. Then release spring-form pan, slice and enjoy!
