Combine dough ingredients together by hand. Place in the refrigerator for 30 minutes.
On a floured surface, roll out dough into a 10 to 11-inch circle. Place dough on a sheet of baking paper.
Smear the apricot jam over most of the dough.
Lay the apple slices slightly overlapping in a circle, leaving a 2-inch border. Fold up the edges of the dough over the fruit and pinch into pleats.
Combine crumbs ingredients together with your fingers forming coarse crumbs.
Spray border with nonstick cooking spray and sprinkle crumbs generously over dough and fruit. At this point you can freeze it as-is. When ready to bake, just defrost and bake.
Bake at 400°F for 55-60 minutes.
Notes
Make them mini! Divide dough into 5-6 parts to create individual apple galettes.
