Add the almond flour and salt to a bowl and whisk to blend together.
Add the maple syrup and olive oil to the bowl and use a spatula or fork to combine the ingredients to blend well and form a ball of dough. You can divide the dough into four balls so it's easier to roll each ball of dough.
Cover the dough and chill it in the refrigerator for 15 minutes or until ready to use.
Prepare a baking sheet with parchment paper.
Preheat your oven to 325 ℉.
Use two pieces of parchment paper to roll a ball of dough into a flat layer about ⅛ to ¼ inch in thickness.
Cut the cookies out. You'll want to make sure you have half the cookies with the center cut out and half without.
Place the cookies on the baking sheet and bake for 10 minutes.
Cool the cookies and then spread half with jam and combine to make Linzer cookies.
Store sealed at room temperature for a day or so or store in the refrigerator for a few weeks.
