We just barely made these. They're on the cooling racks. They smell delicious and I am liking to eat them, so even though I do not have a special linzer cookie cutter, I'll keep the recipe anyway. The recipe, I believe, came in the box of Fox Run brand linzer cookie cutters.
1 1/4 c almond flour, or hazelnuts and almonds, ground fine
1 c unsalted butter
2/3 c sugar
2 large eggs
1 t vanilla
2 c AP flour
1 t baking powder
1 t cinnamon
1/4 t salt
1 t lemon zest
powdered sugar for dusting (I haven't used this yet)
1 c jam (the recipe suggests seedless raspberry. We're using guava right now, which is surprisingly not too tropical. The jam needs to be fairly smooth.)
Pre-heat oven to 375. Cream butter and sugar till light and creamy. Add eggs, then vanilla. In separate bowl, mix dries and spices. Add dries to wets, beat to combine. Place in freezer till firm, 30-40 min. Dust a surface with flour, roll dough to about 1/8". Cut even amounts of tops and bottoms. Bake cookies 8 minutes. Cool. Use about 1 t jam per sandwich cookie.
