The Linzer torte is the oldest known cake recipe in the world, dating back to 1653 in the city of Linz, Austria. It is so delectable â€“ no wonder it has lasted this long! While this easier cookie version is made with strawberry jam, it can also be assembled with the more traditional choice of raspberry jam.
- Course: Dessert
- Baking powder
- Egg yolks
- kosher salt
- pure vanilla extract
- strawberry jam
- unsalted butter
- Zest from 1 lemon
- Combine the hazelnuts, flour, baking powder, salt and sugar in a food processor. Process until the hazelnuts are finely chopped.
- Stop the machine and add the butter, lemon zest, hard boiled egg yolks and vanilla extract. Process until it comes together into a ball. This happens quickly. Chill for 30 minutes for the dough to firm up slightly. This will make it easier to work with.
- Preheat the oven to 350Â°F.
- Divide the dough into two pieces, one two-thirds of the dough and the other one-third. Press the large piece of dough into the bottom of an 8-inch square pan, evenly pressing it across the pan. (You can put a piece of plastic wrap between the dough and your fingers if you prefer.)
- Spread the strawberry jam on top of the dough.
- Divide the remaining piece of dough into 5 or 6 sections. On lightly floured board roll the dough into strips Â¼ inch wide. Diagonally place the strips on top of the jam in a lattice pattern. You can piece together strips. Bake for 25-30 minutes until the jam is set and the crust is golden brown. Cool completely and then cut into 2-inch bars.
