2 c. toasted hazelnuts, finely ground
2-1/4 c. unbleached all-purpose flour
1 tsp baking powder
3/4 c. granulated sugar
1/2 c. extra-virgin olive oil*
2 large eggs, beaten until frothy
1 TBS freshly grated orange zest
1 tsp pure vanilla extract
Combine toasted hazelnuts, flour & baking powder in medium bowl; set aside.
In large mixing bowl, combine sugar, olive oil, eggs, orange zest & vanilla on low speed until well moistened. Increase to medium speed & mix an additional minute. Add the dry ingredients & mix on low until just combined & dough sticks together.
Spread 2 sheets of plastic wrap on counter; divide dough in half & form into 2 logs about 10 inches by 2 inches. Wrap tightly & place in freezer for 2 hours or overnight.
Preheat oven to 350. Line large baking sheet with baking parchment.
Remove one dough log from freezer; unwrap & slice into 1/4 inches slices. Place on prepared parchment & bake for 11 minutes until dry but not brown. Careful to not overbake. Remove to wire racks to cool; repeat with remaining log (or keep frozen for up to one month for later use.)
Store in tightly covered container at room temperature.
These are perfect after a heavy meal with a cup of coffee or nice glass of red wine.
*Or use orange-infused olive oil if you have it available for a stronger orange flavor.
