Preheat oven to 350 degrees F. Butter a 10-inch cake pan.
In a large bowl, whisk together the eggs, sugar, olive oil, milk, liqueur, orange juice, and lemon zest. Sift together the flour, baking soda, baking powder, and salt. Mix the dry mixture into the wet mixture. Whisk until well blended. Fold in the almonds.
Pour the mixture into the buttered cake pan. Bake for 1 hour. Place on a rack to cool. Run a knife around the edges and place it on a plate. Sprinkle with powdered sugar and serve.
