First, plug in your pizzelle maker so it’s nice and hot when you’re ready.
In a medium bowl, whisk 1 ¾ cups of flour, 2 teaspoons of baking powder, and ⅛ teaspoon of kosher salt.
In a bowl, rub 2 tablespoons of lemon zest into the sugar. This awakens the bright citrus aroma. Add 3 eggs and mix until the batter is smooth and starts to thicken.
Stir in the ¼ cup of melted butter, ¼ cup of olive oil, 2 teaspoons of lemon extract, and 1 teaspoon of pure vanilla extract until well combined.
Gently fold the dry mix into the wet ingredients, just until no streaks remain. The batter should feel thick, like cake batter, not runny.
Lightly grease the pizzelle iron. Drop about 1 tablespoon (or a heaping scoop) of batter onto the center of the iron. Close it and cook for 1 to 2 minutes, until the hissing stops and the edges look golden.
Use a silicone spatula to lift the pizzelle onto a wire rack. Let them cool completely to crisp up, don’t stack them too soon!
Once cooled, give your cookies a light dusting of powdered sugar if you're feeling fancy.
