1 – Sift flour, baking powder, and salt into a bowl; set aside. (side note I haven’t forgotten to tell you about oven temps – this comes later in step 3 as the batter needs to sit for some time)

2 – Put eggs, egg yolks, granulated sugar, vanilla, lemon zest and lemon juice in a bowl. Mix with an electric/hand mixer on medium-high speed until pale and thickened, about 5 minutes. Mix in butter.

3 – Using spatula, fold flour mixture into egg mixture. Let rest 30 minutes HERE is where you preheat your oven to 400 degrees.

4 – Pour batter into prepared pans, filling the molds 3/4 full.

5 – Bake cookies, rotating pans halfway through until edges are crisp and golden, about 6-8 minutes.

6 – Let cookies cool slightly in pans on wire racks.

7 – Invert, and unmold. Dust with confectioners’ sugar, if desired
