Preheat oven to 350 degrees F.
I bake on my favorite perforated baking mats to eliminate any chance of spread, for even baking and pretty undersides of our cookies!
In your mixer bowl (or large bowl with hand-mixer) cream butter and sugar until smooth, at least 1 minute
Beat in lemon emulsion and egg
In a separate bowl, combine baking powder, salt and flour. Add to wet ingredient mixing bowl a little at a time.
Mix until thoroughly blended.
Chilling the dough is not necessary! I have tried many different ways of rolling out dough and always come back to the old-fashioned way; a sheet of wax paper that’s been floured.
I usually divide the dough into 3 chunks and roll out each onto a floured surface and cut. In my experience, this dough works best for cookies at 1/4″ thick. I use my Joseph Joseph rolling pin which does the measuring for me – genius!
Bake at 350 for 7-8 minutes, depending on size of cookie. I also suggest baking similar-sized cookies together.
Cool cookies on cookie sheet until firm enough to transfer to cooling rack.
