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!
Cream butter and sugar until smooth, about 2 minutes. No need to excessively cream as it can lead to cookie spread.
Beat in cake batter flavoring, vanilla and egg, until combined.
In a separate bowl, combine flour, baking powder and salt. Add to wet ingredient mixing bowl a little at a time.
Mix until thoroughly blended. Dough should be pulling away from the bowl.
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 has 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! If you prefer thicker cookies, you'll just want to adjust your baking time.
I dip my stamp in loose flour and tap off the excess. I re-flour my stamp after every 1-2 cookies.
Use the cookie stamp to gently press down into the dough to create the design.
You can use a cookie cutter before or after stamping (depending on style) to cut your dough.
Bake at 350 degrees for 7-8 minutes for soft, chewy cookies or bake longer for a crispier cookie.
Let cookies set on cookie sheet until firm enough to transfer to cooling rack.
