Love these! Had a few issues the first time but found my magic formula - reduce butter and sugar by 1/2 Tbsp per recipe, only just lightly cream butter and sugar until combined, add 1/2 Tbsp flour per recipe, use standard bake, increase temp to 365 to account for elevation to set edges and quickly activate baking soda so flour can set before butter melts and spreads too much. Slightly rounded 1-1/2 Tbsp scoop, only need 2.5 Tbsp rolling sugar per recipe. 12 cookies per pan, 9 minutes in oven, on pan 5 minutes.
