The Cookie Paddles are made for medium to thick batters and cookie doughs. The triple whipping action allows the paddles to be effective and efficient. Must be used with the Metal Driver only. When mixing stiff dough or adding heavy ingredients (fruit, nuts and candy) switch to the dough hook after creaming the butter. For double to larger batches also switch to the dough hook before adding the flour. The right speeds to use are 1 to 3. Cookie Paddle tips: ALWAYS used soft butter, for large batches of cookie dough switch to dough hook after creaming the butter & sugar. The Metal Driver is not included. 1 year warranty.
