After discussing one of our new favorite Maida Heatter recipes, Big Surs, Sue and I moved onto the topic of how the baking sheet one uses affects the crispiness of cookies. Sue typically uses AirBake cookie sheets to avoid burnt bottoms. To see how it affected crispness, Sue baked her usual Snickerdoodles on a regular flat cookie sheet. Success! They were definitely crisper. Alas, this test was not so scientific because she also chilled the dough.
So technically the results suggest that if you chill the dough AND bake on a non-AirBake cookie sheet, cookies may be crisper. Want a better answer? Bake some Snickerdoodles for yourself! Here’s the recipe Sue uses for very delicious and crispy Snickerdoodles.
