Chocolate Chunk Oat Cookies with Steel Cut and Old Fashioned Oats

These hearty oat cookies combine three types of oats for incredible texture - ground old fashioned oats in the base, whole oats for chewiness, and steel cut oats for delightful crunch. White whole wheat flour adds subtle nuttiness while chocolate chunks provide rich bursts of cocoa. The result is a cookie that's both satisfying and complex, with layers of oat flavor and varied textures in every bite. Perfect for lunch boxes, afternoon snacks, or cozy evenings with milk.

FAQ

Can I use regular oats instead of steel cut oats?

Yes, you can substitute with rolled oats for a different texture, though you'll lose some of the distinctive crunch that steel cut oats provide.

How do I know when the cookies are done?

Look for lightly golden edges while centers remain soft. They'll continue cooking slightly on the hot pan after removal.

Can I freeze the cookie dough?

Yes, portion the dough and freeze on trays, then store in bags. Bake directly from frozen, adding 1-2 minutes to baking time.
