Cream together butter and sugar till fluffy. Beat in syrup, then eggs one at a time. Beat in flour gradually. Fold in nuts (optional). Pour into greased cake pan (I use abt 9x13 pan). They do not rise much. Bake at 350 degrees about 30-40 mins. Orig. receipe calls for jelly roll pan-that is 15x10. Cooking time is 25 mins for this size. Pan will be full but they do not rise. Frost with the Frosting for Iowa Brownies receipe to follow. *I use Hersheys Choc. syrup. This is more of a "cake" than a brownie. And is "missing something" without the icing!
