Let Herman stand at room temperature a few hours before baking. Mix Herman, eggs, and oil. Add remaining ingredients. Pour into greased 9-x13-inch pan. Sprinkle topping and glaze (optional). Bake 40–50 minutes at 350 degrees. Check for doneness after 35 minutes. As on other coffee cakes, various toppings are appropriate and some Hermans are glazed; suit to your own taste.
