I highly recommend both — the powdered buttermilk and the recipe.
Just remember to read the directions on the box. Instead of reconstituting the buttermilk, you're supposed to mix the powdered buttermilk in with your dry ingredients and the water with the wet ingredients.
The 1970s were not known for being particularly health-conscious. So it's surprising that this 1978 Quaker Oats ad includes a recipe for a wholegrain topping.
2 cups Quaker Oats (quick or old-fashioned) 1/2 cup butter or margarine, melted 1/3 cup Parmesan cheese 1/3 cup finely chopped nuts, wheat germ or un-processed bran, if desired 1/4 teaspoon onion or garlic salt
Combine all ingredients; mix well. Bake in ungreased large shallow baking pan in moderate oven (350˚F) 15 - 18 minutes. Cool; store in tightly covered container in refrigerator. Makes about 3 cups of topping.
Add-a-Crunch Crescent Dinner Rolls
Separate one 8 oz. pkg. refrigerated crescent dinner rolls into triangles. Brush 1 side of each triangle with melted butter; sprinkle with about 1 tablespoon Savory Add-a-Crunch. Roll up; brush tops with melted butter. Sprinkle tops with Savory Add-a-Crunch. Bake according to crescent dinner roll package directions. Makes 8 rolls.
