Oatmeal Streusel Crumb Topping

Streusel is rough crumb mixture of flour, butter and sugar, then additional ingredients such as spices, chopped nuts or oatmeal are added to the mix, making it a perfect topping to compliment cakes, muffins, pies or sweet breads. I like to use it on cakes, thus eliminating the need for frosting.

I wanted to make my favorite easy Pumpkin Spice Cake to take to a meeting. I knew of one person attending with a nut allergy, so I used oatmeal instead of chopped nuts in the streusel, serving it with a container of whipped topping on the side.

Since I wanted a heartier fall cake for the streusel topping, I used a spice cake mix instead of yellow and added an extra egg to the cake mix.

Oatmeal Streusel Crumb Topping


  • 1 cup brown sugar
  • 1/2 cup flour
  • 1 cup oatmeal (old fashioned works better than quick cooking oats)
  • 1 teaspoon cinnamon
  • 2 shakes salt (about 1/4 teaspoon)
  • 1/2 cup COLD butter


  1. Mix everything but the butter in a medium mixing bowl.
  2. Using a pastry cutter, cut the butter into the flour and sugar mixture until it’s dry looking and a large crumbly mix.
  3. Sprinkle the crumbs over prepared cake or pie.
  4. Bake as directed for your cake or pie or until an inserted toothpick comes out clean. Mine took an extra 5 minutes.
