  • 1 cup sifted all purpose flour spooned and swept carefully
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 cup pumpkin canned
  • 2 large eggs
  • 3/4 cup sugar
  • 1/2 cup vegetable oil
  • 1/3 cup toasted walnut pieces

Boiled Frosting:

  • 1 1/2 tablespoons flour
  • 1/2 cup milk
  • 8 tablespoons butter salted add pinch of salt if using unsalted
  • 1/2 cup granulated sugar
  • 1 teaspoon vanilla extract


  • Preheat oven to 350 degree F. Line a 9 inch metal pan with nonstick foil or spray with cooking spray.
  • Stir or sift together the pre-sifted flour, baking powder, baking soda, cinnamon and salt. Set aside.
  • In another bowl, stir together pumpkin, eggs, sugar and oil. Beat until well mixed.
  • Stir flour mixture into pumpkin mixture. Stir in toasted walnuts. Spread batter in pan and bake for 25 minutes or until cake springs back and seems done.
  • Let cool on a rack While cake is cooling, begin preparing the icing.
  • In a small but heavy saucepan, whisk together flour and milk. Turn heat to medium and cook, whisking constantly, until mixture thickens and becomes gravy-like. Remove from heat and let cool completely.
  • In a mixing bowl, beat butter and sugar until fluffy. Beat in vanilla. Beat in cooled milk/flour mixture then beat and beat and beat with an electric mixer until the graininess goes away.
  • Spread over bars. Cut however many you want.....I cut 16 really small pieces, but 12 is more practical.
