Ingredients

  • 1 cup milk If you sub buttermilk, skip the vinegar.
  • 1 ¼ tablespoon vinegar If using buttermilk, skip this.
  • 2 teaspoons vanilla extract
  • 3 tbsp oil any mild veggie oil will work fine.
  • 2 cup oat flour (white also works)
  • 1 cup sugar You can use part sugar and part honey, if you like.
  • 1 ¼ teaspoon baking powder
  • ½ teaspoon salt
  • 2 tablespoons cinnamon

For the streusel

  • ¼ cup oat flour
  • cup brown sugar
  • 3 tablespoons oatmeal
  • ¼ cup oil or melted butter.
  • 1 tablespoon cinnamon

Instructions

  • Preheat oven to 350 F. 
  • Spray an 8 by 8 baking pan and set aside.
  • In a large bowl whisk together the milk, vinegar, vanilla, and oil. Set aside. (the vinegar and milk sitting together will make a buttermilk, skip this if using buttermilk)
  • In a small bowl, stir together the ingredients for the streusel...until crumbly.
  • After the milk mixture has set for about 10 minutes, add the rest of the ingredients (flour, baking powder, salt, cinnamon and sugar). Stir just until mixed.
  • Pour batter into the baking pan.
  • Drop the streusel into the pan by the spoonful and use a knife to drag it around, a bit, in swirls. Or, spread it on the top of the batter. (really, how you do your streusel is a personal preference :). Some people even double the streusel and do both the swirl and top)
  • Bake for between 35-45 minutes, checking after 35. It is done when a knife inserted comes out clean. Serve warm, with butter.
