Ingredients

Makes about 3 cups

1 cup all-purpose flour
1/2 cup light brown sugar
1/2 teaspoon baking powder
1/2 teaspoon ground cinnamon
1/4 teaspoon kosher salt
3/4 cup old-fashioned oats
1/2 cup (1 stick) unsalted butter at room temperature, cut into pieces
  1. Step 1

    Preheat oven to 375°F. Whisk flour, brown sugar, baking powder, cinnamon, and salt in a large bowl. Add butter and work into dry mixture with your fingertips until pea-sized lumps form. Add oats and mix with your fingertips until clumps form; it should look like crumb topping. Chill 15 minutes.

    Step 2

    Transfer mixture to a parchment-lined sheet tray and bake 8 minutes. Using a metal spatula, stir and toss crumble. Rotate tray and continue to bake until crumble is dark golden brown, about 8 minutes more. Let cool.

  • Everyone loved this crumble when I served it over blueberry-peach pie filling. It was nice that everyone could sprinkle on as much as they wanted. For one person it needed to be gluten-free so I substituted KAF gluten-free flour, which is probably why it took quite a bit longer than the recommended time to get golden and crunchy. I could see it was not done after 16 minutes, so I turned off the oven and left it in there. After about 12 minutes it was perfect. I did use a very heavy baking pan so that also may have made it take longer to bake. Also added half a cup of chopped pecans. I made it in a food processor so it went together very quickly. Will definitely make again.

  • I made this crumble to replace the cake in a truffle recipe and it was perfect. The crumble was just sweet enough to compliment the flavors of the various fruits, cream and pudding I used in the recipe
