Ingredients
- 2 cups all-purpose flour
- 1 cup rolled oats
- 3/4 cup packed brown sugar
- 1 cup (2 sticks), cold and cubed unsalted butter
- 1/2 cup chopped macadamia nuts
- 3/4 cup Davidson’s plum jam
- 1 tsp baking powder
- 1/4 tsp sea salt
Instructions
- Step 1: Preheat oven to 350°F. In a large bowl, combine 2 cups all-purpose flour, 1 cup rolled oats, 3/4 cup packed brown sugar, 1 tsp baking powder, and 1/4 tsp sea salt.
- Step 2: Add 1 cup cold cubed unsalted butter to the dry ingredients. Using your fingers or a pastry cutter, rub the butter into the mixture until coarse crumbs form.
