  • 1 tsp ground cinnamon
  • 4 tbsp cold unsalted butter, cubed

  1. Preheat oven to 425°F (218°C) and line a muffin tin with liners.
  2. In a small bowl, combine 1/2 cup flour, 1/2 cup brown sugar, and 1 tsp cinnamon. Rub cold butter into the mixture using a fork or fingers until coarse crumbs form. Set aside.
  3. Toss diced apples in a small bowl with 1 tablespoon of the measured batter flour until lightly coated.
  4. In a large bowl, whisk together the remaining flour, baking soda, baking powder, cinnamon, pumpkin pie spice, and salt.

  6. Gently fold the wet ingredients into the dry ingredients using a spatula until just combined; do not overmix.
  7. Gently fold in the flour-coated apple chunks.
  8. Divide the batter among the muffin liners, top with the cinnamon streusel, and bake for 25 minutes.
