Step 1

Preheat oven to 350ºF. Line a 12-cup muffin pan with foil baking cups, or spray it with nonstick spray.

Step 2

Combine streusel ingredients in a medium bowl. Mix and mash until uniform and crumbly.

Step 3

In a large bowl, combine dry muffin ingredients: whole-wheat flour, sweetener, all-purpose flour, baking powder, cinnamon, baking soda, pumpkin pie spice, and salt. Mix well.

Step 4

In a medium bowl, combine remaining muffin ingredients: pumpkin, egg whites/substitute, butter, almond milk, and extract. Whisk until uniform. Add mixture to the large bowl of dry ingredients, and stir until just mixed and smooth. (Batter will be thick.)

Step 5

Evenly distribute batter among the cups of the muffin pan, and smooth out the surfaces. Top with streusel mixture.

Step 6

Bake until a toothpick inserted into the center of a muffin comes out clean, 18–20 minutes.
