Healthy Pumpkin Muffins

Preheat oven to 325° and line muffin tin with liners.  In a large bowl, whisk together flours, baking powder, baking soda, salt, and pumpkin pie spice. Add pumpkin, honey, eggs, butter, and yogurt, and mix until combined. Fold in 3/4 cup pecans. Divide batter into muffin liners, then top with remaining pecans and Demerara sugar. Bake until muffins are golden brown and a toothpick comes out clean, about 30 minutes. Let muffins cool in pan, then serve.
