up to 1/2 cup optional mix-ins: chopped walnutsraisins, dried cranberries, blueberries, etc. (I kept it simple and left them out, but feel free to add if you like)
1 1/2tablespoonscoarse sugarsuch as raw (turbinado) sugar or sparkling sugar, for sprinkling on top (optional)
Preheat the oven to 350 degrees F. Lightly grease 10 wells in a standard 12-cup muffin tin with nonstick spray or line with paper liners.
In a large bowl, mix together the applesauce, honey, eggs, coconut oil, and vanilla. In a separate bowl, whisk together the whole wheat flour, baking powder, baking soda, cinnamon, allspice, nutmeg, and sat.
Add the flour mixture to the bowl with the wet ingredients and stir just until combined. The batter will be a little lumpy. Gently stir in the rolled oats and any other desired mix-ins.
Divide evenly among the muffin cups, filling each almost to the top. Sprinkle the tops with coarse sugar, if desired. Bake for 18 to 22 minutes, until a toothpick inserted into the center comes out clean. Remove from the oven and place the muffin tin on a wire rack to cool for 10 minutes, then gently remove the muffins from the pan (run a butter knife around the edges if the muffins are sticking) and let them cool completely on the wire rack.
