01 - Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a large bowl, whisk together all-purpose flour, crushed ginger snap cookies, baking powder, baking soda, salt, ground ginger, cinnamon, and cloves until evenly blended.
03 - In a separate medium bowl, whisk pure maple syrup, packed light brown sugar, whole milk, melted unsalted butter, eggs, and vanilla extract until fully incorporated.
04 - Pour wet ingredients into dry ingredients and stir gently just until combined; do not overmix. A few small lumps are acceptable.
05 - Divide batter evenly among prepared muffin cups, filling each about three-quarters full.
06 - Sprinkle tops of batter with coarsely crushed ginger snap cookies and optional turbinado sugar.
07 - Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
08 - Allow muffins to cool in tin for 5 minutes, then transfer to a wire rack to cool completely before serving.
