Preheat your oven to 350°F (175°C) and line a 9x5-inch loaf pan with parchment paper.

In a mixing bowl, combine melted butter, pumpkin puree, Greek yogurt, eggs, brown sugar, maple syrup, and vanilla extract. Whisk until smooth.

Whisk together flour, baking soda, baking powder, salt, and spices in a separate bowl.

Fold the dry ingredients into the wet mixture until just combined, avoiding overmixing.

Pour the batter into the loaf pan and smooth the top.

Bake for 45-50 minutes until a toothpick comes out clean.

Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack.

Whisk together powdered sugar, maple syrup, and milk until smooth for the glaze.

Pour the glaze over the cooled bread and let it set for 10 minutes before slicing.
