To make the cake:
Preheat oven to 350°F. Grease a 9 inch bundt pan with butter and flour or nonstick cooking spray.
In a bowl, combine the flour, cinnamon, nutmeg, ginger, salt, baking powder, and baking soda. In another bowl, mix together the eggs, sugar, and milk.
Add the dry ingredients and mix until the mixture just comes together and the dry ingredients have fully incorporated into the wet ingredients.
Fold in the shredded zucchini and chopped pears.
Bake 35-40 minutes or until a toothpick inserted into the center comes out clean. Let cool in the pan for 10 minutes, then invert onto a plate or cake stand and let cool completely.
To make the frosting:
Melt the butter in a small saucepan set over medium low heat. Continue to cook, stirring occasionally, until butter is golden brown and has a nutty aroma, about 10 minutes. Set aside to cool for about 10 minutes.
Add the powdered sugar, 1 tablespoon of the milk and vanilla extract and stir until smooth. Glaze should be thick but pourable. Add more milk if needed. Glaze cake immediately.
Chill in the fridge for 20 minutes to firm up glaze before serving, if desired. Store leftover cake in the fridge for up to 5 days.
