Preparation
In a medium bowl, combine both sugars, the cinnamon, and melted butter. Using a rubber spatula, stir in the flour. The crumb topping will be thick and crumbly. Set aside.
Preheat oven to 425 degrees F. Spray a 12-count muffin pan with nonstick spray. Set aside.
In a medium bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter on high speed until smooth and creamy, about 1 minute.
Add the brown sugar and granulated sugar and beat on high until creamed, about 2 full minutes. Scrape down the sides and bottom of the bowl as needed. Add the eggs, yogurt, and vanilla extract.
Beat on medium speed for 1 minute, then turn up to high speed until the mixture is combined and uniform in texture. Scrape down the sides and bottom of the bowl as needed.
In a large bowl, toss together the flour, baking soda, baking powder, cinnamon, all-spice, and salt. Pour the wet ingredients into the dry ingredients and slowly mix with a whisk.
Add the milk, gently whisking until combined and little lumps remain. Fold in the peaches with a wooden spoon or rubber spatula.
Spoon the muffin batter evenly between all 12 muffin tins.
Fill the muffin tins until they are full all the way up to the top. Press a handful of the crumb topping into the top of each; crumble it with your hands to make some big chunks.
Bake for 5 minutes then keeping the muffins in the oven, lower the oven temperature to 350 degrees F and bake for 15 to 19 more minutes or until a toothpick inserted in the center comes out clean.
To make the glaze, whisk all of the ingredients together and drizzle over warm muffins.
