How to make homemade Fluffy and Moist Peach Muffins?

Mix the brown sugar, granulated sugar, cinnamon, and melted butter together in a small bowl until combined. Add the flour and use a fork to gently mix until the crumbs form. Set aside.

Whisk the flour, baking soda, baking powder, cinnamon, allspice, and salt together in a large bowl. Set aside.

Beat the butter and both sugars together until smooth and creamy. Add the eggs, yoghurt or sour cream, and vanilla extract. Beat until the mixture is combined and mostly creamy.

Add the dry ingredients and milk to the wet ingredients and beat until no flour pockets remain. Fold in the chopped peaches.

Spoon the batter evenly into each cup or liner, filling each all the way to the top. Spoon crumb topping on each, gently pressing it down so it sticks.

Bake in a preheated oven to 220°C for 5 minutes. Then, reduce the oven temperature to 177°C. Bake for 19 minutes. Allow the muffins to cool for 5 minutes in the muffin pan, then transfer them to a wire rack to continue cooling for at least 15 minutes before unwrapping and eating.

For the icing, whisk all of the icing ingredients together and drizzle over warm or cooled muffins. Enjoy!
