Instructions
Preheat the oven to 390F and line 9 muffin cups with paper liners.
To make the crumble topping, mix together the oats, brown sugar and cinnamon in a small bowl. Add the cold butter pieces and use your fingertips to rub the butter into the oat mixture until you have an even crumb with pea-sized pieces of butter. Pop the bowl into the refrigerator while you make the muffin batter.
Prepare the peaches by peeling the peaches, if fresh. Cut peaches into 1/2-3/4-inch chunks. Set aside.
In a small bowl or a measuring cup, whisk together the oil, egg, milk and vanilla. Set aside.
Combine the flour, sugar, cinnamon, baking powder and salt in a large bowl or the bowl of a stand mixer fitted with the paddle attachment.
Pour the wet ingredients into the dry ingredients and mix gently, with a wooden spoon or on the lowest speed on the mixer, mixing JUST UNTIL THE FLOUR IS INCORPORATED. Do not over-mix. Add the peach chunks to the batter and stir to combine.
Fill the muffin liners almost to the top with batter. You should get 9 muffins. Top the muffins with the oat topping mixture (you may not need quite all of it). Fill any empty muffin cups 1/2 full with water.
Bake muffins for 18-22 minutes or until a tester inserted into the centre of the muffins comes out clean.
Allow to stand in the muffin pan a couple of minutes, then carefully transfer to a cooling rack to cool completely.
If glazing, allow the muffins to cool completely. Stir together the icing sugar and milk until you have a glaze that easily falls off a spoon. Drizzle over cooled muffins.
