Preheat Oven: Start by preheating your oven to 350°F (175°C) so it’s nice and hot when the cobbler is ready.
Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
Combine Wet Ingredients: In a separate bowl, mix the whole milk, melted butter, and vanilla extract together until smooth.
Combine Mixtures: Gradually add the wet mixture into the dry ingredients, stirring until just combined. Don’t overmix; it should be lumpy but well incorporated.
Pour and Spread: Pour the batter into a greased baking dish, spreading it evenly.
Sprinkle Cinnamon Sugar: Sprinkle the cinnamon sugar mixture generously over the top, giving it that classic snickerdoodle flavor.
Bake: Place in the preheated oven and bake for 30-35 minutes until golden brown on top. A toothpick should come out clean when inserted in the middle.
Cool and Serve: Allow the cobbler to cool for a few minutes before serving. It’s heavenly warm, topped with ice cream or whipped cream!
