1-First step: preheat and melt the butter Start by preheating your oven to 350 degrees F. While the oven heats, slice 6 tablespoons butter into pieces and place them in a 9×13 inch baking dish. Put the dish in the oven while it preheats so the butter melts evenly. Once the butter is melted, carefully remove the dish and set it aside.

2-Second step: mix the blueberry filling In a medium bowl, combine 4 cups blueberries, 1/2 cup granulated sugar, and 1 teaspoon lemon zest. Stir gently so the berries stay mostly whole. The sugar will start pulling out some juice, which is what you want for a juicy filling.

3-Third step: make the batter In another bowl, combine 1 cup flour, 1 cup sugar, 2 teaspoons baking powder, and 1/4 teaspoon salt. Stir these dry ingredients together so the baking powder spreads out evenly. Then pour in 3/4 cup milk and mix just until combined. The batter should look smooth but does not need to be overmixed.

4-Fourth step: assemble the cobbler Pour the blueberry mixture evenly over the melted butter in the baking dish. Do not stir. The layers should stay separate at this point because the butter helps the topping rise around the fruit as it bakes. Next, drizzle the batter over the blueberries. It does not need to cover every bit of fruit perfectly. Cobbler is meant to look rustic, and those uneven spots help create a lovely homemade texture. Sprinkle cinnamon over the top for a warm finish.

5-Fifth step: bake until golden Bake the cobbler for 35 to 40 minutes, or until the top is lightly golden and the filling is bubbling around the edges. If your oven runs hot, start checking around the 35-minute mark. The fruit should look thick and juicy, and the topping should have a soft golden color.

6-Final step: serve warm Serve the cobbler warm, either on its own or with a scoop of vanilla ice cream on top. The cold ice cream melts into the warm fruit and buttery topping, which makes each spoonful extra comforting.
