Start by preheating your oven to 350 degrees. Generously grease your deep-dish pie plate or 13x9 inch baking dish with some butter or cooking spray.
In a medium bowl, whisk together the sugar and egg until smooth. Pour in the milk and stir until combined. Add the flour, baking powder, and salt, mixing just until no streaks of flour remain—don’t overmix. Finally, stir in the melted butter until you’ve got a smooth, pourable batter. Spread it evenly into your prepared baking dish, right over the melted butter. No need to stir, just let the magic happen in the oven.
In a clean bowl, toss the blackberries with the remaining sugar and vanilla until they’re nicely coated. Gently spoon them evenly over the batter—don’t stir or press them in. As it bakes, the berries will sink just enough to mingle with the crust while still peeking through that golden top.
Now comes the hard part – waiting! Bake it in your preheated oven for about 40-45 minutes. You'll know it's ready when the fruit is bubbly, and the crust has turned a beautiful golden color.
The final touch? Serve it warm with a generous scoop of vanilla ice cream on top. Trust me, it doesn't get any better than this!
Notes
To make this Blackberry Cobbler recipe gluten-free, you'll need to replace the all-purpose flour with a gluten-free alternative. Here are the adjustments you'd need to make:
Gluten-Free All-Purpose Flour: Substitute the regular flour with a gluten-free all-purpose flour blend. Look for one that substitutes on a 1:1 ratio for regular flour. Brands like Bob's Red Mill or King Arthur Flour have reliable gluten-free blends.
Xanthan Gum: If your gluten-free flour blend doesn't already contain it, you might want to add a bit of xanthan gum to your mixture. This ingredient helps to bind gluten-free baked goods and make them less crumbly. Usually, 1/4 to 1/2 teaspoon would be enough for this recipe.
The rest of the ingredients in the recipe are naturally gluten-free, so no other adjustments are needed. Enjoy your gluten-free Blackberry Cobbler!
