Ingredients
5 cups fresh blackberries
1/2 cup white sugar
2 tablespoons lemon juice
1 (15.8 ounce) package lemon-poppy seed muffin mix
1 egg
1/3 cup milk
1 teaspoon ground cinnamon
1/2 cup butter at room temperature
1 cup brown sugar
Cooking spray
Directions
Preheat your oven to 375°F (190°C). Lightly coat the inside of a 9x9-inch baking pan with cooking spray.
Spread the fresh blackberries evenly across the bottom of the prepared baking pan. Sprinkle the white sugar over the berries and drizzle with lemon juice.
In a medium bowl, combine the lemon-poppy seed muffin mix, egg, milk, and ground cinnamon. Stir the mixture until just combined—it's fine if there are some small lumps remaining in the batter.
Pour the muffin batter evenly over the blackberries in the baking pan.
In a separate bowl, place the softened butter and brown sugar. Using an electric mixer on medium speed, beat the mixture until it resembles coarse breadcrumbs.
Distribute the crumb topping evenly over the batter, covering as much of the surface as possible.
Bake in the preheated oven for 40 to 45 minutes, until the topping is golden brown and the filling bubbles slightly at the edges. Remove from the oven and allow to cool for 10 to 15 minutes before serving.
Comments
This cobbler leans on a box muffin mix, which trades a bit of homemade character for real convenience and consistent results—a fair tradeoff for a weeknight dessert. Blackberries are reliably stocked at Harris Teeter, Food Lion, Publix, Walmart, and ALDI year-round (though peak season is June through August when price dips), and every other ingredient is a standard pantry staple or dairy item found everywhere. The stated 95 minutes is honest for baking time, but assumes blackberries are already prepped; add 5 minutes if you're washing and picking through them. This feeds 10 as a dessert course, reheats well in the oven, and asks nothing fussy of the cook—it's a solid, unfussy family dessert with no second stops required.
