BJ's Easy Blackberry Cobbler

Ingredients

• cooking spray
• 5 cups fresh blackberries
• 0.5 cups white sugar
• 2 tablespoons lemon juice
• 1 package lemon-poppy seed muffin mix , 14.5 ounce
• 0.33 cups milk
• 1 large egg
• 1 teaspoon ground cinnamon
• 1 cup brown sugar
• 0.5 cups butter , room temperature

Instructions

1. 1

   Preheat the oven to 375 degrees F (190 degrees C). Coat a 9x9-inch baking pan with cooking spray.

2. 2

   Spread blackberries in the prepared baking pan; sprinkle with white sugar and drizzle with lemon juice. Combine lemon-poppy seed muffin mix, milk, egg, and cinnamon in a bowl; stir until moist (it's okay to leave lumps in batter). Pour batter over blackberries.

3. 3

   Beat brown sugar and butter together in a bowl with an electric mixer on medium speed until mixture resembles coarse crumbs; spread over batter.

4. 4

   Bake in the preheated oven until topping is golden, and blackberries are bubbling, about 1 hour. Cool before serving, 20 minutes.
