This mixed berry cobbler is a taste of summer in every bite. A sweet filling made with blueberries, blackberries, and raspberries is topped with classic cobbler dough. Then, the whole thing is baked until sweet and bubbly on the inside and golden on the outside. It’s absolute perfection in every bite!

Cobbler is the quintessential summer dessert. When our favorite fruits come into season, the best thing we can do with them is turn them into cobblers. I love them, and I make all kinds. From classic peach cobbler or strawberry rhubarb cobbler to sweet and easy pear cobbler, I love turning all types of fruits into this summer favorite. My newest addition is this mixed berry cobbler. It combines three different berries into one sweet filling that absolutely screams summer.

Ingredients
Filling
- Berries: A mix of blackberries, blueberries, and raspberries creates a sweet, tangy filling that gets bubbly and thick as it bakes.
- Sugar: Sugar macerates the berries, so they get juicy before baking, then adds so much sweetness to the filling.
- Lemon Juice: Lemon juice adds a subtle citrus note and enhances the berry flavors.
- Cornstarch: Cornstarch thickens the filling as it bakes.
Topping
- All-Purpose Flour: Basic all-purpose flour with some salt and baking powder creates a tender, fluffy topping when combined with the other ingredients.
- Cold Butter: Cubed, cold butter cut into the flour helps create the classic cobbler texture.
- Boiling Water: Boiling water mixes the ingredients quickly, avoiding excess mixing and gluten. It also enhances the leavening action of the baking powder to make the cobbler topping extra fluffy.

Flavor Variations
- Fruits: You can use your favorite sliced fruits like apples, peaches, pears, and plums for the filling.
- Berries: Strawberries, boysenberries, or any of your other favorites work well in this filling.
- Cinnamon: A little cinnamon adds a warm, earthy note that works so well with the berries.
Instructions
Filling
- Rinse the berries and combine them with the other filling ingredients in a medium bowl. Let the mixture stand for a few minutes to begin to macerate.
- Pour the mixture into a deep 9×13 baking dish or a 3-quart baking dish sprayed with nonstick spray.
Topping
- Whisk the dry ingredients in a medium mixing bowl. Then, use a pastry blender or fork to cut the cold butter into the mixture until it resembles coarse crumbs.
- Pour the boiling water into the mixture and stir until blended.
- Spoon the mixture over the filling and spread it into an even layer.
- Bake uncovered until the topping is golden brown.
- Cool the cobbler to warm and enjoy!

Tips
- Cube your butter and chill it in the fridge until ready to use. This ensures it’s as cold as possible when cut into the flour.
- Bring your water to a full, rolling boil before pouring it into the flour mixture. This ensures the topping mixes thoroughly and quickly, resulting in the best texture.
- Be sure to let the berries sit for 5 to 10 minutes so they begin to macerate before you bake them.
- If the crust browns too quickly, loosely cover it with foil to slow down the process.
Storage
Refrigerate this mixed berry cobbler for up to 4 days in an airtight container. For longer storage, chill the cobbler and freeze it for up to 3 months in an airtight, freezer-safe container.
To reheat the cobbler, microwave individual portions at 1-minute intervals until heated through.

Frequently Asked Questions
Berries are small and burst relatively easily. So, there’s no need to cook this filling on the stovetop. It will cook and thicken perfectly in the oven as it bakes.
Adding boiling water to batter allows the ingredients to mix more fully and quickly, eliminating excess mixing. This, in turn, eliminates excess gluten. In addition, the hot water also more fully activates the leavening agent in the batter, resulting in better rise and a more tender final product.
Fresh berries should be firm but not hard. They should have no dark or gray spots on them, and they should never be soft.
