This easy gluten-free blackberry cobbler is a summer favorite you’ll want to make every year when blackberries are at their peak. Juicy blackberries are tossed with sugar, honey, and arrowroot (or cornstarch) and topped with a tender, buttery gluten-free biscuit topping that bakes to a golden finish in about 45 minutes. It works equally well with fresh wild blackberries, marionberries, store-bought berries, or frozen fruit, so you can enjoy this cobbler any time of year.

Simple to prepare yet impressive to serve, this from-scratch gluten-free dessert is satisfying and reliably delicious.

Living in the Pacific Northwest means we’re lucky to have wild blackberries every summer, and this gluten-free cobbler is one of the best ways to use them. There’s something especially satisfying about picking berries and turning them into a warm cobbler the same day.

The sweet, bubbling blackberry filling and the golden biscuit-style topping are a perfect match. Serve the cobbler warm with a generous scoop of vanilla ice cream for the best results.

Whether you use freshly picked wild blackberries, homegrown marionberries, or frozen berries from the freezer, this cobbler is a reliable summer dessert you’ll return to season after season.

Ingredients

Filling:
Blackberries
Granulated sugar
Arrowroot powder or cornstarch
Honey

Topping:
Gluten-free flour
Buttermilk (or substitute)
Eggs
Baking powder
Sea salt
Granulated sugar
Vanilla extract

Instructions

Preheat the oven to 350°F (175°C).

In a large bowl, combine the blackberries, granulated sugar, arrowroot powder (or cornstarch), and honey. Gently toss to coat and set the filling aside while you prepare the topping.

In a mixing bowl, whisk together the gluten-free flour, sugar, baking powder, and sea salt. Add the buttermilk, eggs, and vanilla extract and stir or beat just until the ingredients come together. Avoid over-mixing—the batter should be thick and slightly lumpy.

Pour the blackberry mixture into a greased 2-quart baking dish. Using a spoon, drop generous dollops of the biscuit batter over the fruit, spacing them evenly. Do not spread or press the batter; it will spread and rise as it bakes.

Bake at 350°F for about 45 minutes, or until the topping is golden brown and the filling is bubbling around the edges.

Allow the cobbler to cool for at least 15–20 minutes so the filling can set slightly before serving. Store any leftovers covered in the refrigerator for up to five days.

Supplies

2-quart baking dish, mixing bowls, measuring cups and spoons, and a spoon or scoop for dolloping the batter.

This easy gluten-free blackberry cobbler uses fresh or frozen berries and a simple biscuit-like topping that browns beautifully in under an hour. The result is tender, buttery biscuits over a glossy blackberry filling that’s perfect with vanilla ice cream.

Filling:

• 5 cups blackberries
• 1/4 cup granulated sugar
• 2 tbsp arrowroot powder or cornstarch
• 2 tbsp honey

Topping:

• 2 1/2 cups gluten-free flour
• 3 tsp baking powder
• 1 tsp sea salt
• 1 cup granulated sugar
• 1 cup buttermilk (or substitute)
• 2 large eggs
• 1 tsp vanilla extract

1. Preheat oven to 350°F. Mix blackberries with sugar, arrowroot (or cornstarch), and honey. Set aside.

2. Combine flour, sugar, baking powder, and salt. Stir in buttermilk, eggs, and vanilla until just combined.

3. Pour berries into a greased 2-quart baking dish and dollop the batter over the fruit.

4. Bake about 45 minutes until the topping is golden and the filling bubbles. Cool 15–20 minutes before serving.

Storage

Store leftover cobbler tightly covered or in an airtight container in the refrigerator for up to five days. The filling sets up well overnight, so the cobbler is often even better the next day. To reheat the whole dish, place it uncovered in a 250°F oven for 15–20 minutes until warmed through. Reheat individual portions in the microwave for 30–45 seconds. Freezing is not recommended, as the biscuit topping can become soggy and the filling watery after thawing.

Top Tip

Do not overmix the topping. Overworking gluten-free flour can make the batter dense and tough. Mix just until ingredients are combined—the batter should be thick. Dollop large spoonfuls of batter over the berries and do not press or spread; the topping will spread and rise on its own to create a rustic cobbler finish.

Yes. Use frozen berries straight from the freezer—no need to thaw. Frozen fruit may release more liquid while baking, but the arrowroot or cornstarch in the filling will help thicken the juices into a glossy sauce.

Absolutely. Blueberries, marionberries, boysenberries, mixed berries, or a combination with stone fruit like peaches all work well. Use the same total amount of fruit and follow the recipe as written.

A cobbler has a biscuit or cake-like topping that bakes soft and tender, while a crisp features a crunchy oat-and-butter crumb topping. This recipe uses a buttermilk biscuit-style topping for a soft interior and golden edges.

Yes. Make a substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of milk and letting it sit for 5 minutes. The resulting mixture works well in the topping.

The cobbler is done when the topping is golden brown and the filling bubbles around the edges. The topping should feel set to a light touch. If the topping browns too fast, tent loosely with foil and continue baking until the filling is hot and bubbly.

Yes. Bake, cool, cover, and refrigerate overnight. The filling firms and flavors deepen. Reheat the whole cobbler uncovered at 250°F for 15–20 minutes, or warm individual servings in the microwave for 30–45 seconds before serving.
