The sugar and the wheat flour were doing the least of the work.
Most cobbler recipes lean on a heavily sugared filling and a wheat-flour topping to get their texture and sweetness. Raspberries and blackberries are already lower in sugar than most fruit used in cobblers, so the filling here only needs a spoonful of a low-carb sweetener to taste balanced. The topping swaps wheat flour for almond and coconut flour, which tend to have less impact on blood sugar than refined flour. Xanthan gum stands in for the cornstarch that would normally thicken the berry juices as they bake. The oven behavior stays the same; what changed is what the batter and filling are built from.
Low-Carb Raspberry and Blackberry Cobbler

Ingredients
Berry Filling
- 1 cup raspberries, fresh or frozen
- 1 cup blackberries, fresh or frozen
- 1 tbsp low-carb sweetener, stevia or erythritol-based
- 1 tsp lemon juice, freshly squeezed
- 1 tsp vanilla extract, pure
- 0.25 tsp xanthan gum, for thickening
Cobbler Topping
- 0.75 cup almond flour, fine
- 2 tbsp coconut flour
- 2 tbsp low-carb sweetener, erythritol or monk fruit blend
- 1 tsp baking powder, aluminum-free
- 1 large egg, room temperature
- 3 tbsp butter, melted
- 0.5 tsp vanilla extract, pure
- 1 pinch salt
Instructions
- 1
Preheat the oven to 180°C (350°F) and lightly grease a 20cm (8-inch) baking dish.
- 2
In a mixing bowl, toss the raspberries and blackberries with the lemon juice, vanilla extract and sweetener until the berries are evenly coated.
- 3
Sprinkle the xanthan gum over the berry mixture and stir gently until it disappears into the juices.
- 4
Spread the berry mixture evenly in the prepared baking dish.
- 5
In a separate bowl, stir together the almond flour, coconut flour, sweetener, baking powder and salt.
- 6
Add the egg, melted butter and vanilla extract to the dry ingredients and stir until a soft dough forms.
- 7
Drop spoonfuls of the dough over the berries. It doesn't need to cover them completely; the topping spreads as it bakes.
- 8
Bake for 25 to 30 minutes, until the topping is golden and the filling is bubbling at the edges.
- 9
Let the cobbler cool for about 10 minutes before serving, so the filling has time to thicken.
- 10
Serve warm, with whipped cream, Greek yogurt or a scoop of low-carb vanilla ice cream if you'd like.
Nutrition per serving
Net carbs here means total carbohydrate (4g) minus fiber (2g). There are no sugar alcohols counted in this recipe's carb total, so nothing else is subtracted. Also per serving: 2g sugar, 6g saturated fat, 69mg cholesterol, 207mg sodium.
Nutrition is calculated from ingredient data and will vary with brands, sizes and exactly how much filling and topping end up in each serving. Treat it as close, not exact.
This is a simple dessert built from almond flour and fresh berries. It gives the comfort of a classic cobbler while keeping carbohydrates lower than a traditional wheat-and-sugar version, which is why it works for both low-carb and keto-style eating.
Sweetener swaps. Stevia, erythritol and monk fruit blends all work here. Sweetness varies by brand, so taste the berry mixture before it goes in the oven and adjust if needed.
Berry swaps. Frozen berries work as well as fresh and don't need thawing first. They release a little more juice as they bake, which the xanthan gum handles.
Xanthan gum. This is what thickens the berry filling in place of cornstarch. A little goes a long way, so stir it in well right away rather than letting it sit and clump.
Batch note. Leftovers keep in an airtight container in the refrigerator for up to 3 days; reheat gently in the oven so the topping doesn't turn soft. Freezing isn't recommended, since almond flour toppings tend to lose their texture once thawed.
