This easy raspberry cobbler has a jammy, lemon-kissed raspberry filling and a tender sweet biscuit topping — not a poured batter. The biscuits bake up golden and buttery while the berry filling bubbles up around the edges. Works with fresh or frozen raspberries, high altitude tested, and done in under an hour.

Instructions
Preheat oven to 375°F. Add butter to an 8x8-inch baking dish and place in oven until melted. Remove and swirl to coat the bottom.
In a medium bowl, gently stir together raspberries, brown sugar, granulated sugar, flour, vanilla extract, and lemon zest. Pour into the prepared baking dish.
In a small bowl, whisk together flour, white sugar, salt, and baking powder. Cut in cold butter until the texture of small pebbles.
Add cold buttermilk and stir until about 80% incorporated — a few streaks of flour should remain. Do not overmix.
Spoon biscuit dough in 2–4 tablespoon scoops over the filling, spacing 1–2 inches apart. Sprinkle with turbinado sugar.
Bake 35–40 minutes until biscuits are deep golden brown and raspberry juices are rapidly bubbling.
Rest 15–20 minutes before serving.
Notes
Cold butter and buttermilk — keep both extra cold for the flakiest topping.
80% mixing rule — stop when 80% of the buttermilk is incorporated. Undermixing = tender biscuits. Overmixing = tough.
Frozen raspberries — use straight from the freezer; do not thaw. Add 5–7 minutes bake time.
Buttermilk sub — 1 teaspoon vinegar or lemon juice + fill to ⅓ cup line with whole milk, rest 5 minutes.
Brown butter option — melt the butter an extra 5–7 minutes until milk solids turn golden for a richer base. Spread into a shallow dish and chill completely before cutting into the flour. Plan ahead — it needs time to firm back up.
Gluten-free — swap flour in filling and topping with a 1:1 GF blend. Let the batter rest for 5 minutes before baking and cool completely before enjoying.
Dairy-free/vegan — use vegan butter and vegan buttermilk.
High altitude (5,000+ ft) — reduce baking powder to ½ teaspoon, reduce biscuit sugar by 1 tablespoon.
Storage — refrigerate 4–5 days, freeze up to 3 months.
