Blueberry Swim Biscuits

Blueberry butter swim biscuits are the Southern baked treat that produces the most tender, buttery, golden biscuit you have ever made with almost no technique required. White Lily self-rising flour, sugar, buttermilk, and fresh blueberries stirred together into a soft dough, spooned directly into a layer of melted butter in a 9×9 baking dish where it literally swims in the butter as it bakes, scored into nine biscuits before the oven, baked until deeply golden with a crispy butter-fried bottom and a soft, fluffy interior, and drizzled while still warm with a simple powdered sugar icing. These are the biscuits that make people close their eyes when they take the first bite.

The flour is not optional as specified. White Lily Self-Rising Flour has a lower protein content than standard all-purpose flour and produces a noticeably lighter, more tender, more delicate biscuit than any other flour in this recipe. It is the flour Southern bakers have reached for since 1883 and the reason butter swim biscuits made with it taste like they were made by someone who has been baking biscuits their entire life.

Why You’ll Love This Recipe

The butter swim method does the work that technique would otherwise require. The dough swims in melted butter as it bakes, producing a crispy, golden, butter-fried bottom and tender, fluffy interior without any rolling, cutting, or laminating.

White Lily Self-Rising Flour is the ingredient that makes these taste specifically Southern and specifically exceptional. Its low protein content produces a crumb that is lighter and more tender than standard flour can achieve.

Fresh blueberries scattered through the dough burst during baking and create pockets of jammy, slightly sweet fruit throughout every biscuit.

The warm icing drizzled over immediately after baking melts slightly into the top of each biscuit and adds a sweet, creamy finish that turns these from a breakfast biscuit into something closer to a baked pastry.

Ingredients Needed to Make Blueberry Butter Swim Biscuits

Simple, Southern pantry ingredients. Here is what you need.

The Biscuits

White Lily Self-Rising Flour is the specifically recommended flour for this recipe. Granulated sugar adds sweetness that balances the tartness of the blueberries. Buttermilk adds tang, tenderness, and the acidity that reacts with the leavening in the self-rising flour for a proper rise. Fresh blueberries fold in for their jammy, slightly tart fruit pockets. A full stick of melted butter in the bottom of the pan is what the biscuits swim in and what produces the signature crispy, golden, buttery bottom.

The Icing

Powdered sugar and just enough heavy cream or milk to reach a smooth, drizzleable consistency produce a simple glaze that finishes the warm biscuits beautifully.

How to Make Blueberry Butter Swim Biscuits

One bowl, one baking dish, 40 minutes.

Step 1: Mix the Dough

Preheat the oven to 425°F. In a large bowl, whisk the White Lily self-rising flour and granulated sugar together until fully combined. Pour in the buttermilk and stir gently with a fork or spatula just until the mixture comes together into a soft, slightly shaggy dough with no dry flour streaks remaining. Stop stirring the moment it comes together. Fold in the fresh blueberries with a few gentle strokes.

Step 2: Add the Butter and Biscuit Mixture

Pour the melted butter directly into the bottom of a 9×9 baking dish, spreading it evenly. Spoon the blueberry biscuit dough into the buttered dish and use a spatula or lightly dampened fingers to gently spread it into an even layer that reaches all four corners. The dough will float slightly on top of the butter.

Step 3: Pre-Cut the Biscuits

Using a sharp knife or bench scraper, cut the dough all the way through into 9 equal biscuits before baking. This is the step that ensures the biscuits bake as defined individual portions rather than one undivided mass that is difficult to separate after baking.

Step 4: Bake

Bake at 425°F for 25 to 35 minutes until the biscuits are deeply golden brown on top, the bottoms are crispy from the butter, and a toothpick inserted in the center of a biscuit comes out clean. Check at the 25-minute mark and continue baking until the color is a deep, even golden brown.

Step 5: Make the Icing and Drizzle

While the biscuits are in the final minutes of baking, whisk powdered sugar with a small amount of heavy cream or milk, adding liquid gradually, until a smooth, pourable icing forms. Drizzle generously over the warm biscuits as soon as they come out of the oven so the icing softens slightly into the tops.

3. Pour in the buttermilk and stir gently just until the mixture comes together. Do not overmix. Fold in the fresh blueberries.
4. Pour the melted butter into the bottom of a 9×9 baking dish. Spoon the blueberry biscuit mixture directly into the melted butter and gently spread it into an even layer.
5. Pre-cut the dough into 9 biscuits before baking.
6. Bake at 425°F for 25 to 35 minutes until the biscuits are deeply golden and cooked through.

8. Drizzle the icing over the warm biscuits and serve immediately.

Notes

• White Lily Self-Rising Flour is specifically recommended and makes a meaningful difference. Its lower protein content produces a lighter, more tender biscuit than standard all-purpose or self-rising flours.
• Do not overmix. Stir just until no dry streaks remain. Overmixing develops gluten and produces tough, dense biscuits rather than soft, fluffy ones.
• Pre-cutting the dough before baking is the step that produces defined, cleanly separated biscuits rather than one large mass. Cut all the way through to the bottom of the dish.
• The butter in the bottom of the pan is not just for preventing sticking. The biscuits literally swim in it as they bake, producing the signature crispy, golden, buttery bottom that defines a butter swim biscuit.
