Ingredients

• 2 cups all-purpose flour
• 1 Tbsp baking powder
• 1½ tsp salt
• ½ tsp cinnamon
• 3 Tbsp sugar
• 1 stick unsalted butter, very cold
• ¾ cup buttermilk, approximately
• 1 cup frozen blackberries
• ½ stick melted salted butter (for brushing)
• 1½ tsp grated lemon zest
• 1 cup powdered sugar
• ½ stick butter, melted
• zest of 1 lemon
• 1 Tbsp + 1 tsp lemon juice
• extra splash of lemon juice and sugar for sprinkling on berries

How to make Blackberry-Lemon Biscuits

Step 1: Prepare your ingredients and tools. Preheat your oven to a blazing 500°F. If you have a cast iron skillet, prepare it by wiping a very thin layer of bacon grease on the bottom. In a small bowl, gently toss the frozen blackberries with an extra splash of lemon juice and a sprinkle of sugar to enhance their flavor. Set aside.

Step 2: In a separate small bowl, whisk together the ingredients for the glaze: powdered sugar, ½ stick of melted butter, the zest of 1 lemon, and 1 Tbsp + 1 tsp of lemon juice. Stir until the powdered sugar is completely dissolved and the glaze is smooth. Set this aside as well.

Step 3: In a large mixing bowl, combine the dry ingredients. Whisk together the all-purpose flour, baking powder, salt, 3 Tbsp of sugar, cinnamon, and 1½ tsp of grated lemon zest until well blended.

Step 4: Incorporate the cold butter. Using a box grater, grate the frozen stick of unsalted butter directly into the dry ingredients. You can also cut it into small, pea-sized pieces. Use a pastry blender or your fingertips to quickly work the butter into the flour mixture until it resembles coarse crumbs.

Step 5: Add the buttermilk. Pour the buttermilk in slowly, mixing gently with a fork just until the dough begins to come together and pull away from the sides of the bowl. Be careful not to overmix!

Step 6: Turn the dough out onto a well-floured surface. Gently press it into a rectangle about half an inch thick. Drain any excess juice from your prepared blackberries and scatter them over the surface of the dough. Fold one edge of the dough over the berries to enclose them, then gently flatten the dough back out to a thickness of about 1 inch.

Step 7: Using a biscuit cutter, a sharp knife, or even the rim of a coffee mug, cut out 8 biscuits. Place them snugly together in your prepared cast iron skillet (or on a baking sheet).

Step 8: Bake for 15 to 20 minutes. About 7-8 minutes into the baking time, quickly remove the skillet from the oven and brush the tops of the biscuits generously with the melted salted butter. Return to the oven and continue baking until the tops are golden brown and the berries are bursting. Keep a close eye on them, as they can burn quickly at this high temperature.

Step 9: Once baked, remove the skillet from the oven and let it cool on a wire rack for about 10 minutes. Drizzle your prepared lemon glaze over the warm biscuits. Serve immediately and enjoy!

How to serve Blackberry-Lemon Biscuits

These biscuits are at their absolute best when served warm from the oven, with the glaze still glistening. They are a perfect centerpiece for a weekend brunch, served alongside a pot of hot coffee or tea. They are also rich and sweet enough to be served as a rustic dessert, perhaps with a small scoop of vanilla bean ice cream to complement the warm fruit. No matter how you serve them, they are sure to disappear fast!

How to store Blackberry-Lemon Biscuits

While these biscuits are best enjoyed the day they are made, you can store leftovers. Once cooled completely, place them in an airtight container. They can be stored at room temperature for up to 2 days. For longer storage, you can freeze the biscuits. Wrap them individually in plastic wrap and then place them in a freezer-safe bag. They will keep in the freezer for up to 2 months. To reheat, let them thaw at room temperature or warm them gently in a microwave or oven.

Tips to make Blackberry-Lemon Biscuits

Keep it Cold: The secret to a flaky biscuit is cold butter. The recipe note to freeze the butter is gold! Grating a frozen stick of butter is the fastest way to incorporate it into the flour without it melting from the heat of your hands.

Don’t Overwork the Dough: Mix the dough just until it comes together. Overworking develops the gluten in the flour, which will result in tough, dense biscuits instead of light and fluffy ones.

Frozen Berries are Key: Using frozen blackberries helps prevent them from turning to complete mush and staining your entire dough purple as you work with it. They will hold their shape better and create distinct pockets of fruit.

The Skillet Secret: Baking in a preheated cast-iron skillet gives the biscuits an unbeatable crispy, golden-brown bottom. The bacon grease adds a subtle, savory note that beautifully contrasts the sweet and tart flavors.

Mid-Bake Butter Brush: Don’t skip the step of brushing the biscuits with melted butter halfway through baking! This is what helps the tops get that rich, golden color and adds an extra layer of buttery flavor.

FAQs About Blackberry-Lemon Biscuits

Can I use fresh blackberries instead of frozen?

You can, but the recipe works best with frozen berries. Fresh berries are much more delicate and will likely burst and release their juices while you’re folding the dough, creating a messier, soggier result. If you only have fresh, pop them in the freezer for at least an hour before using.

Why are my biscuits dry?

Dry biscuits are usually the result of two things: adding too much flour or overbaking. When measuring flour, spoon it into your measuring cup and level it off rather than scooping directly from the bag. Also, keep a close watch on the biscuits in the oven; they’re done when they are lightly golden on top.

My biscuits didn’t rise much. What went wrong?

There are a few potential culprits. First, check the expiration date on your baking powder; old leavening agents lose their power. Second, ensure your butter and buttermilk were very cold. Cold ingredients create steam in the hot oven, which helps the biscuits puff up. Finally, be sure not to overmix the dough, which can make the biscuits tough and flat.

Final Thoughts

These Blackberry-Lemon Biscuits are a true celebration of flavor and texture. From the flaky, buttery layers to the pockets of jammy berries and the bright lemon glaze, every bite is a delight.
