Ingredients

• 2 cups (250g) all-purpose flour (spooned & leveled)
• 1 and 1/2 Tablespoons poppy seeds
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
• 1/2 cup (100g) granulated sugar
• 1/4 cup (50g) packed light or dark brown sugar
• 1/2 cup (120g) sour cream or plain yogurt, at room temperature
• 2 large eggs, at room temperature
• 1 and 1/2 Tablespoons fresh lemon zest
• 1 and 1/2 teaspoons pure vanilla extract
• 1/4 cup (60ml) milk (any kind), at room temperature
• 2 and 1/2 Tablespoons fresh lemon juice
• 1 and 1/2 cups (250g) fresh or frozen blackberries
• 1 cup (120g) confectioners’ sugar, sifted
• 1 Tablespoon (15ml) lemon juice
• 1 Tablespoon (15ml) milk (any kind)
• 2 teaspoons blackberry jam, or 3–4 fresh blackberries

Instructions

1. Step 1: Preheat the oven to 425°F (218°C). Spray a 12-count muffin pan with nonstick spray or line with cupcake liners. You may need a second pan or plan to bake in batches as this recipe makes up to 14 muffins. Set aside.
2. Step 2: In a large bowl, whisk together the flour, poppy seeds, baking soda, baking powder, and salt. Set aside.
3. Step 3: Using a handheld or stand mixer with a paddle attachment, beat the butter, granulated sugar, and brown sugar on medium-high speed until smooth and creamy, about 3 minutes.
4. Step 4: Add the sour cream, eggs, lemon zest, and vanilla extract to the butter mixture. Beat on medium speed until combined; the mixture may look curdled, which is normal.
5. Step 5: Add the dry ingredients and beat on low speed until almost combined. Then add the milk and lemon juice, beating on low speed until just combined. The batter will be thick.
6. Step 6: Gently fold the blackberries into the batter. If using extra juicy berries, take care to fold gently to avoid turning the batter purple.
7. Step 7: Spoon the batter into the muffin liners, filling each all the way to the top.
8. Step 8: Bake for 5 minutes at 425°F (218°C). Then reduce the oven temperature to 350°F (177°C) without opening the oven door and bake for another 16–18 minutes, or until a toothpick inserted into the center comes out clean. Total baking time is about 21–23 minutes.
9. Step 9: Let the muffins cool for 5 minutes in the pan, then transfer to a wire rack to cool completely.
10. Step 10: To make the icing, whisk together the sifted confectioners’ sugar, lemon juice, and milk until smooth. Stir in the blackberry jam or mashed fresh blackberries. For a thicker glaze, add 2–3 more tablespoons of confectioners’ sugar. Drizzle over warm or cooled muffins.

Tips & Variations

• For less tartness, use plain yogurt instead of sour cream in the batter.
• If using frozen blackberries, thaw and drain excess juice to prevent batter from becoming too wet.
• Substitute blueberries or raspberries for blackberries for a different berry twist.
• Add a teaspoon of lemon extract along with the zest for extra citrus flavor.
• Use mini muffin tins for bite-sized treats; adjust baking time to about 10–12 minutes total.

Storage

Store muffins in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 1 week. Reheat gently in a microwave or oven before serving. The icing may soften when refrigerated but can be refreshed with a light drizzle of jam or a dusting of confectioners’ sugar.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use frozen blackberries in this recipe?

Yes, frozen blackberries work well. Thaw them first and gently drain any excess juice to prevent the batter from becoming too watery.

What can I substitute for sour cream?

You can use plain yogurt in equal amounts as a substitute for sour cream. It will keep the muffins moist and tender with a slightly different tang.

• 1 teaspoon baking powder
• 1/2 teaspoon salt

Wet Ingredients

• 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
• 1/2 cup (100g) granulated sugar
• 1/4 cup (50g) packed light or dark brown sugar
• 1/2 cup (120g) sour cream or plain yogurt, at room temperature

• 1/4 cup (60ml) milk (any kind), at room temperature
• 2 and 1/2 Tablespoons fresh lemon juice
• 1 and 1/2 cups (250g) fresh or frozen blackberries (see Note)

Icing

• 1 cup (120g) confectioners’ sugar, sifted
• 1 Tablespoon (15ml) lemon juice
• 1 Tablespoon (15ml) milk (any kind)
• 2 teaspoons blackberry jam, or 3–4 fresh blackberries

Instructions

1. Preheat the Oven: Preheat your oven to 425°F (218°C). Prepare a 12-count muffin pan by spraying with nonstick spray or lining with cupcake liners. Because this recipe makes up to 14 muffins, you may need a second pan or plan to bake in batches. Set the pan(s) aside.
2. Combine Dry Ingredients: In a large bowl, whisk together the all-purpose flour, poppy seeds, baking soda, baking powder, and salt until evenly mixed. Set aside.
3. Cream Butter and Sugars: Using a handheld or stand mixer with a paddle attachment, beat the softened unsalted butter, granulated sugar, and brown sugar on medium-high speed until the mixture is smooth and creamy, approximately 3 minutes. This step is crucial for light muffins.
4. Add Wet Ingredients: To the creamed mixture, add the sour cream (or plain yogurt), eggs, fresh lemon zest, and pure vanilla extract. Beat on medium speed until combined, noting the mixture may look curdled—that’s normal.
5. Incorporate Dry Ingredients: Gradually add the dry ingredients to the wet mixture, beating on low speed until almost combined. Then add the milk and fresh lemon juice, mixing on low speed until just combined. The batter will be thick and rich.
6. Fold in Blackberries: Gently fold in the fresh or frozen blackberries, being careful not to overmix to preserve their shape and prevent the batter from turning purple. If blackberries are very juicy, consider tossing them in a little flour before folding them in to avoid excess moisture.
7. Fill Muffin Pan: Spoon the batter into the prepared muffin liners, filling each cup all the way to the top to achieve nicely domed muffins.
8. Bake the Muffins: Place the muffin pan in the oven and bake at 425°F (218°C) for 5 minutes. Then, without removing the muffins, reduce the oven temperature to 350°F (177°C) and continue baking for another 16–18 minutes, or until a toothpick inserted into the center comes out clean. Total baking time is about 21–23 minutes.
9. Cool the Muffins: Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
10. Prepare the Icing: In a bowl, whisk together sifted confectioners’ sugar, lemon juice, and milk until smooth. Stir in the blackberry jam or mashed fresh blackberries for a natural and vibrant flavor. If the icing is too thin, add 2–3 more tablespoons of sifted confectioners’ sugar to thicken it as desired.
11. Glaze the Muffins: Drizzle the lemon-blackberry icing over the warm or cooled muffins for an extra burst of flavor and a beautiful finish.
12. Storage: Store muffins covered at room temperature for up to a few days, or refrigerate for up to one week to maintain freshness.

Notes

• Use fresh or frozen blackberries; if they are extra juicy, toss them lightly in flour before folding into the batter to prevent the muffins from becoming too wet.
• These muffins may yield 12–14 depending on the size of your muffin cups.
• For a dairy-free option, substitute butter with a plant-based alternative and use lactose-free yogurt or sour cream.
• You can add a little sparkle to the muffins by sprinkling raw sugar on top before baking for extra crunch.
• Adjust icing thickness by varying the confectioners’ sugar to create your preferred glaze consistency.
