How to Make Lemon Poppy Seed Cupcakes

Ingredients

  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened to room temperature
  • 1 cup white sugar
  • 2 tablespoons lemon zest*
  • 2 large eggs
  • 1 teaspoon vanilla extract, room temperature
  • 2/3 cup sour cream, room temperature
  • 3 tablespoons fresh lemon juice*
  • 1 1/2 tablespoons poppy seeds
  • 1 1/2 cups blackberries (fresh or frozen)
  • 1 cup unsalted butter, softened to room temperature
  • 4 cups powdered sugar
  • 1/4 teaspoon salt
  • 1 tablespoon cream (if needed)

*Note: For best results, use the zest and juice of fresh lemons.

Directions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a cupcake pan with paper liners.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
  3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and sugar together on medium speed until light and fluffy (about 3-5 minutes).
  4. Add Lemon Zest and Eggs: Mix in the lemon zest, then add the eggs one at a time, ensuring each is fully incorporated before adding the next. Add the vanilla extract and mix until combined.
  5. Incorporate Sour Cream and Lemon Juice: Gradually mix in the sour cream and freshly squeezed lemon juice until the mixture is smooth.
  6. Combine Dry Ingredients: Slowly add the flour mixture to the wet ingredients, mixing just until combined. Be careful not to overmix!
  7. Add Poppy Seeds: Gently fold in the poppy seeds.
  8. Fill Cupcake Liners: Divide the batter evenly among the cupcake liners, filling each about 2/3 of the way full.
  9. Bake: Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. The tops should be golden brown.
  10. Cooling Time: Allow the cupcakes to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
  11. Make Blackberry Frosting: While the cupcakes are cooling, prepare the blackberry frosting. Blend the blackberries in a food processor until smooth, then strain if desired to remove seeds. In a large bowl, beat the softened butter until creamy. Gradually add powdered sugar, salt, blackberry puree, and cream as needed, beating until fluffy and well blended.
  12. Frost and Serve: Once the cupcakes are completely cooled, frost them generously with the blackberry frosting.

How to Store Lemon Poppy Seed Cupcakes

Store any leftover cupcakes in an airtight container in the refrigerator, where they can stay fresh for up to 3 days. To freeze cupcakes, wrap them individually in plastic wrap, then place them in a zip-top freezer bag for up to 2 months. When you’re ready to enjoy, simply thaw them in the refrigerator overnight, and the frosting can be refreshed with a quick whip. Check for any signs of spoilage before consuming and always ensure the cupcakes are cool before storing to prevent moisture build-up.

Tips to Make Lemon Poppy Seed Cupcakes

  1. Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for better emulsification.
  2. Zest Wisely: Use a microplane to get fine lemon zest without the bitter white pith.
  3. Don’t Overmix: Gently combine wet and dry ingredients to maintain a light texture.
  4. Test for Freshness: Before baking, check if your baking powder and soda are fresh for optimal rise.
  5. Optimize Flavor: Add a drizzle of lemon glaze over the frosting for an extra citrus punch.
  6. Batch Cooking: Make a double batch and freeze half un-frosted for future treats.
  7. Frosting Variation: Add a splash of vanilla extract to the frosting for deeper flavor complexity.
  8. Texture Control: If your cupcakes are too dense, consider folding in some whipped egg whites for airiness.
  9. Equipment Swap: If you lack cupcake liners, greasing your pan well or using parchment paper works too.
  10. Leftover Transformation: Repurpose leftover cupcakes into a delicious trifle with layers of fresh berries and whipped cream.

Variations

  1. Vegan Citrus Burst: Substitute butter for vegan butter and use flax eggs for a plant-based delight! The same zingy flavors will keep the cupcake experience intact without the eggs or dairy.
  2. Protein-Packed Power Cupcakes: Add in some Greek yogurt to the cupcake batter for a health boost. This addition will make the cupcakes super moist while increasing the protein content.
  3. Gluten-Free Zest: Swap all-purpose flour for almond flour or a gluten-free flour blend. You’ll still enjoy that delightful lemon flavor with a subtle nutty taste!
  4. Spiced Citrus Delight: Blend in a pinch of cardamom or ginger to elevate the flavor profile, adding a warm spice kick that pairs beautifully with the tangy lemon.
  5. Tropical Lemon Bliss: Mix in shredded coconut to give a tropical twist. Play around with the frosting by adding coconut cream to make it extra creamy and decadent!

FAQs

Can I make this ahead of time?

Absolutely! You can prepare the cupcake batter a day in advance and store it in the refrigerator. Just allow it to come to room temperature before baking. The cupcakes can also be baked a day prior and frosted just before serving for best results.

How do I store leftovers?

Keep any unfrosted cupcakes in an airtight container at room temperature for up to two days. If frosted, place them in a refrigerator to maintain freshness for approximately three days.

Can I freeze this dish?

Yes! Freeze the cupcakes unfrosted for up to two months. Wrap each cupcake in plastic wrap and place them in a sturdy container or bag. Let them thaw in the fridge overnight before frosting.

What can I substitute for lemon juice?

If you don’t have lemon juice on hand, lime juice can be a great substitute. Keep in mind that it will alter the flavor slightly but will still be delicious!

How do I prevent sticking?

Ensure that you’re using non-stick cupcake liners, or thoroughly grease and flour your cupcake pan, as it helps in easily releasing the cupcakes after baking.

Is this gluten-free?

This recipe as it stands is not gluten-free. However, substituting gluten-free flour can easily adapt the recipe for those avoiding gluten.

Can I use frozen blackberries?

Certainly! Just be aware that frozen blackberries may release more moisture, so you might need to adjust your frosting consistency with more powdered sugar.

How do I know when it’s done?

Your cupcakes are ready when they spring back lightly when touched and a toothpick inserted in the center comes out clean or with a few moist crumbs.

Can I double/halve this recipe?

Yes, you can double or halve the recipe as needed. Just ensure that if you’re changing the quantity, you maintain the same ratios for perfect results.
