How to Make Lemon Poppy Seed Cupcakes with Blackberry Frosting Recipe
Step 1: Prepare the Cupcake Batter
Start by preheating your oven to 350 degrees Fahrenheit and line two muffin pans with cupcake liners to make cleanup a breeze. In a large bowl, sift together the flour, baking powder, baking soda, and salt; whisk these dry ingredients to ensure an even blend. In a separate bowl, beat the softened butter, sugar, and lemon zest until the mixture is light and fluffy, as this incorporates air for that beautiful cupcake rise.
Step 2: Incorporate Wet Ingredients
Add the eggs one at a time to the butter mixture, beating well after each addition, then mix in the vanilla extract. Next, using your mixer on low speed, alternate adding half the sour cream then half the flour mixture, carefully folding the batter after each addition to keep it light and airy. Repeat this until all the sour cream and flour are fully combined, and gently fold in the freshly squeezed lemon juice and poppy seeds to spread those bright, crunchy delights evenly throughout the batter.
Step 3: Bake to Perfection
Spoon the batter into the lined muffin tins, filling each about two-thirds full to allow for rising without spilling over. Bake one tray at a time for 16 to 20 minutes on the middle rack, or until the cupcakes’ tops are set and a toothpick inserted in the center comes out clean. Let them cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Step 4: Create the Blackberry Frosting
To make the signature frosting, blend your blackberries until smooth, then press the puree through a fine sieve to remove all the seeds for a silky finish. Simmer the strained puree on low heat for 10 to 20 minutes to thicken it into a luscious jam-like consistency, then let it cool completely. Beat the softened butter until fluffy, gradually add powdered sugar and salt, then blend in the blackberry jam, alternating with the remaining powdered sugar to reach that perfect frosting thickness. Adjust with a splash of cream if needed for smooth piping.
Step 5: Frost Your Cupcakes
Once the cupcakes are cool, pipe or spread the blackberry frosting generously on top, making sure each cupcake gets its perfect share of that gorgeous, fruity spread. The contrast between the tangy lemon poppy base and the rich blackberry frosting is absolutely heavenly.

- 1 tablespoon cream (if needed)
Instructions
- Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C) and line two muffin pans with cupcake liners. You will make about 14 cupcakes in total.
- Combine Dry Ingredients: In a large bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. Whisk them together to distribute evenly.
- Cream Butter, Sugar, and Lemon Zest: In a separate large bowl, beat the softened butter, white sugar, and lemon zest until the mixture becomes light and fluffy, which should take a few minutes.
- Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract, mixing well after each addition to ensure a smooth batter.
- Incorporate Sour Cream and Flour Mixture: With your mixer on low speed, add half of the sour cream, then half of the flour mixture. Stop and scrape down the sides of the bowl to incorporate all ingredients evenly.
- Repeat Mixing: Repeat the process with the remaining sour cream and flour mixture, mixing gently until just combined to maintain a tender crumb.
- Fold in Lemon Juice and Poppy Seeds: Gently fold in the freshly squeezed lemon juice and poppy seeds by hand, ensuring the batter remains light and fluffy.
- Fill Cupcake Liners: Spoon the batter evenly into the prepared muffin pans, filling each liner about two-thirds full to allow room for rising.
- Bake the Cupcakes: Place one tray on the middle rack of the oven and bake for 16-20 minutes, or until the tops are set and a toothpick inserted into the center comes out clean. Let cupcakes cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

- Frost Cupcakes: Transfer the frosting into a piping bag fitted with a 1M tip or use a knife to frost the cooled cupcakes as desired.
Notes
