Essential Ingredients
Here’s what you’ll need to make this delicious dish:
-
All-Purpose Flour: Use this staple for a light and airy cupcake texture; it’s the backbone of your batter.
-
Poppy Seeds: These little guys add a subtle crunch and nutty flavor; always use fresh ones for the best taste.
-
Granulated Sugar: Sweeten the deal! This balances the tartness of lemon beautifully.
-
Baking Powder: Make sure it’s fresh to help your cupcakes rise perfectly.
-
Salt: Just a pinch enhances all those lovely flavors.
-
Unsalted Butter: Use room temperature butter for an ultra-smooth batter; it makes all the difference.
-
Lemon Zest and Juice: Fresh is key here; it infuses incredible brightness into your cupcakes.
-
Eggs: Bring these to room temperature to mix in seamlessly for better volume.
-
Milk: Whole milk gives richness; almond milk works too if you prefer dairy-free options!
-
Blackberries: Fresh blackberries create a luscious frosting; frozen will work but may change texture slightly.

Let’s Make it Together
Preheat the Oven and Prepare Your Muffin Tin: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it well to prevent sticking.
Mix Dry Ingredients: In a bowl, whisk together flour, baking powder, poppy seeds, and salt until well combined. This ensures even distribution of flavors.
Cream Butter and Sugar: In another bowl, cream together softened butter and granulated sugar until pale and fluffy. You want this mixture to look like clouds!
Add Eggs and Lemon: Beat in eggs one at a time along with lemon zest and juice. The batter should smell heavenly—like you’re walking through a citrus grove.
Combine Wet and Dry Mixtures: Gradually add your dry ingredients into the wet mixture while alternating with milk until just combined. Don’t overmix—think gentle folding rather than aggressive stirring.
Bake! Fill each muffin cup about two-thirds full with batter. Bake for 18-20 minutes or until golden brown and a toothpick inserted comes out clean.
Create Blackberry Frosting: While the cupcakes cool, blend blackberries until smooth. Mix with softened butter and powdered sugar until creamy. Adjust sweetness as desired—taste as you go!
Once cooled completely, frost those luscious cupcakes generously with blackberry frosting.
And there you have it! Your Lemon Poppy Seed Cupcakes with Blackberry Frosting are ready to dazzle at any occasion or simply brighten your day!
