Poppy Seeds: These tiny seeds add a delightful crunch and visual appeal to your cupcakes.
Fresh Lemons: Use freshly squeezed lemon juice for maximum brightness and flavor in every bite.
Eggs: They provide moisture and bind everything together perfectly.
Unsalted Butter: Softened butter adds richness and helps create that tender crumb.
Blackberries: Fresh or frozen blackberries can be used for making the delicious frosting.
Heavy Cream: Cream will give your frosting its luscious texture; mix it well for fluffiness!
Powdered Sugar: Essential for sweetening up your frosting without grittiness.

Let’s Make it Together
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures even baking once you put those lovely cupcakes in.
Mix Dry Ingredients Together: In a bowl, whisk together the flour, sugar, baking powder, poppy seeds, and a pinch of salt until evenly combined—this is where the magic begins.
Cream Butter and Sugar Together: In another bowl, beat softened butter with sugar until light and fluffy. You want it creamy enough to make you feel like royalty!
Add Eggs and Lemon Juice : Incorporate eggs one at a time into the butter mixture, mixing well after each addition. Then add fresh lemon juice; it should smell heavenly right about now.
Combine Wet and Dry Ingredients : Gradually add dry ingredients into wet ones while mixing gently until just combined—don’t overmix; we want airy cupcakes!
Bake Those Cupcakes!: Spoon batter into lined cupcake tins about two-thirds full. Bake for 18-20 minutes or until they’re golden brown and a toothpick comes out clean—just don’t eat them yet!
Prepare Blackberry Frosting : In a bowl, beat heavy cream until soft peaks form. Gradually add powdered sugar while mixing; fold in crushed blackberries gently for color and flavor—it’s going to be glorious.
Now all that’s left is decorating those fluffy beauties with your luscious blackberry frosting!
And voila! You’ve created lemon poppy seed cupcakes with blackberry frosting that will have everyone clamoring for seconds (and maybe even thirds). Enjoy them fresh out of the oven or let them chill in the fridge before serving—they’re delicious either way!
