Let’s Make it Together
Prepare the Batter: Preheat your oven to 350°F (175°C) and line a cupcake pan with liners. In a large bowl, cream together softened butter and sugar until light and fluffy.
Add Wet Ingredients: Mix in eggs one at a time, followed by fresh lemon juice and zest. The batter should smell like a citrus grove on a sunny day.
Combine Dry Ingredients: In another bowl, whisk together flour, baking powder, and poppy seeds. Gradually add this mix to your wet ingredients while alternating with milk until fully combined.
Bake the Cupcakes: Fill each liner about two-thirds full with batter. Bake in your preheated oven for 18-20 minutes or until golden brown and a toothpick comes out clean.
Make the Frosting: While those heavenly cupcakes cool down, blend blackberries until smooth. Combine fruit puree with softened butter in another bowl before gradually adding powdered sugar until you achieve your desired consistency.
Frost and Serve!: Once cooled completely, use a piping bag (or simply a knife) to frost each cupcake generously with the blackberry frosting. Garnish with extra blackberries if you’re feeling fancy!
