1-First Step: Gather and Prep Ingredients Line a 12-cup muffin tin with paper liners. Crush graham crackers if not pre-crumbed. Zest and juice lemons ahead. Rinse blueberries and pat dry. Soften cream cheeses and butters at room temperature for 30 minutes. This mise en place keeps things smooth.

2-Second Step: Make the Crust Mix 1 1/2 cups graham cracker crumbs with 1/3 cup melted butter in a bowl. Stir until crumbs look like wet sand. Divide evenly among liners, about 2 tablespoons each. Press firmly with a spoon or glass bottom. Chill crusts in the fridge for 15 minutes to set.

3-Third Step: Prepare the Filling Beat 16 oz softened cream cheese with 1 cup powdered sugar using a hand mixer until smooth, about 2 minutes. Add zest of 2 lemons and 1/4 cup lemon juice. Mix well. In a separate bowl, whip 1 cup heavy cream to stiff peaks, 3-4 minutes. Gently fold whipped cream into cream cheese mixture. Fold in 1 1/2 cups blueberries carefully to avoid smashing them. The filling stays light and moist this way.

4-Fourth Step: Assemble the Cupcakes Spoon filling over chilled crusts, filling each liner almost to the top. Smooth tops with a spatula. Cover tin loosely with plastic wrap. Refrigerate for at least 3 hours, or overnight for best texture. The chill time firms up the moist centers perfectly.

5-Fifth Step: Whip Up the Tangy Frosting Beat 8 oz softened cream cheese and 1/4 cup softened butter until creamy. Gradually add 2 cups powdered sugar, beating on low then high. Mix in zest of 1 lemon and 2 tbsp lemon juice. Whip until fluffy, 2-3 minutes. Transfer to a piping bag fitted with a star tip.

6-Final Step: Frost and Serve Pipe frosting in swirls on chilled cupcakes. Garnish with extra blueberries and lemon zest. Serve immediately or store as noted below. Enjoy the moist lemon blueberry cupcakes with their perfect tangy balance.
