Creating Lemon Blueberry Tiramisu Mini Cheesecakes can be straightforward if you follow these simple steps:

1. Prepare the Crust: In a mixing bowl, combine graham cracker crumbs and melted butter. Mix until well combined.
2. Form the Base: Press the crumb mixture firmly into the bottom of mini cheesecake cups or a muffin tin lined with paper liners. Set aside.
3. Make the Cheesecake Filling: In a large bowl, beat the softened cream cheese until smooth. Gradually add powdered sugar, mixing until well combined.
4. Add Flavor: Stir in vanilla extract, lemon zest, and lemon juice until fully incorporated.
5. Whip Cream: In another bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until combined.
6. Layer the Cheesecakes: Spoon a layer of the cheesecake filling over the crust in each cup, smoothing the top.
7. Add Blueberries: Distribute fresh blueberries evenly over the cheesecake layer.
8. Soak the Coffee: In a small bowl, combine cooled coffee and coffee liqueur (if using). Drizzle a small amount over the blueberries in each cup.
9. Repeat Layers: Add another layer of cheesecake filling on top of the blueberries, smoothing it out.
10. Chill: Cover the mini cheesecakes and refrigerate for at least 1.5 hours or until set.
11. Garnish: Before serving, garnish with additional blueberries and mint leaves if desired.

These steps will help you create these delightful mini cheesecakes, ensuring they turn out incredible every time.
