1. Prepare the Oven and Muffin Tin: Setting the Stage for Baking

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Line Muffin Tin: Line a standard 12-cup muffin tin with paper or silicone cupcake liners.

2. Make the Graham Cracker Crust: A Buttery Base

1. Combine Ingredients: In a medium bowl, combine the graham cracker crumbs, ⅓ cup of granulated sugar, and the melted butter.
2. Mix Well: Stir the ingredients together with a fork until the crumbs are evenly moistened and the mixture resembles wet sand.
3. Press into Liners: Divide the graham cracker mixture evenly among the lined muffin cups. Use your fingers or the back of a spoon to firmly press the mixture into the bottom of each liner, forming a compact crust.

3. Pre-Bake the Crust (Optional but Recommended): Ensuring a Crispy Base

1. Bake: Place the muffin tin in the preheated oven and bake the crusts for 5 minutes.
   • Tip: Pre-baking the crust helps it to firm up and prevents it from becoming soggy when the filling is added.
2. Cool: Remove the muffin tin from the oven and set it aside to cool slightly while you prepare the cheesecake filling.

4. Make the Lemon Cheesecake Filling: Creamy, Tangy, and Smooth

1. Beat Cream Cheese: In a large mixing bowl, beat the softened cream cheese with an electric mixer (handheld or stand mixer) on medium speed until it’s smooth and creamy, about 2 minutes.
2. Add Sugar: Gradually add the 1 ¼ cups of granulated sugar to the cream cheese and continue beating until well combined and the mixture is light and fluffy.
3. Incorporate Eggs: Add the 3 large eggs one at a time, beating on low speed until just combined after each addition. Be careful not to overmix.
4. Add Lemon and Vanilla: Stir in the 3 tablespoons of lemon juice, 2 tablespoons of lemon zest, and 1 ½ teaspoons of vanilla extract until well blended. Scrape down the sides of the bowl as needed.

5. Assemble the Mini Cheesecakes: Building the Layers

1. Spoon Filling: Spoon the lemon cheesecake filling evenly into the prepared muffin cups, on top of the pre-baked (or unbaked) graham cracker crusts. Fill each liner about ¾ full.

6. Bake the Mini Cheesecakes: Achieving a Set and Creamy Texture

1. Bake: Place the muffin tin in the preheated oven.
2. Baking Time: Bake for 16-18 minutes.
   • Check for Doneness: The cheesecakes are done when the edges are set and the centers are still slightly wobbly.

7. Cool and Chill: Setting the Cheesecakes

1. Cool in Pan: Remove the muffin tin from the oven and let the mini cheesecakes cool completely in the pan at room temperature.
2. Chill: Once cooled, cover the muffin tin with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the cheesecakes to fully set.

8. Make the Lemon Glaze: A Bright and Tangy Finish

1. Combine Ingredients: While the cheesecakes are chilling, prepare the lemon glaze. In a small saucepan, whisk together 1 cup of granulated sugar, 2 large eggs, ¼ cup of lemon juice, and 3 tablespoons of lemon zest until well combined.
2. Add Butter: Add the 6 tablespoons of melted butter to the saucepan.
3. Cook and Stir: Cook over medium heat, stirring constantly, until the mixture thickens and coats the back of a spoon. This should take a few minutes.
   • Tip: The glaze will thicken as it cools.
4. Cool: Remove the saucepan from the heat and pour the glaze into a small, heat-safe bowl. Let it cool for about 15 minutes.
5. Chill: Cover the bowl with plastic wrap and place it in the refrigerator until cold, or overnight.

9. Glaze and Serve: The Final Touches

1. Remove Cheesecakes: Once the cheesecakes are thoroughly chilled, carefully remove them from the muffin tin and peel away the paper liners.
2. Glaze: Add the cooled lemon glaze to each cheesecake.
3. Serve: Serve the Mini Lemon Cheesecakes chilled and enjoy!
