Creating Raspberry Lemon Heaven Cupcakes can be a delightful experience when you follow these simple steps:

1. Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Line a cupcake tin with paper liners.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar together until light and fluffy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Incorporate Buttermilk and Zest: Mix in the buttermilk, lemon zest, and lemon juice until combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
7. Fold in Raspberries: Gently fold in the fresh raspberries, ensuring they are evenly distributed throughout the batter.
8. Fill Cupcake Liners: Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.
9. Bake: Place in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and allow the cupcakes to cool in the pan for 5 minutes. Then, transfer them to a wire rack to cool completely.
11. Prepare the Frosting: In a medium bowl, beat the cream cheese until smooth. Gradually add the powdered sugar, vanilla extract, and lemon juice, mixing until creamy.
12. Frost the Cupcakes: Once the cupcakes are completely cool, frost them generously with the cream cheese frosting.
13. Garnish: Top each cupcake with a fresh raspberry for an elegant touch.

These steps will guide you in creating these incredible cupcakes effortlessly.
