Follow these steps to create your Strawberry Bridal Shower Cupcakes:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Line a cupcake pan 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 until light and fluffy.
4. Add Eggs: Beat in the eggs, one at a time, ensuring each is well incorporated before adding the next.
5. Combine Wet Ingredients: Stir in the buttermilk, vanilla extract, and strawberry puree until well mixed.
6. Add Dry Ingredients: Gradually add the dry mixture to the wet ingredients, mixing just until combined. Avoid overmixing to keep the cupcakes light.
7. Fill Cupcake Liners: Spoon the batter into the prepared cupcake liners, filling each about two-thirds full.
8. Bake: Place the pan in the preheated oven and bake for 15-20 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Remove the cupcakes from the oven and allow them to cool in the pan for 10-15 minutes. Then, transfer them to a wire rack to cool completely.
10. Prepare the Frosting: In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar and strawberry puree, mixing until smooth. Add vanilla extract and adjust the consistency with heavy cream as needed.

Once your cupcakes are cool, frost them generously with the strawberry frosting using a piping bag or a spatula.
