Follow these easy steps to create your White Chocolate Strawberry Cupcakes:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
2. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy.
3. Add Eggs: Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next.
4. Incorporate Vanilla: Stir in the vanilla extract to add depth to the flavor.
5. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt.
6. Mix Wet and Dry Ingredients: Gradually add the dry mixture to the wet ingredients, alternating with the milk, and mix just until the batter is smooth.
7. Add White Chocolate Chips: Gently fold in the white chocolate chips and diced strawberries.
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 18-20 minutes or until a toothpick inserted into the center comes out clean.
10. Cool: Remove from the oven and allow cupcakes to cool in the tin for about 10 minutes. Then, transfer to wire racks to cool completely.
11. Make Frosting: Whip the heavy cream until soft peaks form. Gradually add the melted white chocolate, mixing until combined and smooth.
12. Frost Cupcakes: Once the cupcakes are completely cool, generously frost them with the white chocolate mixture.
13. Garnish: Top each cupcake with a slice of fresh strawberry for decoration.
