First Step: Soften the butter and cream cheese by leaving them at room temperature for about 30 minutes, ensuring they’re easy to mix for a creamy base. This prepares your workspace and avoids lumps in the frosting.

Second Step: In a mixer bowl, beat the 1/2 cup softened butter and 4 ounces softened cream cheese together until they’re smooth and creamy, which takes about 1-2 minutes on medium speed.

Third Step: Add the 3/4 teaspoons salt, 4 cups powdered sugar, and 1/3 cup thick caramel sauce to the bowl. Mix on low speed until the powdered sugar is mostly incorporated, helping to prevent a mess.

Fourth Step: Increase to high speed and beat for at least two minutes until the mixture is fluffy and well-blended, adjusting with milk or extra powdered sugar if needed for the right texture.

Fifth Step: Prepare your cupcake batter separately by mixing standard ingredients like flour, sugar, eggs, and baking powder in another bowl, then bake as per your favorite cupcake recipe.

Sixth Step: Once the cupcakes are cooled, spread or pipe the salted caramel cream cheese frosting on top for a finishing touch.

Final Step: Serve immediately for the best flavor, or store as needed, allowing the cupcakes to rest for a few minutes if adapting for vegan options by swapping dairy ingredients.
