Allow pickles to drain on a triple layer of paper towels for at least 15 minutes. Press on the paper towels to blot out as much excess moisture as possible. Set aside.
Using an electric mixer, cream together the cream cheese, onion, pickle juice, sour cream, real mayonnaise, dill, pepper, salt and garlic powder on medium-low speed until thoroughly combined. Add Diplicious Dill Pickle Dip Mix, if using. Using a rubber spatula, stir in the chopped dill pickles. Serve immediately or cover and refrigerate for up to 1 day before serving. Serve with your favorite pretzels and/or crackers.
