In a mixing bowl, blend the softened cream cheese and brown sugar using an electric mixer until smooth and creamy. This should only take about 30 seconds.
Pour in the vanilla extract and caramel syrup, then mix again on low speed until everything is well combined and silky.
Gently fold in the Cool Whip until the dip is fluffy and fully incorporated.
Cover and chill the dip in the fridge for at least 30 minutes, or keep it cold until you're ready to assemble the board.
While the dip chills, slice your apples. To help keep them from browning, soak the slices in a bowl with 1 tablespoon of lemon juice and 1 cup of cold water for about 5 minutes, then drain and pat dry.
Place pretzels in a Ziploc bag and crush them with a rolling pin. Just roll back and forth like you’re rolling out dough until you have small crunchy pieces.
Fill small bowls with the crushed pretzels, sprinkles, chopped nuts, and mini chocolate chips. Arrange them on a large board or platter.
Spoon the dip into a bowl and place it in the center of your board. Fill in the open spaces with apple slices, and feel free to add extras like graham crackers or pretzels for dipping.
Complete the board with a small dish of caramel syrup for drizzling! Then let everyone dig in and customize their perfect bite.
