Start by combining semi-sweet and milk chocolate chips with cream, butter, and vanilla in a non-stick pan. Melt over low heat, stirring constantly. The mixture should be smooth and glossy in about 5 minutes.
In another pan, melt white chocolate with cream, corn syrup, butter, vanilla, and salt. Keep the heat low and stir until fully combined. You’ll see a silky, shiny fondue that’s ready for dipping.
Place the ramekins of milk and white chocolate at opposite ends of your serving board. Arrange fruits, pretzels, mini donuts, cookies, and strawberries in between. Serve immediately while the chocolate is warm and melty for the best experience.
