Grab those Twinkies and carefully slide a paper straw into each one, about halfway up.Pro Tip: If the Twinkies are super soft and you’re worried about them squishing, pop them into the fridge for 10–15 minutes beforehand. It’ll firm them up just enough to make handling a breeze. Next, pour the white chocolate chips into a small saucepan. Lightly mist them with cooking spray and melt them over medium heat. Important: Stir the chocolate constantly so it melts nice and smooth without scorching. White chocolate can be a little high-maintenance, but if you keep an eye on it, it’ll stay glossy and gorgeous.Shortcut option: You can totally melt the chips in a microwave-safe bowl, heating in 20-second bursts and stirring each time until smooth. Dip each Twinkie into the melted white chocolate, twirling it around a bit so it's nicely coated. If the chocolate starts to thicken up while you’re working, just give it another quick stir or pop it back on the heat for a few seconds.
Before the chocolate sets, go ahead and hit those Twinkies with all the patriotic sprinkles your heart desires.
Once all your Twinkies are dipped and sprinkled, set them on a baking sheet lined with parchment paper or wax paper. Let them sit at room temperature until the chocolate hardens up. If you're in a hurry, you can pop them into the fridge for about 10 minutes to speed things along.
