Preheat Oven to 400 degrees, and spray a large baking sheet with oil.
Place a teaspoon of cream cheese in the middle of the wonton wrapper, dip your finger in water and run it across the edges of the wrapper. Then fold the wrapper over to meet in a triangle. Seal the edges and press out any air pockets.
Lay the folded wonton flat on a greased baking sheet and when they are all folded, spray the tops with oil and place in the preheated oven for 10 minutes and flipping them over after 5 minutes.
Serve immediately with Thai sweet chili sauce.
Keep the wonton wrappers in the bag and only remove one at a time so they don't dry out. If you need to make them ahead of time, remove them from the oven once done and lower the temperature to 200 degrees. Once the oven has cooled place them back in to keep warm. I only recommend this for about 30 minutes.
