Preheat oven to 400 degrees. Peel, devein and wash the shrimp. Pat shrimp dry with paper towels. Put shrimp into a large glass baking dish, add 4 TBS butter and bake for 15-20 minutes, until shrimp are cooked through. Once cooked through, set aside. Meanwhile continue to next steps.
Cook the rice noodles according to package instructions. Some tricks I learned to attain perfect rice noodles is adding 1 TBS of olive oil to the pot of boiled water when cooking rice noodles to keep the noodles from sticking together. I also stir the noodles constantly to prevent sticking. Set cooked noodles aside.
Mix the sauce ingredients together in a small bowl and set aside.
In a wok or large skillet, heat 1 TBS olive oil on medium heat. Add in 1 finely chopped Thai chili pepper (less or more depending how spicy you prefer), add in 3 minced garlic cloves. Stir until fragrant.
Add in the cooked shrimp (butter/water drained). Add 4 tsp fish sauce. Cook a few minutes, until the shrimp crisps up to your preference, 5-10 minutes.
Add in the cooked rice noodles. Pour the sauce over the noodles and shrimp. Mix well. Turn the heat down to low. Cook until rice noodles are hot and have absorbed the sauce, about 10 minutes.
Lastly, add canned baby corn (drained) and/or any other veggies you want to add. Cook an additional few minutes until veggies are cooked through.
