Toss sliced venison steak, corn starch, salt, and black pepper together in a large bowl or plastic bag until the meat is well coated.
Drizzle sesame oil in a large skillet set over medium high heat and add the venison. Cook until the venison is nicely seared, then remove and set aside.
In a separate large pot, cook the stir fry noodles according to the package instructions. This can be done while the meat and vegetables saute.
Add more oil if needed and then place the sliced bell peppers in the skillet. Saute until they begin to soften, then add baby corn, and minced garlic. Cook for an additional 1-2 minutes.
While the vegetables cook, add the stir fry sauce ingredients to a small bowl and whisk together.
Add the venison back into the large skillet along with all of the stir fry sauce. Stir everything to combine and simmer for two minutes, or until the sauce is thickened slightly.
Add stir fry noodles to the skillet, toss to evenly coat with sauce then serve topped with green onions and chopped peanuts.
