Heat a non-stick skillet over low heat and add the unsweetened coconut flakes. Stir frequently until lightly browned (about 1 minute). Remove and set aside.
Lightly season elk cubes with salt. Heat olive oil in a large pot over medium heat. Add the elk and brown on all sides, working in batches if needed. Remove and set aside.
Melt butter in the same pot. Add onions, bell pepper, and garlic, and sauté until softened (about 10 minutes).
Stir in yellow curry powder, cumin, sugar, and salt. Add water and coconut milk, and bring to a boil.
Return the elk to the pot and add sweet potatoes. Reduce heat to low, cover, and simmer, stirring occasionally, for 1–2 hours or until the elk is fork-tender.
Spoon the curry over steamed rice, then top with toasted coconut flakes and fresh basil. Enjoy!
