Step 1: Preheat your oven to 400°F (200°C). Prick the washed sweet potatoes several times with a fork and place them on a parchment-lined baking sheet.
Step 2: Bake for 45-60 minutes, or until completely tender when pierced with a knife.
Step 3: While the potatoes are baking, prepare your desired toppings and place them in small serving bowls.
Step 4: The Kumpir Mash: Working quickly while the potatoes are piping hot, slice them lengthwise (but not all the way through).
Step 5: Gently fluff the inside flesh with a fork. Add 1 tablespoon of vegan butter, a generous pinch of salt, and 1/4 cup of vegan cheese to each potato.
Step 6: Use a fork to vigorously mash the butter and cheese into the potato flesh until it becomes a creamy, stretchy puree inside the skin.
Step 7: Top your Kumpir base with your favorite combination of ingredients from the options above, drizzle with sauce, and serve immediately!
