In a large mixing bowl, combine warm water, sugar, oil, and yeast. Let sit for 15 minutes until frothy.
2. Add Remaining Ingredients
Mix in salt, eggs, and flour. Knead the dough using a dough hook or by hand for 10 minutes. Allow the dough to rest for 10 minutes.
3. Shape the Rolls
Grease a cookie sheet. Divide the dough in half and roll each half into a rectangle.
Spread ¼ cup melted butter over each rectangle and sprinkle evenly with the cinnamon-sugar mixture.
Roll the dough tightly into a log and slice into 12 rolls per half.
4. Let Rise and Bake
Place rolls on the greased cookie sheet. Allow them to rise until doubled in size.
Preheat the oven to 400°F (200°C). Bake for 12–15 minutes, or until golden brown.
5. Frosting
While the rolls bake, cream together butter, salt, vanilla, and powdered sugar. Add milk gradually until desired consistency is reached.
Frost the rolls generously while they’re still warm.
Serving and Storage Tips
Serve Fresh: Best enjoyed warm from the oven.
Storage: Store in an airtight container for up to 2 days. For longer storage, freeze the baked rolls (unfrosted) and thaw before frosting and reheating.
