Toss together the flour, sugar, yeast, and salt in the mixing bowl for your stand mixer. Heat up the butter in the microwave, stir in the buttermilk, and warm it till it’s between 120-130°F (if using Red Star Platinum yeast). Add the melted butter mix and eggs to the bowl, then knead everything on low for 5-7 minutes to get a soft dough.

Move the dough into a bowl lightly greased with oil, cover it with plastic wrap, and stick it somewhere warm for 2 to 2½ hours to double in size. Line a 9×13 dish with foil and spray with cooking spray while you wait.

Stretch the dough to make a rectangle about 26 inches long and 13 inches wide. Coat it evenly with butter, then spread the marmalade, and finally sprinkle on the brown sugar. Starting on the long side, roll it up tightly and slice it into 20 pieces using dental floss.

Set the rolls into your prepared dish, cover again, and let them sit until they expand by about double, which usually takes an hour. Bake them at 375°F for roughly 15 minutes until they’ve got a nice golden top.

Mix the orange juice, vanilla, powdered sugar, salt, and milk together till smooth and creamy. Add in 2 teaspoons of orange zest, then pour the glaze over the warm rolls. Use the leftover zest to sprinkle on top.
