01 -
Heat your oven to a low 200°F (95°C). You'll switch it off soon for letting the dough rise.
02 -
Grab your stand mixer’s bowl (or your largest bowl). Toss in flour, salt, and yeast, and mix everything together.
03 -
In a heat-safe bowl, melt butter with milk and white sugar in the microwave. Give it 60-90 seconds to warm up, then stir well.
04 -
Slowly pour the warmed-up milk mix into the dry ingredients while your mixer runs with a dough hook on medium. Once it’s mixed in, add the egg. Keep going at low speed until it’s a sticky dough. Turn up to medium-low for another 2-3 minutes to make it smoother and stretchy.
05 -
Sprinkle flour into the mix a tablespoon at a time until the dough pulls away from the edges. It should be tacky but not stick to your finger when touched.
06 -
Pop some plastic wrap over the bowl, and let the dough chill for 10 minutes so it softens up a bit.
07 -
As the dough takes a break, whisk cinnamon, cornstarch, and brown sugar together in a bowl. Set it aside for later use.
08 -
Work on a floured surface and begin rolling the dough out. Halfway through, throw on half of the sprinkles, press them gently, fold the dough into thirds, and roll it flat into a big rectangle (about 12×18 inches).
09 -
Scatter the other half of the sprinkles across the top. Press them lightly so they stick well.
10 -
Slightly melt the butter and drizzle it over the dough. Spread it evenly with a brush or spatula, leaving one long edge bare. Sprinkle the cinnamon-sugar mixture over the butter.
11 -
Firmly roll the dough up along the short side toward the clean edge. Cut the log into 9 equal slices using unflavored dental floss, then place them in a greased 8×8-inch pan.
12 -
Turn the oven off completely. Cover the rolls with foil and stick the pan inside for 30 minutes to rise until they’re puffy.
13 -
Pull the pan out, take off the foil, and preheat the oven to 350°F (175°C). Let them bake for 26-32 minutes until they’re golden brown on top.
14 -
In a medium bowl, beat the butter with both extracts and salt. Mix in powdered sugar and milk until it’s smooth and creamy.
15 -
Cool rolls for 10-20 minutes after baking. Spread frosting over the top and enjoy warm with friends or family.
