Add the yeast to the warm water and stir to dissolve.
Allow the mixture to rest for 5 minutes, at which point you should see bubbles on the surface.
Add flour, sugar, and salt into bowl of a stand mixer.
Stir to combine.
Add the butter to the yeast and water mixture.
Fit the mixer with the dough hook attachment. Turn the mixer on low, slowly adding the yeast and butter mixture. Increase the speed to medium and continue to mix for 3-5 minutes, or until a bowl of dough is formed.
Turn out the dough onto a countertop and knead by hand for 8-10 minutes incorporating the remaining flour. The dough will take up ½ to 1 cup of flour. You’ll know when the dough has been kneaded enough when it passes the windowpane test, meaning the dough can be stretched thin enough that light passes through it. The dough should no longer be sticky and the surface should be smooth.
Cover the dough with a dampened towel and let it rest for 10 minutes.
Make the Filling
Cut the dough into 12 equal pieces. (Use a kitchen scale if you want to be precise.)
Take a 1 oz. block of cheese and gently squeeze it into a ball.
Make the Zombies
Press and flatten a dough ball out and place a ball of cheese in the middle.
Pull up the edges of the dough around the cheese and pinch the dough into a parcel. Make sure to pinch the edges well to seal in the cheese.
Place the filled dough ball seam-side down. Using cupped hands, shape the roll into a tight sphere.
Place cheese-filled dough balls onto a parchment-lined baking sheet.
Cover lightly with plastic wrap. Let the rolls rest in a warm spot for 1-1 ½ hours, or until they have doubled in size.
Before the rolls have finished resting, preheat your oven to 375˚F.
