Prepare the liquid (8 am) - Heat the milk with brown sugar in a small saucepan over medium heat, stirring constantly, until the milk is simmering and the sugar has fully dissolved. Turn off the heat, add the sliced butter to the hot milk mixture, and stir until completely melted. Add to a stand mixer bowl and stir in the apple butter. Let it cool.
130 grams milk, 30 grams brown sugar, 55 grams unsalted butter, 100 grams apple butter
“Autolyse” (8:15 am) - Make sure your liquid mixture is between 80 - 90°F (27 - 32°C), add flour and salt to the cooled liquid mixture. Use a spatula to mix until all the liquid is absorbed. Cover and let rest for 15 - 20 minutes.
280 grams flour, 6 grams kosher salt
Knead the dough (8:35 am) - Add all of the apple butter starter to the “autolysed” dough. Knead with the dough hook on speed 2 for 20 minutes.

Continue bulk fermentation (9 am) - Oil your hands, a bowl scraper, and your clean countertop. You can use gloves and the silicone mat on your surface to further help prevent sticking. Scrape the dough out and shape it into a ball on the oiled surface. Lightly oil the mixing bowl, then return the dough to the bowl. Cover and place in a warm spot. You will perform 2 - 3 sets of stretch and fold at 45-minute intervals. Set a timer for 45 minutes.
Neutral oil for dough handling
Stretch and fold #1 (9:45 am) - With oiled hands, lift the dough from the center. It will stretch as you lift it up and out of the bowl. If it’s sticky, use your bowl scraper to help release it. Stretch the dough into a long strip and fold in thirds like you’re folding a letter. Turn it 90 degrees, stretch it out into a long strip again and fold in thirds. Place it seam-side down back into the mixing bowl, cover, and set the timer for another 45 minutes.
Stretch and fold #2 (10:30 am) - Repeat the same process. At minimum, complete 2 sets if short on time.
Stretch and fold #3 (11:15 am) - Repeat one final set. The dough should feel stronger and more elastic. It should also have risen a bit. Cover and let it finish bulk fermentation at room temp for another 2 - 3 hours.
Divide (2:00 pm) - Using your bowl scraper, scrape the dough onto a lightly floured surface and divide into 3 portions. Roll each into a smooth ball. Cover and let rest for about 10-15 minutes.
Shape (2:15 pm) - Take each dough ball, smooth side down, flatten with your hand or roll into a rectangle, fold into thirds like a letter. Flatten again and allow it to stretch lengthwise, but keep the width slightly narrower than your loaf pan. Roll up into a log and place into the loaf pan. At this point, you can continue proofing the dough and baking immediately (see the timeline in my post) or cover the pan and refrigerate the dough.
Proof (11:00 pm) - Take the dough out of the fridge and proof overnight for 7 - 8 hours. I typically use a 15-quart storage bin as my proofing box. The dough is ready when it is very puffy, has risen well above the rim of the loaf pan, and a gentle press leaves an indentation that slowly springs back (but not immediately).
