DIRECTIONS
Make the Tangzhong
1- Whisk together milk and flour in a small saucepan until smooth.
2- Cook over medium heat, whisking constantly, until a thick paste forms (like mashed potatoes), about 2–3 minutes.
3- Scrape into a bowl and let cool completely before using (10–15 minutes).
Make the Dough & First Rise
1- In a stand mixer with a dough hook, combine flour, sugar, yeast, and salt. Add the milk, egg + yolk, and all the cooled tangzhong. Mix on low for 2–3 minutes until a shaggy dough forms.
2- Increase to medium speed and mix for 5–6 minutes until the dough is firm, elastic, and tacky.
3- Add the butter 1–2 tablespoons at a time, mixing until each addition is fully incorporated before adding the next. Scrape bowl/hook as needed. Once all butter is added, mix 7–10 minutes on medium speed until the dough is smooth, glossy, and can stretch thin without tearing (passes the windowpane test).
4- Shape the dough into a ball and place in a lightly greased medium bowl. Cover with plastic wrap.
Then, choose one of the following rise options: — Same-Day (Faster): Let dough rise at room temperature for 1½ to 2 hours, until slightly puffy. Then transfer to a plastic wrap-lined sheet tray, gently press into a rectangle, cover, and refrigerate for at least 1 hour. —
Overnight (Preferred): Let dough rest (covered) at room temperature for 1 hour to kickstart fermentation. Then transfer to a plastic-lined sheet tray, gently press into a rectangle, cover, and refrigerate overnight (8–24 hours).
Tip: Shaping into a clean rectangle here makes rolling later much easier.
Make the Chocolate Filling
1- Heat butter and cream in a saucepan over low until melted and steaming.
2- Remove from heat and add chopped chocolate, ensuring it’s fully submerged. Let sit for 2 minutes, then stir until smooth.
3- Whisk in cocoa powder, powdered sugar, salt, and vanilla until fully combined.
4- Cool at room temp until thick and spreadable like frosting.
Shape & Second Rise
1- Line and grease an 8.5 x 4.5″ loaf pan with parchment paper, leaving a bit of overhang on the long sides for easy removal after baking.
2- On a lightly floured surface, roll the chilled dough to an 11″ x 22″ rectangle (short side facing you).
3- Spread chocolate filling evenly all the way to the edges. Then, roll up tightly from the short (11″) side into a log.
4- Place log on a tray, cover, and chill for 20–30 minutes to firm up for clean slicing.
5- Trim off ends with a sharp knife, then slice log lengthwise into two equal strands.
6- With cut sides facing up, twist strands tightly together 3–4 times.
7- Gently press and compact the twisted log to fit your loaf pan snugly.
8- Transfer to the prepared pan. Cover and let rise in a warm spot for 1.5–2 hours, until puffy.
Tip: Take a before/after photo to help gauge rise.
Bake
1- Preheat oven to 350°F (175°C).
2- Bake for 50–55 minutes, placing the pan on a baking sheet. Tent with foil after 25–30 minutes to prevent over-browning. Internal temp should read 190–195°F (88–90°C).
3- While baking, make the simple syrup, cooking the sugar and water in a small saucepan until sugar has dissolved.
4- When the babka comes out of the oven, pour the syrup over it immediately while still hot — use all of it.
5- Let the loaf cool completely in the pan before removing. Serve slightly warm. Wrap tightly once cooled and keep 2–3 days at room temp, or freeze for longer storage
