Blueberry & black tea sweet rolls made with soft tangzhong dough, filled with wild blueberries and finished with an Earl Grey cream glaze. Each spiral carries a deep ribbon of fruit through its center, the glaze melting softly into the layers, the tea lingering gently through the cream.
Baker’s Notes
Tangzhong
A small portion of flour and milk is cooked into a paste before mixing the dough. It gives the rolls their especially soft crumb and keeps them tender well into the next day.
Blueberries
Fresh or frozen blueberries both work beautifully here. I especially love the wild blueberries from Northwest Wild Foods.
Black tea
An Earl Grey you love is perfect here. I’ve been using Art of Tea’s Earl Grey Crème, rich with bergamot and a touch of French vanilla — so lovely with the blueberries.
Rolling & slicing
The dough is soft and supple. A brief rest in the refrigerator once filled makes slicing easier and keeps the spirals defined.
Baking
These rolls should stay pale, with only light color at the edges. If the tops begin to deepen too quickly, tent loosely with foil and continue baking.
Glazing
Let the rolls rest 8–12 minutes before spooning over the glaze. It will melt naturally into the warm folds and settle into the spirals.
Serving
Best enjoyed slightly warm, when the crumb pulls apart easily and the blueberries feel full within the layers, though they remain tender the following day.
Blueberry & Black Tea Sweet Rolls
Ingredients
Dreamy Tangzhong Sweet Roll Dough
Tangzhong
3 tablespoons (25 g) all-purpose flour
½ cup (120 g) whole milk
Dough
2¾ cups (330 g) all-purpose flour (I love Hayden Flour Mills Sonora)
¼ cup (50 g) granulated sugar
1 teaspoon salt
2¼ teaspoons (7 g) instant yeast
½ cup (120 g) whole milk, lukewarm
1 large egg + 1 egg yolk, room temperature
6 tablespoons (84 g) unsalted butter, very soft
Blueberry–Vanilla Bean Filling
2½ cups (350 g) blueberries (fresh or frozen)
⅓ cup (65 g) granulated sugar
1½ tablespoons cornstarch or tapioca starch
Seeds from ½ vanilla bean
Pinch of salt
½–1 teaspoon lemon juice
Black Tea Cream Glaze
½ cup (120 g) heavy cream
2 Earl Grey tea bags
1¼ cups (150 g) powdered sugar
Pinch of salt
Instructions
Dreamy Tangzhong Sweet Roll Dough
- In a small saucepan, whisk the flour and milk until smooth. Cook over medium heat, stirring constantly, until it thickens into a soft paste, about 1 minute. Remove from the heat and let cool until just warm.
- In the bowl of a stand mixer fitted with the dough hook, combine the flour, sugar, salt, and yeast.
- Add the lukewarm milk, egg, egg yolk, and the cooled tangzhong. Mix on low speed until a shaggy dough forms, then continue mixing for 1–2 minutes to bring it together.
- With the mixer on medium-low, add the butter 1 tablespoon at a time, letting each piece fully incorporate before adding the next. This should take about 4 minutes total.
- Continue mixing for 6–8 minutes more, until the dough is smooth, elastic, and slightly tacky. It should pull away from the bowl but feel very soft.
- Place the dough in a lightly oiled bowl, cover, and let rest at room temperature for 30 minutes, then refrigerate overnight (8–24 hours).
For same-day baking, let rise at room temperature for 1–1½ hours, until puffy and nearly doubled.
Blueberry–Vanilla Bean Filling
- Combine the blueberries, sugar, vanilla seeds, salt, and lemon juice in a saucepan.
- Cook over medium heat, stirring gently, until the berries burst and release their juices, 5–7 minutes.
- Stir the cornstarch with 1 tablespoon water, then add it to the pan.
- Cook another 1–2 minutes, stirring constantly, until thickened into a soft, spoonable jam — glossy and deeply blueberry.
- Transfer to a container, cover, and refrigerate until fully cooled.
Black Tea Cream Glaze
- Warm the cream until just steaming. Remove from the heat.
- Add the tea bags, cover, and steep for 8–10 minutes, until fragrant but not overpowering.
- Remove the tea bags and let the cream cool until just warm.
- Whisk in the powdered sugar and salt until smooth and pourable. The glaze should ribbon slowly from a spoon.
Assemble & Bake
- Turn the chilled dough onto a lightly floured surface and roll into a rectangle, about 12 × 16 inches.
- Spread the chilled blueberry filling evenly over the dough, leaving a ½-inch border along the long edge.
- Roll up gently but snugly into a log. Transfer to the refrigerator and chill for 20 minutes to firm slightly.
- Slice into even rolls and arrange in a parchment-lined baking dish.
- Cover tightly and refrigerate overnight. For same-day baking, let the rolls rise at room temperature instead.
- When ready to bake, let the rolls rise at room temperature until puffy and airy, about 45–75 minutes.
- Preheat the oven to 350°F (175°C).
- Bake for 28–32 minutes, until lightly golden at the edges and fully set through the center.
- Spoon the black tea cream glaze generously over the warm rolls, letting it pool and settle into the spirals.
