Ingredients

For the Dough

• 1 packet (7 g / 2 1/4 teaspoons) instant yeast
• 1/4 cup (50 g) granulated sugar
• 1/2 teaspoon (3 g) fine salt
• 1/3 cup (80 ml) whole milk, warmed to about 105°F (40°C)
• 1/3 cup (80 g) full-fat sour cream, at room temperature

• 1 teaspoon (5 ml) vanilla extract

For the Walnut Filling

• 2 cups (200 g) walnut pieces, finely ground
• 1/2 cup (120 ml) whole milk
• 1/2 cup (100 g) granulated sugar
• 2 tablespoons (40 g) honey
• 2 tablespoons (28 g) unsalted butter
• 1 teaspoon finely grated lemon zest
• 1/2 teaspoon (2.5 ml) vanilla extract

For the Egg Wash

• 1 large egg yolk
• 1 tablespoon (15 ml) whole milk

For Finishing

• Powdered sugar, for dusting (optional)

Step-by-Step Instructions

Step 1: Make the Walnut Filling

In a medium saucepan, combine the milk, sugar, honey, and butter. Heat over medium heat, stirring, until the sugar dissolves and the mixture just begins to simmer, about 3 minutes.

Remove the pan from the heat and stir in the ground walnuts, lemon zest, vanilla, and rum, if using. The filling should be thick and spreadable. If it's too stiff, stir in milk 1 teaspoon at a time. Let it cool to room temperature.

Step 2: Mix the Dough

In a small bowl, combine the warm milk with the yeast and a pinch of the sugar. Let it sit for 5 minutes, until foamy, or go straight to the next step if you're using instant yeast mixed directly into the flour.

In a large bowl, whisk the flour, remaining sugar, and salt. In another bowl, whisk the yeast mixture, sour cream, eggs, melted butter, and vanilla until smooth. Pour the wet ingredients into the flour and stir until a soft dough forms.

Step 3: Knead and First Rise

Knead the dough on a lightly floured surface for 8 to 10 minutes, until smooth, elastic, and slightly tacky. Do the windowpane test: stretch a small piece gently between your fingers. It should become thin enough to let light through without tearing.

Shape the dough into a ball, place it in a lightly oiled bowl, cover, and let it rise in a warm spot for about 1 hour, until doubled in size.

Step 4: Roll and Fill

Punch the dough down gently and roll it out on a lightly floured surface into a rectangle about 30 by 40 centimeters (12 by 16 inches) and 3 millimeters (1/8 inch) thick.

Spread the cooled walnut filling evenly over the dough, leaving a 2-centimeter (3/4-inch) border along the top edge. Starting from the long edge nearest you, roll the dough up tightly into a log. Pinch the seam firmly to seal it, and tuck the ends under.

Step 5: Second Rise

Line a baking sheet with parchment paper. Transfer the roll seam side down onto the sheet, curving it slightly into a crescent or keeping it straight. Cover loosely and let it rise for 30 to 40 minutes, until puffy.

Step 6: Egg Wash and Bake

Preheat the oven to 350°F (175°C), with a rack in the middle. Whisk the egg yolk with the milk, then brush it gently over the top of the roll.

Bake for 35 to 40 minutes, until the top is deep golden and the roll sounds hollow when tapped on the bottom. If the top browns too quickly, tent it loosely with foil.

Step 7: Cool and Slice

Let the roll cool on the baking sheet for 15 minutes, then transfer it to a wire rack to cool completely, about 1 hour. Slice with a sharp serrated knife, using a gentle sawing motion. Dust with powdered sugar just before serving, if you like.

Useful Baking Tips

• Warm the milk, don't hot-start it. Milk that's too hot can kill the yeast. It should feel warm to the touch, not hot.
• Roll the dough evenly. An even thickness bakes evenly and makes a neater spiral.
• Seal the seam well. A firm seal keeps the filling from leaking out during the second rise and the bake.

Common Mistakes to Avoid

• Filling leaking out: The filling was too loose, or the roll wasn't sealed well. Thicken the filling and pinch the seam firmly.
• Dense or heavy roll: The dough didn't rise fully, or it was too cold. Let it rise in a warm spot until doubled.
• Dry or crumbly filling: Not enough milk or butter went in while the filling was cooking. Add milk a teaspoon at a time until it's spreadable.
• Burnt bottom: The pan was too dark or set too low in the oven. Use a light-colored baking sheet on the middle rack.
• Sticky dough: The dough absorbed too much moisture. Add flour 1 tablespoon at a time during kneading, only if it's still very sticky.

Storage and Reheating

Store the roll, wrapped or in an airtight container, at room temperature for up to 3 days. For longer storage, refrigerate it for up to 1 week.

To freeze, wrap the cooled roll tightly and freeze it for up to 2 months. Thaw it at room temperature, then warm slices in a 300°F (150°C) oven for a few minutes if you'd like them warm.

Variations

• Raisin filling: Stir 1/3 cup (50 g) of plumped raisins into the cooled filling.
• Orange zest: Replace the lemon zest with finely grated orange zest for a brighter flavor.
• Chocolate drizzle: Melt 2 ounces (55 g) of dark chocolate and drizzle it over the cooled roll.

Frequently Asked Questions

Can I make the dough ahead?

Yes. After the first knead, cover the dough and refrigerate it for up to 1 day. Let it sit at room temperature for 30 minutes before rolling it out.

Why does my filling taste dry?

It may have cooked too long, or it needed more milk or butter. Stir in a spoonful of milk while the filling is still warm to loosen it.

Can I use a different nut?

Yes. Hazelnuts work well in this filling. Toast and finely grind them, then use the same amounts.

Do you add raisins or rum to your walnut roll, or keep it simple? Tell us in the comments.

Editor's note (not part of the article)

1. Video position: I placed the video after the dough is rolled, filled, and sealed into a log, before the second rise. Rolling tightly and sealing the seam is the step that decides whether the filling stays inside, so readers can see it done before they bake.
2. Blogger improvement: Add a "Make ahead" timeline near the top showing that the dough can rest in the refrigerator overnight. Readers planning a holiday baking day can then split the work over two days.
3. Metric to watch: Track comments that mention leaking filling, dry filling, or dense dough. Those comments show which step readers struggle with most, which can guide whether to add a close-up photo of the rolling or a short note on dough temperature.
