In the bowl of a stand mixer, whisk warm milk, warm water, sugar, and yeast. Let it stand for 5 minutes until slightly foamy. Instant yeast can go straight in with no wait, but this short rest improves dispersion.

Add eggs, vanilla, and salt. Fit the dough hook, add 2 3/4 cups of flour, and mix on low until a shaggy dough forms, 1 to 2 minutes.

Tip: If using active dry yeast, make sure the liquid stays near 105 to 110 F. Hotter liquid can weaken yeast.

With the mixer on medium-low, add the remaining flour a few tablespoons at a time until the dough clears the sides but still clings to the bottom. Add the soft butter in 3 additions, mixing until smooth between each.

Knead 6 to 8 minutes. You are aiming for moderate gluten development. The dough should be smooth and slightly tacky.

Check: Windowpane test should stretch thin without tearing. That signals good structure for lofty berry cinnamon rolls.

Shape into a ball and place in a lightly oiled bowl. Cover and let rise in a warm spot until doubled, 45 to 60 minutes. A clear, lidded container makes it easy to monitor growth.

Speed tip: A warm oven with the light on, no heat, keeps a steady environment near 80 F.

In a small saucepan, combine berries, sugar, lemon juice, cinnamon, salt, and cornstarch. Cook over medium heat, stirring, until the mixture bubbles and thickens, 3 to 5 minutes.

Transfer to a plate to cool quickly. A cool filling is key to clean spirals and less seepage.

Flavor note: A touch of cardamom in the dough plays nicely with blueberries and raspberries.

Turn the dough onto a floured surface. Roll into a 12 by 16 inch rectangle, short side facing you, about 1/4 inch thick.

Spread 2 tbsp soft butter over the surface. Sprinkle evenly with brown sugar and cinnamon.

Dollop the cooled berry filling, then spread gently to the edges. Keep a 1/2 inch border on the far long edge.

Pro move: Use an offset spatula, moving gently to avoid tearing the dough.

Roll up from the long edge closest to you, keeping it snug but not tight. Seal the seam by pinching.

Use unflavored dental floss to slice 12 even rolls. Slide the floss under the log, cross the ends on top, and pull to cut. This prevents squashing and smearing.

Line a 9×13 inch pan with parchment. Space rolls evenly, swirl side up. Cover loosely and let rise until puffy and nearly touching, 30 to 45 minutes.

When pressed lightly, the dough should spring back slowly, leaving a slight indentation.

Pan options: A large cast iron skillet yields crisp edges and a golden base. A metal pan bakes faster than ceramic.

Preheat oven to 350 F. Brush the tops lightly with milk for shine.

Bake 22 to 26 minutes until deep golden on the edges and lightly golden in the center. An internal temperature near 190 F signals doneness without dryness.

If browning too quickly, tent with foil during the last 5 minutes.

Beat cream cheese until smooth. Add powdered sugar, lemon zest, lemon juice, and 1 tbsp milk. Beat until lush and pourable, adding more milk as needed. A pinch of salt sharpens the citrus.
