Whisk the warm milk, yeast, and sugar together in the bowl of your stand mixer fitted with a dough hook attachment. Cover and allow mixture to sit for about 5 minutes or until foamy on top. *If you do not own a mixer, you can do this in a large mixing bowl and in the next step, mix the dough together with a large wooden spoon/silicone spatula. A hand mixer works, but the sticky dough repeatedly gets stuck in the beaters. Mixing by hand with a wooden spoon or silicone spatula is a better choice.*

Add the butter, 2 cups (250g) of flour, and the salt. Beat on medium speed for 2 minutes, stopping and scraping down the bowl as needed to help the mixture combine. There may still be chunks of butter—that’s ok. Add the remaining 1 cup (125g) of flour, scrape down the bowl as needed, and beat on low speed until a soft dough forms and pulls away from the sides of the bowl. Dough will be soft, but not overly sticky. Beat in 2 more Tablespoons of flour if dough seems very sticky. Avoid adding more flour than you need.

Keep the dough in the mixer and beat for an additional 5 full minutes, or knead by hand on a lightly floured surface for 5 full minutes. (If you’re new to bread-baking, my How to Knead Dough video tutorial can help here.) If the dough becomes too sticky during the kneading process, sprinkle 1 teaspoon of flour at a time on the dough or on the work surface/in the bowl to make a soft, slightly tacky dough. Do not add more flour than you need because you do not want a dry dough. After kneading, the dough should still feel a little soft. Poke it with your finger—if it slowly bounces back, your dough is ready to rise. You can also do a “windowpane test” to see if your dough has been kneaded long enough: tear off a small (roughly golfball-size) piece of dough and gently stretch it out until it’s thin enough for light to pass through it. Hold it up to a window or light. Does light pass through the stretched dough without the dough tearing first? If so, your dough has been kneaded long enough and is ready to rise. If not, keep kneading until it passes the windowpane test.

Lightly grease a large bowl with oil or use nonstick spray. Place the dough in the bowl, turning it to coat all sides of the dough in the oil. Tightly cover the bowl and allow the dough to rise in a relatively warm environment for around 2 hours or until nearly double in size. (For a tiny reduction in rise time, see my answer to Where Should Dough Rise? in my Baking with Yeast Guide.)

Gently punch down the dough to release the air. Place dough on a lightly floured silicone baking mat– or parchment paper-lined baking sheet. (I highly recommend a silicone baking mat because you can roll the dough out in the next steps directly on top and it won’t slide all over the counter.) Gently flatten the dough out into a 10×14-inch (25x36cm) rectangle using lightly floured hands to carefully stretch, but not tear, the dough. (You could also use a floured rolling pin.) Lightly cover and place the entire baking sheet in the refrigerator, and allow the covered dough to rest and chill for 20 minutes. Do not extend this time.

Make sure the butter is slightly softened but still cool—between 60–64°F (15–18°C) is ideal. Using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter and 1 Tablespoon flour together until completely combined. It’s important to note the following 3 tips before you begin laminating: (1) Have a bowl of flour at hand to continually flour your surface and rolling pin as needed. If the dough tears and butter is exposed, sprinkle the exposed butter with flour. (2) If the dough is impossible to roll, try flipping it over. If it’s still impossible to roll, cover and let it rest for 5 minutes before trying again, to let the gluten relax. (3) Do not extend the refrigeration times, because the folded dough will begin to over-expand, and it will also become very difficult to roll out.

Remove dough from the refrigerator and set the baking sheet aside. I like to keep the dough on the silicone baking mat when I’m rolling it because the mat is nonstick. Working with the longer (14-inch) edge in front of you, spread the beaten butter down the center of the dough, covering the center third of the dough. Fold one dough edge over on top of butter, and fold other edge on top of that (like folding a business letter). Pinch/seal the two short ends to enclose butter inside. Rotate dough so the long edge is horizontally in front of you. Lightly flour the top of the folded dough and, using a lightly floured rolling pin, roll out to a 9×12-inch (23x30cm) rectangle. Fold dough edges over on top like folding a business letter. Cover dough, place back on baking sheet, and refrigerate 20 minutes. Do not extend this time.

Lightly grease a standard 12-cup muffin pan. In a medium bowl, mix together the sugar and cinnamon. Remove dough from the refrigerator and set baking sheet aside. Place the chilled dough on a cutting board and cut into 3 even rolls. (You can also cut the dough into thirds right on the silicone baking mat, but make sure you are not using a super sharp knife on your baking mat—I use a bench scraper.)

(Note: this step can get messy!) Lightly flour your work surface and rolling pin. Working with one portion of dough at a time, roll out to an 8×12-inch rectangle. If it keeps shrinking back as you try to roll it out, let it rest for 5 minutes and then try again. It will eventually relax enough to get to 12 inches in length. Sprinkle evenly with 2 Tablespoons of cinnamon-sugar, and use the back of a spoon or a spatula to press it down into the dough. With a pizza cutter or sharp knife, cut 12 1-inch strips of dough. You can mark them out first with a ruler/measuring tape and a knife. Working with 3 strips at a time, layer them on top of one another. Roll them up together in a spiral and tuck the ends underneath. Place in one cup of the prepared muffin pan. Repeat this step with the remaining 2 portions of dough to get 12 cruffins.

Cover cruffins lightly and allow to rise for 1 hour, until puffy.

Preheat the oven to 350°F (177°C).

Bake for 25–28 minutes, or until the internal temperature reaches 200°F (93°C). Remove from the oven and let the cruffins slightly cool in the pan set on a cooling rack.

Once cool enough to handle, roll each cruffin in the remaining cinnamon-sugar. At this point you can enjoy the cruffins plain, or fill them with your filling of choice. Fill a piping bag (reusable or disposable) fitted with a long, skinny filling tip, such as Wilton 230, with the filling. Poke a hole 3/4 of the way down into the cruffin with a skewer (or just insert the long piping tip) and squeeze to fill the cruffin.

Cover and store leftover cruffins at room temperature for up to 3 days.
