Spelt Croissants

Using Janie's Mill Spelt and whole-grain flours in these croissants produces a slightly nutty, savory flavor with all the flaky delicacy of the quintessential croissant.

This recipe is adapted from Claire Saffitz's recipe first published in the New York Times. This recipe can lean sweet and be adapted into Pain au chocolat or provide the perfect vessel for a savory sandwich.

Croissants take their flavor from their primary ingredients, flour and butter. So choose a high-quality European butter, and the best flours you can. I used equal parts of Janie's Mill Spelt flour, High-Protein Bread flour, Sifted Artisan, and Artisan Blend flours for the croissants pictured above. But since we've heard from many bakers that Janie's Mill Sifted Artisan is a tried and true base for croissants, we used that as the main flour in the following recipe.

We encourage you to experiment with a mixture of bread flours and Ancient Grains to bump up the flavor and complexity of an already impressive pastry!

Yield: 8 croissants (these are large croissants so splitting the dough into 16 instead will still yield robust pastries)


For the dough: 

For the butter block and assembly:

  • 1 ½ cups / 340 grams unsalted European or European-style butter (3 sticks), chilled
  • Flour, for rolling out the dough
  • 1 large egg yolk
  • 1 tablespoon heavy cream


  1. Twenty-four hours before serving, start the dough: In the bowl of a stand mixer fitted with the dough hook, combine the flours, sugar, salt and yeast, and stir to combine. Create a well in the center, and pour in the water and milk. Mix on low speed until a tight, smooth dough comes together around the hook, about 5 minutes. Cover the bowl with a damp towel and let rest for 10 minutes.
  2. Turn the mixer on medium-low speed. Add the chilled butter pieces all at once and continue to mix until the dough has formed a very smooth, stretchy ball that is not the least bit sticky, 5 - 8 minutes.
  3. Form the dough into a ball and place seam-side down on a lightly floured work surface. Using a sharp knife, cut two deep perpendicular slashes in the dough, forming a + sign. (This will help the dough expand into a square shape as it rises, making it easier to roll out later.) Place the dough slashed-side up inside the same mixing bowl, cover with plastic wrap and let rise at room temperature until about 1½ times its original size, 45 minutes to 1 hour. Transfer the bowl to the refrigerator and chill for at least 4 hours and up to 12. Chilling the dough makes it easier to work with but also helps to develop flavor.

  4. Make the butter block: Cut the sticks of butter in half lengthwise so they are slightly thinner. Place them side-by-side in the center of a large sheet of parchment paper, then loosely fold all four sides of the parchment over the butter to form a packet. Turn the packet over and use a rolling pin to lightly beat the cold butter into a flat scant ½-inch-thick layer, fusing the sticks and making it pliable. Turn over the packet and unwrap, replacing the parchment with a new sheet if needed. Fold the parchment paper over the butter again, this time making neat, clean folds at right angles, forming an 8-inch square. Turn the packet over again and roll the pin across the packet, further flattening the butter into a thin layer that fills the entire packet. The goal is a level and straight-edged square of butter. Transfer the butter block to the refrigerator.
  5. After the dough has chilled for 4-12 hours and has doubled in size, remove it from the refrigerator, uncover and transfer to a clean work surface. Deflate the dough with the heel of your hand and stretch the dough into a rough square measuring no more than 8 inches on one side.
  6. Place 2 pieces of plastic wrap on the work surface perpendicular to each other, and place the dough on top. Wrap the dough rectangle, maintaining the squared-off edges, then roll your pin over top as you did for the butter, forcing the dough to fill in the plastic and form an 8-inch square with straight sides and right angles. Freeze for 20 minutes.
  7. Remove the butter from the refrigerator and the dough from the freezer. Set the butter aside. Unwrap the dough and place on a lightly floured surface. Roll the dough, dusting with flour if necessary, until 16 inches long, maintaining a width of 8 inches. Brush off any flour from the surface of the dough and make sure none sticks to the surface.
  8. You’re going to enclose the butter block in the dough and roll them out together. To ensure they do so evenly, they should have the same firmness, with the dough being slightly colder than the butter. The butter should be chilled but able to bend without breaking. Unwrap the butter just so the top is exposed, then use the parchment paper to invert the block in the center of the dough rectangle, ensuring all sides are parallel. Press the butter gently into the dough and peel off the parchment paper. You should have a block of butter with overhanging dough on two opposite sides and a thin border of dough along the other two.
  9. Grasp the overhanging dough on one side and bring it over the butter toward the center, then repeat with the other side of the dough, enclosing the butter. You don’t need the dough to overlap, but you want the two sides to meet, so stretch it if necessary, and pinch the dough together along all seams so no butter peeks out anywhere. Lift the whole block and dust a bit of flour underneath, then rotate the dough 90 degrees, so the center seam is oriented vertically.
  10. Orient the rolling pin perpendicular to the seam and lightly beat the dough all along the surface to lengthen and flatten. Roll out the dough lengthwise along the seam into a 24-inch-long, ¼-inch-thick narrow slab, lightly dusting underneath and over top with more flour as needed to prevent sticking. Remember to periodically lift the dough and make sure it’s not sticking to the surface. Return the dough to the fridge for a few minutes if it starts to warm up too much.

  11. Use a wheel cutter or long, sharp knife to trim the shorter ends, removing excess dough where the butter doesn’t fully extend and squaring off the corners for a very straight-edged, even rectangle of dough. Maintaining the rectangular shape, especially at this stage, will lead to the most consistent and even lamination. If at any point in the process you see air bubbles in the dough while rolling, pierce them with a cake tester or the tip of a paring knife to deflate and proceed.
  12. Dust any flour off the dough’s surface. Grasp the short side of the rectangle farther from you and fold it toward the midline of the dough slab, aligning the sides. Press gently so the dough adheres to itself. Repeat with the other side of the dough, leaving an ⅛-inch gap where the ends meet in the middle. Now, fold the entire slab in half crosswise along the gap in the center. You should now have a rectangular packet of dough, called a “book,” that’s four layers thick. This is a “double turn,” and it has now quadrupled the number of layers of butter inside the dough.
  13. Wrap the book tightly in the reserved plastic. Freeze the dough for 15 minutes, then refrigerate for 1 hour.

  14. Let the dough sit at room temperature for about 5 minutes. Unwrap and place on a lightly floured surface. Beat the dough and roll out as before (Step 10) into another long, narrow ⅜-inch-thick slab. It should be nice and relaxed, and extend easily. Dust off any excess flour.
  15. Fold the dough in thirds like a letter, bringing the top third of the slab down and over the center third, then the bottom third up and over. This is a “simple turn,” tripling the layers. Press gently so the layers adhere. Wrap tightly in plastic again and freeze for 15 minutes, then refrigerate for 1 hour.
  16. Let the dough sit at room temperature for about 5 minutes, then unwrap and place on a lightly floured surface. Beat the dough and roll out as before, but into a 14-by-17-inch slab. The dough will start to spring back, but try to get it as close to those dimensions as possible. Brush off any excess flour, wrap tightly in plastic, and slide onto a baking sheet or cutting board. Freeze for 20 minutes, then chill overnight (8 to 12 hours).

  17. Four and a half hours before serving, arrange racks in the upper and lower thirds of the oven. Bring a skillet of water to a simmer over medium-high heat. Transfer the skillet to the floor of the oven and close the door to create a humid proofing environment. 
  18. As the steam releases in the oven, line two rimmed baking sheets with parchment paper and set aside. Let the dough sit at room temperature for about 5 minutes. Unwrap (save the plastic for proofing), place on a very lightly floured surface, and, if necessary, roll out to 17-by-14 inches. Very thoroughly dust off any excess flour with a pastry brush. Use a wheel cutter or long knife and ruler to cut the shorter sides, trimming any irregular edges where not all the layers of dough fully extend and creating a rectangle that’s exactly 16 inches long, then cut into four 4-by-14-inch rectangles.
  19. Separate the rectangles, then use the ruler and wheel cutter to slice a straight line from opposite corners of one rectangle to form two long, equal triangles. Repeat with the remaining rectangles to make 8 triangles. 
  20. Working one triangle at a time, grasp the two corners of the shorter end, the base of the crescent, and tug gently outward to extend the points and widen the base to about 3 inches. Then, gently tug outward from about halfway down the triangle all the way to the point, to both lengthen the triangle and thin the dough as it narrows. Starting at the base (the short end), snugly roll up the dough, keeping the point centered and applying light pressure. Try not to roll tightly or stretch the dough around itself. Place the crescent on one of the parchment-lined baking sheets, resting it on the point of the triangle. If the dough gets too soft while you’re working, cover the triangles and freeze for a few minutes before resuming rolling. Space them evenly on the baking sheets, four per sheet. Very loosely cover the baking sheets with plastic wrap, so the croissants have some room to expand.

  21. Open the oven and stick your hand inside: It should be humid but not hot, as the water in the skillet will have cooled. You want the croissants to proof at 70 to 75 degrees. (Any hotter and the butter will start to melt, leading to a denser croissant.) Place the baking sheets inside the oven and let the croissants proof until they’re about doubled in size, extremely puffy, and jiggle delicately when the baking sheet is gently shaken, 2 to 2½ hours. Resist the urge to touch or poke the croissants as they proof. Try not to rush this process as an underproofed croissant will not be as light. If your kitchen is on the cooler side, they may take up to an hour longer to proof.
  22. Remove the baking sheets from the oven and carefully uncover them, then transfer to the refrigerator and chill for 20 minutes while you heat the oven. Remove the skillet from the oven and heat to 375 degrees.
  23. In a small bowl, stir the yolk and heavy cream until streak-free. Using a pastry brush, gently brush the smooth surfaces of each crescent with the yolk and cream mixture, doing your best to avoid the cut sides with exposed layers of dough.
  24. Transfer the sheets to the oven and bake for 20 minutes. Rotate the baking sheets and switch racks, and continue to bake until the croissants are deeply browned, another 10 to 15 minutes. Remove from the oven and let cool completely on the baking sheets.
