Step 1

I have lots of information to prepare you to make homemade chocolate croissants. A complete guide to making the croissant dough, with a video and step-by-step photographs, can be found in my original croissants recipe. That post will help you get through the first several steps. Additionally, you can watch the video above to see how the chocolate croissants are shaped, which begins in step I suggest reading the whole recipe before beginning. Make room in the refrigerator for a baking sheet. In step 6 and again in step 13, you will need room for 2 baking sheets.

Step 2

Cut the butter in four 1-Tablespoon slices and place in the bowl of an electric stand mixer fitted with the dough hook attachment (or you can use a handheld mixer or no mixer, but a stand mixer is ideal). Add the flour, sugar, salt, and yeast. Turn the mixer on low-medium speed to gently combine the ingredients for 1 minute. With the mixer running, slowly pour in the milk. Once all of the milk is added, turn the mixer up to medium speed and beat the dough for at least 5 full minutes. (If you don’t have a mixer, knead by hand for 5 minutes.) The dough will be soft. It will (mostly) pull away from the sides of the bowl and if you poke it with your finger, it will bounce back. If after 5 minutes the dough is too sticky, keep the mixer running until it pulls away from the sides of the bowl.

Step 3

Remove dough from the bowl and, with floured hands, work it into a ball. Place the dough on a lightly floured silicone baking mat lined, lightly floured parchment paper lined, or lightly floured baking sheet. (I recommend a silicone baking mat because you can roll the dough out in the next step directly on top and it won’t slide all over the counter.) Gently flatten the dough out, as I do in the video above, and cover with plastic wrap or aluminum foil. Place the entire baking sheet in the refrigerator and allow the covered dough to rest in the refrigerator for 30 minutes.

Step 4

Remove the dough from the refrigerator. I like to keep the dough on the silicone baking mat when I’m rolling it in this step because the mat is nonstick and it’s a handy guide for the exact measurement. Begin flattening out the dough with your hands. You’re rolling it out into a rectangle in this step, so shaping it with your hands first helps the stretchy dough. Roll it into a 14×10-inch rectangle. The dough isn’t extremely cold after only 30 minutes in the refrigerator, so it will feel more like soft play-doh. Be precise with the measurement. The dough will want to be oval shaped, but keep working the edges with your hands and rolling pin until you have the correct size rectangle.

Step 5

Place the rolled out dough back onto the baking sheet (this is why I prefer a silicone baking mat or parchment because you can easily transfer the dough). Cover the rolled out dough with plastic wrap or aluminum foil, place the entire baking sheet in the refrigerator and allow the covered dough to rest in the refrigerator for 4 hours or overnight. (Up to 24 hours is ok.)

Step 6

In a large bowl using a hand-held mixer or stand mixer fitted with a paddle or whisk attachment, beat the butter and flour together until smooth and combined. Transfer the mixture to a silicone baking mat lined or parchment paper lined baking sheet. (Silicone baking mat is preferred because you can easily peel the butter off in the next step.) Using a spoon or small spatula, smooth out into a 7×10-inch rectangle. Be as precise as you can with this measurement. Place the entire baking sheet in the refrigerator and chill the butter layer for 30 minutes. (No need to cover it for only 30 minutes.) You want the butter layer firm, but still pliable. If it gets too firm, let it sit out on the counter for a few minutes to gently soften. The more firm the butter layer is the more difficult it will be to laminate the dough in the next step.

Step 7

In this next step, you will be rolling out the dough into a large rectangle. Do this on a lightly floured counter instead of rolling out on your silicone baking mat. The counter is typically a little cooler (great for keeping the dough cold) and the silicone baking mat is smaller than the measurement you need. Remove both the dough and butter layers from the refrigerator. Place the butter layer in the center of the dough and fold each end of the dough over it. If the butter wasn’t an exact 7×10-inch rectangle, use a pizza cutter or sharp knife to even out the edges. Seal the dough edges over the butter layer as best you can with your fingers. On a lightly floured counter, roll the dough into a 10×20-inch rectangle. It’s best to roll back and forth with the shorter end of the dough facing you, like I do in the video above. Use your fingers if you need to. The dough is very cold, so it will take a lot of arm muscle to roll. Again, the dough will want to be oval shaped, but keep working it with your hands and rolling pin until you have the correct size rectangle. Fold the dough lengthwise into thirds as if you were folding a letter. This was the 1st turn.

Step 8

If the dough is now too warm to work with, place folded dough on the baking sheet, cover with plastic wrap or aluminum foil, and refrigerate for 30 minutes before the 2nd turn. I usually don’t have to.

Step 9

Turn the dough so the short end is facing you. Roll the dough out once again into a 10×20-inch rectangle, then fold the dough lengthwise into thirds as if you were folding a letter. The dough must be refrigerated between the 2nd and 3rd turn because it has been worked with a lot by this point. Place the folded dough on the baking sheet, cover with plastic wrap or aluminum foil, and refrigerate for 30 minutes before the 3rd turn.

Step 10

Roll the dough out once again into a 10×20-inch rectangle. Fold the dough lengthwise into thirds as if you were folding a letter.

Step 11

Place the folded dough on the lined baking sheet, cover with plastic wrap or aluminum foil, and refrigerate for 4 hours or overnight. (Up to 24 hours is ok.)

Step 12

At the end of the next step, you’ll need 2 baking sheets lined with silicone baking mats or parchment paper. The dough is currently on a lined baking sheet in the refrigerator, so you already have 1 prepared!

Step 13

Remove the dough from the refrigerator. On a lightly floured counter, roll the dough out into an 8×20-inch rectangle. Use your fingers if you need to. Once again, the dough is very cold, so it will take a lot of arm muscle to roll. The dough will want to be oval shaped, but keep working it with your hands and rolling pin until you have the correct size rectangle. Using a pizza cutter or sharp knife, slice the dough in half vertically. Each skinny rectangle will be 4 inches wide. Then cut 3 even slices horizontally, yielding 8 4×5-inch rectangles. See photo and video above for a visual. Cut each rectangle in half lengthwise so you have 16 2×5-inch rectangles. Work with one rectangle at a time. Using your fingers or a rolling pin, stretch it to be about 8 inches long. Do this gently as you do not want to flatten the layers. Place a few small pieces of chocolate in a single layer at one end and tightly roll the dough up around the chocolate. Make sure the end is on the bottom. Repeat with remaining dough, placing the shaped croissants on 2 lined baking sheets, 8 per sheet. Loosely cover with plastic wrap or aluminum foil and allow to rest at room temperature (no warmer! I suggest just keeping on the counter) for 1 hour, then place in the refrigerator to rest for 1 hour or up to 12 hours. (Or freeze, see freezing instructions. I prefer the shaped croissants to be cold going into the oven.

Step 14

Preheat oven to 400°F (204°C).

Step 15

Whisk the egg wash ingredients together. Remove the croissants from the refrigerator. Brush each lightly with egg wash.

Step 16

Bake until croissants are golden brown, about 20 minutes. Rotate the pans halfway through baking. If croissants show signs of darkening too quickly, reduce the oven to 375°F (190°C).

Step 17

Remove chocolate croissants from the oven and place on a wire rack to cool for a few minutes before serving. They will slightly deflate as they cool. If desired, dust with confectioners’ sugar before serving.

Step 18

Croissants taste best the same day they’re baked. Cover any leftover croissants and store at room temperature for a few days or in the refrigerator for up to 1 week. You can also freeze for up to 3 months, then thaw on the counter or overnight in the refrigerator. Warm up to your liking.
