Welcome back to Croissant Class! You have made it to Week Four, which means you have a butter block, you have locked it into your dough, and you have completed your first double fold in Week Three. Your dough has been resting in the refrigerator and the layers you have already built are sitting in there waiting for you.
This week we are doing the single fold, and this is where your lamination really starts to come together. The combination of the double fold from last week followed by the single fold this week creates the exact layer structure that gives a croissant that signature shatter at first bite. I am also going to show you my 45 degree angle rollout method and break down why a sharp knife beats a pastry wheel for trimming your dough every single time.
The Master Croissant Recipe and Masterclass Guide is available if you are ready to put every week of this class into a full recipe with detailed guidance from start to finish.

Before You Begin: Temperature Checks
At this point you have already mixed and properly fermented your dough, prepared and encased your butter block, completed the initial rollout and double fold, and rested the dough in the refrigerator for at least an hour. Now it is time for the single fold, and temperature still matters just as much as it did on day one.
The ideal dough temperature going into this step is 50 to 55°F (10 to 13°C). Here is how to check it without a thermometer:
The Press Test: Press your fingertip gently into the dough. It should leave a slight indent that slowly springs back.
The Flexibility Test: Gently lift one corner of the dough about an inch. It should bend without cracking (too cold) or drooping (too warm).
The Palm Test: Place your palm flat on the dough for three seconds. It should feel cool but not ice cold.
The Edge Check: The edges should feel firm but not brittle. This is where butter breakthrough most often starts, so pay attention here.
Check at least three spots including the center and both edges, since different parts of the dough can be at different temperatures.
Step One: Prepare the Dough
Remove your rested dough from the refrigerator and let it sit at room temperature for 5 to 10 minutes to temper slightly. Lightly dust your work surface with flour.
Before you start rolling, use the toothpick venting technique to prevent air bubbles from forming between your layers:
Take a clean toothpick and carefully poke small holes around the edges of the dough at approximately one inch intervals. Do not press too deeply, just enough to create tiny vents about one quarter inch deep. Pay extra attention to corners and thicker sections where air is most likely to get trapped. If you notice bubbles forming during rolling, add a few more vents as needed.
This is a gentler alternative to trimming the edges right away, and it is much more forgiving for anyone still getting comfortable with laminated dough.
Step Two: The Tapping Method
Before you apply real rolling pressure, start with the tapping method just like you did in Week Three.
Hold your rolling pin with both hands toward the ends of the pin. Gently tap and press down across the surface of the dough, starting at the bottom and working toward the top. This wakes up the butter and helps it distribute evenly before rolling begins. Pay extra attention to the edges, where the butter tends to be coldest.
If the dough starts to feel sticky or overly soft during tapping, cover it lightly with plastic wrap and return it to the refrigerator immediately before continuing.
Step Three: Rolling Technique
Position your rolling pin in the middle of the dough. Apply gentle, even pressure as you roll from the middle toward the top edge. Return to the middle and roll toward the bottom edge. Continue this middle-out pattern, gradually working across the entire surface toward the measurements your specific recipe requires.
To even out the outer edges, place your rolling pin vertically and roll from the middle out to each side.
Keep your palms on the ends of the rolling pin rather than gripping toward the middle. This gives you more consistent, even pressure across the full width of the dough.
Temperature management during rolling: Roll with purpose, not speed. Quick, forceful rolling generates heat and friction. Use a light touch, check the dough temperature frequently with the palm test, and monitor the edges closely since they warm faster than the center. Short, controlled strokes preserve temperature better than long sweeping ones. If the dough starts to feel soft or loses its cool feel, stop and refrigerate for 5 to 10 minutes.
Step Three A: The 45 Degree Angle Method (Optional)
This is where the magic happens, and it is worth understanding why it works.
When you roll laminated dough repeatedly in the same direction, the gluten strands align in parallel lines. That creates weak spots between layers and uneven rising. The 45 degree turn changes the direction of those gluten strands with each fold, creating a stronger, more even network throughout the dough. It also distributes the butter more evenly, creates more consistent and parallel layers, reduces the risk of butter breaking through, and promotes more uniform lift during baking.
Here is how to do it:
After rolling your dough to the size your recipe requires, lift the dough carefully and rotate it 45 degrees clockwise or counterclockwise. If you would rather not move the dough, just move your own position around the work surface instead. Roll again using your standard middle to top and middle to bottom method. Because the dough is now at an angle, you are actually rolling diagonally across the previous gluten formation. Complete your single fold as normal from this position.
Step Four: Trimming Your Dough
Before you fold, dust any excess flour and lightly mist the surface of your dough with water and trim the top and bottom edges (the shorter sides).
Why a Sharp Knife Beats a Pastry Wheel
You have probably seen pastry chefs using a pastry wheel to trim croissant dough, and you might be wondering if that is what you should be doing too. Here is why I reach for a sharp knife instead.
Precision and control. A good sharp knife lets you feel the layers through the blade and adjust your pressure and angle accordingly. You can adapt to the specific resistance of the dough in real time.
Clean layer separation. A sharp knife with a straight edge creates a clean vertical cut through all the laminated layers. Pastry wheels can compress the layers at the edge, especially if they are not perfectly sharp, which closes off the layers you worked so hard to keep separate.
Better performance on cold dough. A knife handles firmer, colder dough much better than a wheel, which can skip or drag on dough that has not warmed up enough.
Consistent edge quality. A single, clean knife cut creates a defined edge that allows for even rise and clean layer separation during baking.
Cutting technique: Use decisive, straight-down cuts rather than any sawing or dragging motion. Apply firm, even pressure in a single stroke when possible. For thicker dough, a gentle rocking motion works well without any horizontal dragging. A dull blade is your enemy here. It will compress the layers together rather than cutting cleanly through them.
Both tools have their place and many professional bakers use both depending on the task. But for home bakers working through this class, a sharp knife gives you more control and more consistent results.
Step Five: The Single Fold
Place your dough on a lightly floured surface with the shorter sides at the top and bottom. Mist the surface lightly with water. Trim the top and bottom edges if you have not done so already.
Mentally divide your dough into three equal horizontal sections. You can use the edge of your bench scraper to make very light, barely-there indentations as visual guides. Do not cut into the dough, just mark it gently.
Executing the fold:
Starting from the bottom edge, fold approximately two thirds of the dough upward. The bottom edge should now align with or slightly beyond the top third marker.
Then fold the remaining top third down over the already folded portion.
The top edge should now reach the bottom edge of the dough, creating a neat three-layer rectangle.
Gently press the edges to seal them, being careful not to trap air bubbles. Use the palm of your hand to square off any uneven edges and make sure your corners are as close to 90 degree angles as possible.
Step Six: Rest and Chill
Wrap your folded dough tightly in plastic wrap and refrigerate for at least one hour, or as long as your specific recipe requires, before moving on to the next step.
Why This Combination Works
Starting with a double fold in Week Three and then transitioning to the single fold this week is a deliberate choice and here is why it produces better croissants.
Perfect layer count. The initial double fold creates your base structure. The subsequent single fold refines and multiplies those layers without overdoing it and creating too many thin, fragile sheets.
Butter integrity. Using single folds after the initial double reduces the risk of butter breakthrough during the later stages when the dough is thinner and more vulnerable.
Controlled gluten development. The combination of fold types minimizes excessive handling at the moments when the dough is most at risk.
Temperature advantage. A single fold is faster to execute than a double, which helps you maintain that critical cool temperature throughout.
Efficiency. This hybrid approach creates the optimal number of layers in less time and with less physical stress on the dough than traditional methods that repeat the same fold type throughout.
Troubleshooting
Butter breaking through: Stop immediately and dust the spot with flour. Place the dough on a parchment lined sheet pan and refrigerate for 15 minutes. Resume with a lighter touch and in a cooler environment.
Dough springing back: The dough is telling you it needs rest. Cover it and let it relax in the refrigerator for 10 to 15 minutes. The resistance you are feeling is actually a sign of good gluten development, so do not be discouraged by it.
Uneven layers: Focus on even pressure when rolling and try the 45 degree method if you have not already. It specifically addresses uneven layer distribution.
