Sourdough Croissants and Cruffins

Sourdough Croissants and Cruffins

If you know anything about the pastry world, you know what croissants are and how difficult they can be to make.  But maybe a cruffin is something you haven’t heard of?

A cruffin is simply a croissant dough stuffed into a large muffin type tin, baked, then filled with all sorts of different pastry creams.

I know a lot of people have been waiting for this recipe for quite some time.  I have been hesitant to share it for a few reasons.

Flaky, buttery, tender, naturally leavened, sourdough croissants (or cruffins) that are just as tasty as any European bakery.

One of those reasons is that croissants aren’t the easiest recipe in the world to make.  In fact they could be one of the most difficult I have ever made. There is a reason there are “pastry schools”.

So I am afraid that the recipe will prove challenging and then I’ll get negative feedback saying “it doesn’t work” when in fact I use this exact recipe every week and it does work.

Another reason I have been putting off writing this recipe is because it is going to be LONG. Here is your warning: this is a very detailed recipe to ensure your best chance of success.

But if you can bear to read the recipe, watch the videos (over on Instagram because I couldn’t get them to work here. Sorry, not tech savvy.), and look at the pictures I think you have a good chance of making the most delicious, buttery, sourdough croissants and cruffins imaginable.

The croissant dough takes two days from start to finish with the option to extend it to three days if it works better in your schedule. The wait is worth it though, promise.

Sourdough Croissants (or Cruffins)

Yield: 6 large croissants or cruffins

Ingredients

100 g sourdough starter

250 g flour

30 g sugar

6 g salt

1 egg

80 g water

25 g butter, room temp

140 g butter, cold

Instructions
  1. Place the starter, flour, sugar, salt, egg, water, and room temp butter in a medium bowl and mix with your hands until everything is roughly incorporated and no dry flour remains.  It will be a bit shaggy at this point. That is okay.  Cover and let rest 30-60 minutes.
  2. After the rest period is up, dump the dough onto an un-floured counter.  Grab the dough by the middle and lift, then tuck the ends under itself (this video shows how). This is called folding the dough.  Repeat this about 3 times or until the dough is just barely smooth and is holding together nicely.  We don’t want to develop the gluten too much or it will be hard to roll later.  You want it just smooth enough that it’s holding together nicely. When done with the folds, place in the fridge for about 2 hours.
  3. When the dough has about 20 minutes left in the fridge cut a piece of parchment paper approximately 12″x 18″.  Cut the cold butter into thin slices and place in a roughly 8″ x 8″ square. Fold the parchment over the butter, encasing all of the butter in parchment.
  4. Take a rolling pin and beat the butter with the pin to flatten and warm it up a smidge.  Beat it until its flattened out a good amount the roll the butter to the edges of the parchment.  Keep rolling the butter until it is a solid sheet of butter that is slightly pliable and is about 8″ x 8″. Set aside.
  5. Take the cold dough from the fridge and place on a floured counter.  Roll the dough into a square that is big enough to fold the butter block into, about 10″ x 10″.  Place the butter block so that the corners of the butter block are at the flat sides of the dough, kind of like a diamond in a square.
  6. Fold over the corners of the dough to meet in the middle of the butter block and completely encase the butter.  Gently tap this dough with the rolling pin to secure it.  Let rest for about 15 minutes.
  7. After the rest, roll the dough to about 18″ long, not making it any wider.  Then fold the top down about 2/3 of the way, then fold the bottom to meet the top.  Tap with the rolling pin to secure. Then fold it in half again.  You’ll end up with a roughly 10″ x 3″ rectangle of folded dough. Cover and rest for another 15 minutes.  If it is warm you may need to stick it in the fridge.  The dough should feel cool, not cold but not warm at all times.
  8. After the rest is up take the dough to a floured counter again and set it so that the short side is parallel to you. Roll it longer again keeping the approximate 3″ width the same, roll it long until it is about 18″ again.
  9. Fold the top down to the middle, then fold the bottom over the top so that you have a rough square of dough. Cover and rest for 15 minutes.  Alternatively you can put this in the fridge until the next day but be sure to take it out of the fridge a couple of hours before you plan to roll the final croissants out.
  10. After the rest roll the dough to 10″ high and 1/4″ thick, the width of the dough doesn’t really matter here.  Once it is 10″ high and 1/4″ thick cut the croissants into triangles with bases 3.5″ wide.  Or cut into cruffins by cutting straight strips of 1.5″.
  11. Then roll the triangles of dough starting with the base toward you, rolling it to the tip.  Place it on a parchment lined baking sheet with the tip tucked under.  For cruffins, roll the stips of dough like a cinnamon roll and place in an extra large muffin tin like this one.
  12. Cover the shaped dough with a plastic bag (I use clean garbage bags) and leave to proof at 68*-70*f for 18-20 hours or until significantly larger (two to three times the size), with layers separating slightly and jiggly when the pan is jostled.
  13. When the croissants are done proofing pre-heat the oven to 400*f.  Brush the croissants with egg wash (just an egg mixed with a bit of water) and bake for about 25 minutes or until deeply golden. If making cruffins, cool before filling them.

Some ideas for filling cruffins are:

In order to fill the cruffins place cooled pastry cream in a piping bag fitted with a bismarck tip and squeeze gently until it starts to ooze back out of the top.

  • Okay. So you’ve totally convinced me that croissants are not in my future. At least for now. I’m so totally not into something that takes a couple of days. BUT they do look lovely! And I wish I were more enthusiastic about making them. I’ll just have to live vicariously through you on this one. 🤍

    I haven’t attempted this yet but planning to do so within the week – if I want more than 6 croissants, should I double the recipe or make two separate batches? I’m sure it’s a silly question but I know croissants are very temperamental so just want to be sure! Thanks!

    • You can double the recipe! It is the same in every way except when you roll them out for the final time to cut and shape them you will need to roll it longer in width to get it to the thickness needed. Good luck!

    WOW! These came out AMAZING! I wanted to make pain au chocolat and probably should have cut the dough into 5 instead of 6, but everything worked and they are buttery, flaky, and delicious! Thank you for putting this out there, I couldn’t find a single packet of yeast this week.

    Hi!! I made these a week or so ago and they were perfection! My only question is about the activity level of your starter. Do you use an active, bubbly starter, or does the activity of the starter not matter as much since there’s such an extended proofing time?

    • I try to use a bubbly active starter that has been fed within the last 8 hours but if it has gone a little past that you can still use it. It just might take a bit longer to proof.

  • I made these and they are amazing! The recipe is clear and easy to follow. I was happy to find a recipe with no commercial yeast. As I begin practice with croissants I am happy to have a recipe that makes just a few. I would love to email photos to you (I cannot tag on social media because I do not have that). For the folds, if others are looking for visual reference – I believe the first is a “book fold” (double fold) and the second is a “letter fold” (single fold). Thank for posting this!
