What is Fathead Dough

Fathead dough, or fat head dough (it is one of those things like blonde and blond, gray and grey...  you get the picture).  Fathead is a keto and low carb dough that is made by using mozzarella cheese to replace the gluten found in traditional flour, thus The mozzarella melts down and binds together the dough. Usually fathead is used for savory recipes, like pizza.  We changed it up a bit here since it is so versatile. Think of it like a pie crust, where it can be used for both.

The dough is a pastry style version of the famous fathead dough. Fathead is a gluten free dough typically made with almond or coconut flour. Melted mozzarella cheese is used to give it substance similar to a gluten.

The "cheese" taste tends to fade, So Together it makes the most amazing keto blueberry cobbler bars that strongly resembles the classic blueberry cobbler we all know and love from the past.

  1. HiYa❣️
    1. I can’t subscribe Help (using an iPad) Please ?
    2. Can use something other than cheese for the mozzarella cheese it’s too much cheese for me. On the flathead blueberry bars?

    • HI Joan!

      I am sorry you are having trouble subscribing via your iPad! I just ran a test and it worked fine here.

      We haven't tested the recipe with another cheese, unfortunately. The mozzarella is the lightest cheese with similar gluten effects as in regular flour which is why that's used. Hmmm... maybe try skipping it and making a crumble with the cream cheese, almond flour etc for the top of the blueberry filling?

  2. Hi there! Just made these tonight and wasn’t sure how to store them? Do they go in the fridge or stay out? Thanks!

  3. This is absolutely delicious. I split the sugar, using 1/4 cup monk sugar in the berries while cooking,and 1/4 cup swerve powdered sugar in bread mixture. Then I added a layer of uncooked berries on top of the cooked berries before adding the top bread. Thank you so much for this recipe.

  4. Can you use coconut flour in place of almond? I’m assuming the measurement would be different.

    • You can certainly try, you are correct about the measurement. If it were me, I would add a little at a time until you get a thicker consistency.
      Let us know!

  5. Yummmm!!! Ours came out SO GOOD. I cut and froze them individually because I would have ate the whole pan. 😀

  6. I would never have thought to use fathead dough for a dessert. GENIUS. I wish we could have apple, but this works fine.

  7. Thank you for this recipe, I wasn't sure we could have blueberries but once I figured it out per serving and subtracted the fiber it isn't actually that many carbs. YAY. We have tons in our fields.

    • Yes, they are great in moderation. 1 full cup of fresh blueberries is about 18 net carbs 🙂

  8. Hi,
    You don't say when or where to put almond flour so I put it with the cheeses like I do when making fat head pizza crust, but doing like your recipe says made a soupy mess instead of a dough. I had to add lots of almond flour and still a paste consistency. I went ahead and baked. I am letting I rest now while blueberries cook. What did I do wrong? Help!

    • Hi Donna,

      I am not really sure what went wrong with your dough. The flour is listed in the instructions, it gets beaten in with the butter and eggs etc. Not a single one of my recipes hits the page without being tested twice after tweaking to be just right. Did you refrigerate the dough long enough? The recipe states that the dough must get cold enough or it will be sticky.

    • Did you maybe melt the butter instead of using room temperature butter? It would be #2 in the instructions list.

  9. You call for a stick of butter, however I don't see where it is in the instructions. Would it be melted with the mozzarella and cream cheese?

    • Hi Megan!
      So sorry. I missed that completely. It is added into the instructions now. The butter gets beaten with the eggs and other ingredients in that instruction. Not with the mozzarella.
      Thank you for asking and letting me know. 🙂
