Simple ingredients, a blender, and a baking sheet are all you need for this delicious, crispy, and savory homemade cracker.

These oat crackers have been showing up in my kitchen since my son was a toddler. I was always looking for a healthy alternative to the salty, store-bought cracker he loved.

When I found a version of this recipe and discovered how easy they were to make myself, they quickly become a staple.

My son is now in college — and I’m still making these homemade crackers.

 

The original recipe came from Laurel’s Kitchen cookbook. I’ve relied on this cookbook for years and always have it accessible. It’s a vintage mainstay for sure.

I’ve adapted the original recipe over the years.

Homemade Crackers Ingredients

You probably already have the 4 ingredients needed for these homemade crackers. Here’s what you need:

Nuts:
I use walnuts but you can use whichever nut you like.

Oats:
There is no flour in this easy cracker recipe.

Seasoning:
For the basic recipe, all you need is salt with added baking powder. Keep reading for seasonings you can use to add variation.

Milk:
Used as a binder. I have tested this recipe also with oat milk for a dairy-free application and it works well too. The cracker texture is a bit more delicate but delicious.

Seasoning Combination for Snack Crackers

Although the original Laurel’s Kitchen cracker recipe did not include seasoning, I do love the flavor it brings. Making these snack crackers even more delicious.

If you’d like to add seasoning, try 2 to 2½ teaspoons Italian Seasoning plus:

  • garlic powder
  • ground cumin
  • paprika or smoked paprika

We’re a big fan of Everything but Bagel seasoning. Much like our Everything Bagel Pretzels, this seasoning works equally well with the cracker. Add 2 to 2½ teaspoons instead of the Italian Seasoning.

How to Make Homemade Crackers

Preheat the oven to 350 degrees F. 

Step 1: Blend the Cracker Batter

Add the walnuts, oats, salt, pepper, baking powder, and seasoning into a blender or food processor. Stir in the milk and blend until smooth.

Step 2: Spread the Cracker Batter

Spread the batter onto the prepared baking sheet with an offset spatula or rubber spatula. Spread as thin and evenly as possible. Try to make sure the middle of the batter is not thicker than the sides. This will help the crackers cook evenly.

Step 3: Bake the Crackers

Bake slowly until delicately golden. After 10 minutes, remove from the oven and score into squares or rectangles using a pastry wheel or sharp knife.

Step 4: Cut into Squares

Return to the oven and continue baking until dry and done; about 20 to 25 minutes more. Thinner crackers at the edges will bake quicker than thicker ones.

Watch your oven. If outside crackers bake quicker, remove them from the baking sheet and return them it to the oven.

Once browned, remove from the oven and immediately loosen from the baking sheet. This will help keep them crisp rather than crumbly. They will continue to crisp as they cool.

Storage for Homemade Crackers

Homemade crackers are different than store-bought crackers and need to be stored differently as well.

These crackers store at room temperature for about a week. Here’s how I store them:

  • Store homemade crackers in a container that isn’t completely sealed. If storing in a jar, leave the lid ajar or loose to keep the crackers crispy. 
  • Recrisping crackers. If you want to re-crisp these homemade crackers, heat them in a 225-degree oven for 15 minutes.

Notes

Dairy Milk Substitutions:

I've tested this recipe using oat milk for a non-dairy application. It works beautifully measure for measure. The cracker texture is a bit more delicate though.

Seasoning Flavor Variations:

Although seasoning is optional, I do love the flavor it brings. If you'd like to add seasoning try:

2 teaspoons Italian Seasoning plus:

  • garlic powder
  • ground cumin
  • paprika or smoked paprika
  • sprinkle with flaked sea salt
  • or try Everything but the Bagel seasoning instead.

  1. I have made these at least 10 times. I wish I would have thought to spray
    the parchment paper first. I ate them anyway with different small variations, caraway seed, bagel seasoning, but I LOVE THIS RECIPE. My last batch came out great using cooking spray this time around. I ate ALL the other recipes as well, lots of crumbs though. This time, they actually look like crackers 🙂
    Thank you so much for this HEALTHY recipe. It’s my GO TO snack everyday with a frozen kefir smoothie.

    1. You have no idea how happy this makes me! Thank you for sharing and letting me know how you like it. I started making them with a toddler and found they satisfy those snack cravings every time. I love your variations!! Excellent advice on the parchment too. Nonstick half-sheets work well too!

  2. First try they were way too salty, and the mixture that shows poured out to the blender, was so thick I could hardly dig it out. 2nd time I reduced salt to 1 tsp, and added about 3/4 cup of water, could even have added more I think…

    1. Hi Beth, I’ve never had the batter too thick, it’s always pourable for me. But salting to taste is definitely a great idea!!

    2. Yes.- just tried it
      Was so thick for me too. Very hard to scratch it out of the blender. Next time I
      Will definitely add more liquid (water/milk)

    1. Hi Caro – they are really good, I hope you like them. I would use the biggest sheet pan available. In my case, that’s a half sheet size.

      1. Thank you Stephanie. I am going to make them this afternoon. Forgot to buy crackers and don’t feel like going to the store now. Looking forward to baking and tasting!

  3. Hi Stephanie. I can’t wait to try these crackers! I am wondering if you think a milk substitute would work well (dairy free)? I think I will sprinkle the tops of some with Parmesan cheese! Thank you so much for providing this recipe. I’ve been making my own oat flour lately, seems this would be considered baking with oat flour, nowadays. Probably not so much when your son was young. Also, thanks for the heads up on the amount of salt. I use very little these days so that helpful hint is much appreciated! I’ll let you know how they turned out! 🙂

    1. Hi Lisa! I love the idea of a milk substitute but I’ve not tried it. You have me thinking though and I plan to make some this week with almond milk. My only concern is that milk serves as a binder because of the protein so I’m not sure what the resulting texture will be.

      When Brent (my son) was little, I honestly didn’t use anything other than wheat flour– but I did try to include a variety of grains! He craved milk from morning to night and had no food allergies other than a picky pallet. His pediatrician advised me against worrying about the milk intake and today, in college, he is 6’9″. I’m almost 5’3″ – so I guess the milk didn’t hurt him :)!

      1. Lol Stephanie, I would say not. I’m not vegan but I do use rice milk for the cholesterol aspect and I have a slight intolerance to dairy. However, I agree, I think for binding the dairy milk is probably best. Can’t wait to try them! Thanks again.

      2. Oh my gosh, 6’9″ :0 I’m only 5’0 and my brother is 5’11., he was a big milk drinker too. Hm, maybe drinking milk really does improve growth! Should’ve drank more when I had the chance :,)

  4. I made these are they are SO easy and smell INCREDIBLE! The only issue for us is that they had far too much salt in them. 2 tsp of salt caused us to have to throw them out after eating only a few.

    BUT, I am making them today with much less salt (less than half of what is called for) abs hopefully my littles and I can enjoy these.

    Thank you for the recipe and encouraging creative snacks!

    1. Hi Brittany! I’m so sorry that I didn’t see this comment until today. I’m so glad you liked the oat crackers. I’ve been making them for years for my kids as well.

      Thank you for your note on the salt. I actually cook with very little salt. A couple of readers highly suggested increasing the amount, which I did. However, I tend to agree with you. Less is sometimes better!
