Multi-seed oat flour crackers are made with only a few ingredients, and are so easy to make! You may never buy boxed crackers again.

Oat flour crackers are a light, crispy, and tasty way to enjoy whole grains! They take minutes to assemble in one bowl, and are adaptable to any toppings you like. We chose sunflower, sesame, and chia seeds for this recipe because that’s what we had on hand in the cupboard. Feel free to substitute any other seeds you have on hand. Finely chopped nuts or chopped fresh herbs are also great!

Ingredients

  • oat flour
  • flax flour
  • salt
  • water
  • olive oil
  • sunflower, sesame, and chia seeds (or other seeds of your choice)
Ingredients to make oat crackers laid out on a table in small dishes.

Instructions

  • Mix the oat flour, flax flour, and salt in a bowl.
  • Add the water and olive oil and stir to combine.
  • A hand holding a rubber spatula mixing oat flour, flax flour, and salt in a glass bowl.
  • A hand pouring water from a glass jar into a glass bowl of oat flour.
  • Let the mixture sit at room temperature for 5 to 10 minutes to thicken (if you leave it for the full 10 minutes it will be very thick).
  • A hand mixing water, oil, and oat flour in a glass bowl with a rubber spatula.
  • Mixed oat cracker batter in a glass bowl with a rubber spatula.
  • Preheat the oven to 300ºF (150ºC) and cut two pieces of parchment paper to fit a baking sheet.
  • Lay one piece of parchment paper on a work surface. Turn the cracker dough out onto the paper.

  • Place the second sheet of parchment paper on top of the dough and flatten it gently with your hands.
  • Still using your hands, spread the dough between the two sheets of parchment paper to the edges. Some of the dough may ooze out from the sides. Simply lift the paper and move the dough back between the sheets.
  • A hand flattening dough between two pieces of parchment paper.
  • Two hands flattening dough between two pieces of parchment paper.
  • When the dough is spread evenly between the sheets smooth the top of the crackers gently with a rolling pin.

  • Transfer the rolled dough (still in between the paper) onto a baking sheet and remove the top layer of parchment.
  • Hands transferring rolled dough between pieces of parchment paper onto a white baking sheet.
  • A hand peeling away the top layer of parchment paper from flattened dough.
  • Sprinkle the top of the oat flour cracker dough evenly with the sunflower, sesame, and chia seeds (or whichever other seeds you’re using).

  • Bake the crackers for 20 minutes then remove the sheet from the oven. Cut the dough into crackers with a pizza cutter or sharp knife. Because these are gluten-free crackers you can expect them to be a bit crumbly.
  • Return the crackers to the oven for 30 to 35 minutes.
  • Remove the crackers from the oven and place the sheet on a rack to cool.
  • Eat the crackers as a snack, include them on a charcuterie board, or serve them with your favourite dips.

Notes & Tips

  • A Note On Oat And Flax Flours – You can purchase oat and flax flours at most grocery and bulk stores, however, you can also make your own. For instructions on how to make flax flour check out our flax egg substitute post. You can use the same process with oats to make homemade oat flour.
  • Olive Oil Substitute – Olive oil imparts a rich flavour and texture to the oat flour crackers. We recommend using it, however, you can substitute coconut oil, or any other neutral-flavoured oil if you prefer.
  • Getting The Seeds To Stick To The Crackers – Sprinkling the seeds on top of the cracker dough works fine, however you can take things a step further. After your sprinkle the seeds over the dough try placing the top sheet of parchment paper back on top of the dough and rolling it gently with a rolling pin. This method will embed the seeds directly into the crackers.
  • Storage Notes – Oat flour crackers will keep in a zip-top bag or a container with an airtight lid at room temperature for up to one week.
  • Can You Freeze Oat Flour Crackers? Crackers will keep in the freezer, stored in a zip-top bag with excess air squeezed out, for up to one month. A great grab and go snack!

      I have been making these crackers regularly for quite a while. Haven’t bought crackers ever since I discovered this recipe! I always have to make a double batch as they disappear so quickly. It’s very easy to add different herbs and seeds to change it up, too. Highy recommend trying this easy recipe if you’re looking for a healthy, versatile cracker. Thanks so much for posting this.
