How to Make 2-Ingredient Chia Jam

Chia jam is super easy and delicious and can be made in 10 minutes with only fresh or frozen fruit and a spoonful of chia seeds. It doesn’t contain (or need) any sweeteners, and is awesome as a topping for oatmeal, waffles, pancakes, etc. Check out this post for detailed instructions on how to make chia jam.

Dry Ingredients

  • 2 cups rolled oats, quick oats are fine too, or a combination
  • 1/3 cup walnut pieces, or any other nuts and seeds of choice
  • 3 tsp cinnamon
  • 1.5 tsp baking powder
  • 1 tsp salt

Wet Ingredients

  • 2 cups plant-based milk of choice, I use unsweetened soy milk
  • 3 tbsp ground flax seed
  • 1/3 cup peanut butter
  • 3 mashed bananas
  • 3 tsp vanilla

Useful Equipment


  • Preheat oven to 375° F. Lightly spray or grease a 9 x 13 baking dish with oil or line it with parchment paper.
  • In the baking dish, toss together the dry ingredients (listed above).
  • In another bowl, mash together the wet ingredients, along with the ground flax seed which acts as a binder (similar to eggs) when liquid is added.
  • Pour the liquid into the baking dish and mix everything together until well combined.
  • Bake for 35-40 minutes, until the top is golden.
  • Let cool slightly and then cut the pan into 6 bars. Enjoy warm, topped with peanut butter and a scoop of chia jam.
  • Leftovers can be stored in the fridge or frozen, and are easily reheated in a toaster, oven, or microwave.

    Are you not even allowed to say if this is “weight loss” or “maintenance”?

    • Well, that would depend on how much of it you eat. It uses 2 cups of oats, and 1 weight loss serving of oats (1 oz) is 1/4 cup, so I’d divide it into 8 servings for weight loss and 6 for maintenance. Add peanut butter for the rest of the protein and a side of fruit. It should be fairly simple to break it down, it’s just grain and protein.

  2. Ok this is another Winner. You would think that working at home, I’d have time to make breakfast every morning, but I don’t. I sort of like my sleep. So this pre-made breakfast fits the bill. Thank you Katie Gates. You’re a genius.
