Ingredients

  • Blueberries
  • Oats
  • Dates
  • Lemon juice

Blueberries: I used fresh blueberries since they are in season right now though these cookies can also be made with frozen blueberries. The blueberries are blended until they become a smooth puree.

Oats: Rolled oats, also known as old fashioned oats, are used to help absorb the excess moisture in the cookie dough.

Dates: Dates naturally sweeten the cookies and help bind the oats.

Lemon juice: A little lemon juice is added to prevent the blueberries from oxidizing too much, allowing them to stay a vibrant purple. You can leave out the lemon juice, but the cookies will be more of a light gray blue color.

How to Make No Bake Blueberry Cookies

  • The blueberries and lemon juice are blended until smooth. Working quickly, pour the mixture out of the blender and into a small mixing bowl.
  • Add dates to a food processor. Blend until you have a smooth date paste.
  • Add blueberry puree and blend again until the two are evenly combined. Add the oats and mix until a thick dough forms.
  • Use a 1.5 tablespoon cookie scoop to scoop the dough and release onto your prepared tray.
  • Flatten each dough ball to a round disk about 1/2 inch thick. Place the cookies into the fridge for about 30 minutes to allow them to set a little firmer before eating.

Expert Tips

  • When you blend the blueberry puree, it will start thickening to a gelatin-like consistency within minutes, so it is important to pour it out of the blender and into a bowl before it begins to thicken, otherwise it becomes very difficult to remove from the blender. Once transferred to a bowl, you can allow it to thicken in the mixing bowl. You do want it to be thickened before adding it to the date paste.
  • The amount of oats needed will vary slightly depending on how much moisture is in your dates and blueberries. You may need to add more oats if your dough seems too wet.
  • You can add more dates if you want the cookies to be sweeter. Or you can add sweet mix-ins. You can also drizzle chocolate on top of the cookies.

Ingredients

  • 3/4 cup (112g) fresh blueberries
  • 1 tsp (5ml) lemon juice
  • 3/4 cup (120g) pitted Medjool dates
  • 1 1/2 cups (135g) rolled oats

Instructions
 

  • Line a baking sheet with parchment paper. Set aside.
  • Add blueberries and lemon juice to a high powered blender. I like using a small high powered blender, like a Nutribullet, because it blends small quantitites easier, but you can use a regular-sized blender. Blend for a few minutes until the blueberry mixture is very smooth with no visible flecks of skin remaining. Stop and scrape the sides of the blender if needed to help the blender blend. As soon as the puree is ready, immediately pour out the puree into a small mixing bowl. It's important to remove the blueberry puree from the blender immediately because it will start to thicken and gel after 1-2 minutes, which will make it very difficult to remove from the blender. Let the mixture thicken in the mixing bowl.
  • Add dates to a food processor. If your dates are dry, you will need to soak them first. See notes section for soaking dates. Blend the dates in your food processor until you have a smooth date paste.
  • Add the thickened blueberry puree into the food processor (it should slide out of the mixing bowl in one clump because it should be gelatin-like). Blend on low speed until the blueberry puree and date paste are evenly combined.
  • Add in the oats. Mix until the oats are evenly incorporated and a thick dough forms. The dough should be thick enough to roll and shape. If your dough seems too wet, add more oats until it is thick enough. If it seems too crumbly and doesn't seem to stick together, you can add a little more dates to help bind. You can also add a little more dates if you find the cookie dough is not sweet enough for your liking.
  • Use a 1.5 tbsp cookie scoop to scoop the dough and release onto your prepared baking tray. Use the palm of your hand or the back of a metal spoon to flatten and shape each scoop into a round disk that is about 1/2 inch thick. You can use a spoon to help smooth the edges so the cookies are perfectly round. The cookies will not change shape, so shape them how you want the final outcome to be.
  • Cover the tray with plastic wrap. Place the cookies into the fridge for about 30-60 minutes to firm up a little more. The cookies are then ready to eat. Store any uneaten cookies in an airtight container in the fridge.

Notes

  • Dates note: If you are using a fresh new package of dates or your dates feel soft, you don't need to soften them and can use them as they are. If you are using an older package of dates or your dates seem dry, you will need to rehydrate and soften the dates first. To rehydrate them, soak them in warm water for 10-15 minutes. Then drain out the water and thoroughly pat dry the dates with paper towels. You will likely need to add more oats to the dough if you had to rehydrate the dates because the date paste will likely be a little wetter.
    • I prefer using whole dates and pitting them myself by breaking them in half and removing the pit. Already pitted store bought dates tend to be more firm and won't blend as well. Weight and measurement for the dates are after they have been pitted. I used Joolies Medjool Dates*
