Why you will love this smoothie recipe

  • Quick and easy to make – smoothies are a great way to get in a filling meal when you are short on time. All you have to do is measure the ingredients and blend. You can even eat your smoothies on the go, making them perfect for busy mornings.
  • Simple ingredients – you likely have everything you need to make this blackberry oatmeal smoothie on hand right now. If you are missing an ingredient, be sure to check out the other additions section or substitutions for more ideas on what to add.
  • No banana – this thick, creamy smoothie is made without banana. Instead, oats are  used to make this smoothie thick and creamy and the smoothie is naturally sweetened with just a touch of honey or maple syrup.

Ingredients

  • Frozen blackberries – you can buy frozen blackberries or freeze them yourself for smoothies. Frozen berries helps to make the smoothie creamy and help make it cold (which to me makes the smoothie more refreshing and delicious). If you only have fresh blackberries, add about ¼-1/2 cup of ice (just a handful) and reduce the dairy free milk by ¼ cup.
  • Dairy free milk – use whatever dairy free milk you have on hand – almond milk, oat milk, cashew milk, coconut milk (in the carton or in the can), flax milk, etc. You could also use water + a tablespoon of your favorite nut or seed butter in place of dairy free milk.
  • Oats – you can use rolled oats or quick oats in this recipe. The oats help to create a thick and creamy texture and also add fiber and protein to the smoothie. I do not recommend using steel cut oats, as they have a thick hull that will make the smoothie gritty.
  • Chia seeds – chia seeds help to thicken the smoothie and are a great source of fiber. The chia seeds really help to make this smoothie super filling. You could also use ground flax seeds.
  • Honey or maple syrup – this smoothie is lightly sweetened with honey or maple syrup. If you want to keep the sugars down, you can omit this, but I prefer the flavor with a little added sweetener. You could also use pitted medjool dates, dried figs or a ripe banana instead if you want to use fruit to sweeten the smoothie naturally.

How to make a blackberry oatmeal smoothie

  • Measure the ingredients into a high speed blender in the order listed.
  • Blend on high until smooth. Enjoy immediately.

Top tips

  • Use frozen fruit for the best texture and taste in this berry oat smoothie. Frozen fruit helps to make the smoothies more thick and creamy. It also helps to make the smoothies cold, so you don’t have to add any additional ice. If you only have fresh fruit, add about 1/4-1/2 cup of ice and reduce the liquid by 1/4 cup.
  • Add more or less liquid to make the smoothie thicker or thinner.
  • Use a high speed blender. Blackberry seeds and chia seeds can sometimes get stuck in your teeth if not blended fully. If you don’t have a high speed blender, you may want to use blueberries, strawberries or raspberries in place of the blackberries and use ground chia seeds or replace the chia seeds with ground flax.

Other additions

  • Creaminess: Avocado, cashews, coconut milk, nut butter or greek style yogurt, banana
  • Sweetness: More honey or maple syrup, or add pitted dates, dried figs or a ripe banana
  • Veggies: 1/2 cup of frozen cauliflower, frozen spinach, frozen kale or zucchini (fresh or frozen)
  • Protein: Hemp hearts, greek style yogurt, protein powder, collagen peptides
  • Healthy fats: Nuts or seeds, almond butter, peanut butter, tahini, sunbutter, cashew butter, avocado, canned coconut milk

Common questions

Can you use fresh berries in this recipe?

Frozen berries help to make this smoothie thick and creamy, but you can use fresh berries if that is all you have on hand. If you are using fresh berries, add 1/4-1/2 cup of ice to get the same creamy consistency and reduce the liquid in this recipe by 1/4 cup. 

Other fruit you can use in this berry oatmeal smoothie

  • Strawberries
  • Blueberries
  • Raspberries
  • Dark sweet cherries
  • Mango
  • Peaches
  • Pineapple

How to make this oatmeal blackberry smoothie more filling

Smoothies tend to be the most filling when they are a good mix of protein, healthy fats and fiber. In this recipe, the oats provide some fiber and protein, the chia seeds provide fiber and healthy fats and the blackberries are a great source of fiber. To make this smoothie even more filling, add more protein, fat or fiber (or all three).

  • Protein – adding protein to a smoothie is a great way to make it more filling. Some great additions to this blackberry smoothie would be vanilla protein powder, Greek style yogurt, hemp hearts or collagen peptides.
  • Healthy fats – healthy fats are such a wonderful way to make smoothies more satisfying. Some great options for this smoothie would be canned coconut milk, nut butter or seed butter (like almond butter, sunbutter or tahini), nuts, seeds, hemp hearts, canned coconut milk, coconut flakes.
  • Fiber – adding more fiber can also make this smoothie more filling. Some great sources of fiber that would be great in this recipe are raspberries, more oats, ground flax, vegetables, white beans.

Can you make blackberry oat smoothies in advance?

Yes, you can make this berry oat smoothie up to 24 hours in advance and store it in the fridge. I find that anything longer than 24 hours and the smoothie starts to separate, and the flavors are just not the same.

If you know you will be short on time but want to prep the smoothie more than 24 hours in advance, you can make a smoothie bag with the ingredients (except the dairy free milk) premeasured in a freezer safe bag. When you are ready to make the smoothie, simply dump the contents of the bag in the blender, add the milk and blend.

Storing leftover smoothie

This blackberry oatmeal smoothie can be made up to 24 hours in advance if stored in an airtight container in the fridge.

If you have leftover smoothie you know you won’t be enjoying in 24 hours, pour the smoothie into ice cube trays and freeze for later! When you are ready to serve, just add some extra dairy free milk to the cubes and blend until creamy. You can also use these smoothie cubes in other smoothies to add more flavor.

Substitutions

  • Blackberries – if you don’t have frozen or fresh blackberries on hand, you can use any fruit you have. Strawberries, blueberries, raspberries, cherries, peaches, pineapple or mango would all be great in this recipe.
  • Dairy free milk – if you don’t have dairy free milk on hand, simply use 1 cup of water + 1 tablespoon of your favorite nut or seed butter (almond butter, sunbutter, tahini, cashew butter). You could also use regular dairy milk if you can tolerate dairy. 
  • Oats – use rolled oats or quick cooking oats in this recipe. If you don’t have oats on hand, you could add Greek style yogurt, banana or frozen cauliflower rice or frozen spinach/kale in place of the oats to get a similar texture in the smoothie.
  • Chia seeds – chia seeds really help to thicken the smoothie. You can also use ground chia seeds (sometimes called chia protein) or ground flax seeds in place of the chia seeds. If you don’t have chia seeds, you could use a serving of plant based protein powder or reduce the liquid to ¾ cup of milk.
  • Honey or maple syrup – this helps to elevate the sweetness of the recipe. You could also use pitted dates, dried figs, or a ripe banana to naturally sweeten the smoothie.
