Puree the strawberries in a blender until smooth, about 15 seconds. If the strawberries are frozen, microwave the berries in a bowl for 2 minutes before blending.
Transfer puree to a bowl and mix with 2 tablespoons chia seeds. Stir and then allow to sit for 20 minutes to thicken, or 1 hour for a thicker jelly. Refrigerate if you are not using it right away. Add any sweetener if desired.
Rinse the blender and add frozen bananas broken into smaller pieces, yogurt, peanut butter powder, milk, and ice. Puree until smooth, about 60 to 90 seconds.
Add the desired amount of strawberry chia jelly and peanut butter mixture into each glass.
You can use any berries for the chia jelly like blueberries, raspberries, blackberries, strawberries or a mixture.
Depending on how ripe the fruit, you can add some natural sweetener like honey, maple syrup, agave, or stevia to sweeten the chia jelly.
Add ¼ to ½ teaspoon pure vanilla extract if you like an extra kick of vanilla.
If you can make the chia jelly ahead of time, the texture is nice and thick and saves you time on prep when you are in a hurry!
If you forget to freeze the bananas, that's okay! The smoothie will just be slightly less thick but still tasty.
