I made this in a Vitamix Blender. I'm not sure if it will work in a regular blender, but you can always give it a whirl. If it doesn't work, I'll send you my address for some yumminess! :-) This could also work in the Ninja or possibly nutribullet. Can't promise though.
2 Frozen Ripe Bananas
6 Frozen Strawberries
1/8-1/4 cup frozen blueberries (your choice)
1/4-1/2 cup almond milk (start with 1/4, then add a little as needed)
1/4 tsp cinnamon
1/4 cup chopped nuts (I used raw cashews and pistachios)
1 tsp oil (I used butternut squash seed oil from Stony Brook Oils to give it a buttery flavor)
Dash of salt
First, toast nuts in sautee pan on medium with oil and salt. Let cool.
For the ice cream, add all ingredients to blender (bananas on bottom, then berries). Use 1/4 cup almond milk at first. Turn Vitamix on and slowly move up to speed 2, then three. Use the plunger to constantly push the mixture down toward the blades. Add more milk a little at a time to get the consistency desired. The ice cream should peak when you pull the plunger out and be somewhat firm, but creamy. I think I used 1/2 cup almond milk in total.
Sprinkle the nuts on top.
Note: You could add a few dark chocolate pieces to the ice cream for a chocolate berry mix.
