Peel the banana and slice it into coins. Place the coins in a sealed bag in the freezer and wait until solid. You can also use store-bought frozen banana coins.
If the dates are hard, soak in boiling water for 5-10 minutes before draining and coarsely chopping. If they're soft, coarsely chop and add to blender.
Add all the ingredients to a high-powered blender and blend until completely smooth; about 90-120 seconds. Give it a taste (see note 2) and then pour into a cup and enjoy!
Notes
Note 1: Use a high-powered blender, such as a Blendtec or Vitamix, to blend the pecans and dates. If you don’t have one, soak the pecans and dates in boiling water for about 10 minutes. Drain and let them cool before adding to your mixture.Note 2: If needed, add a little honey or maple syrup to sweeten this smoothie. I’ve found with a really good and ripe banana you don’t need the additional sweetener, but this can vary. So, give your smoothie a quick taste and add a teaspoon or two as needed. Be sure to use maple syrup if you're looking for a vegan recipe.Storage: Enjoy this Butter Pecan Smoothie immediately after blending, as it doesn't store or freeze well. If you can't finish it in one sitting, consider halving the recipe.
