Start by peeling your ripe banana and cutting it into cubes. If you haven’t already frozen it, slice it and place it in the freezer for at least a couple of hours.
Once your banana is frozen, gather all your ingredients. You’ll need the frozen banana, almond milk, peanut butter, and vanilla extract.
In your blender, combine the frozen banana cubes, almond milk, peanut butter, and vanilla extract. If you like your milkshake extra cold and frosty, add a handful of ice cubes at this point.
Blend on high until all the ingredients are well combined and the mixture is smooth and creamy.
Give your milkshake a taste. If you prefer it sweeter, feel free to add a little honey or maple syrup. Blend again briefly to incorporate any additional sweeteners.
Pour your Healthy Milkshake into a glass or mason jar, and enjoy immediately.
