How long do smoothie cups last in the freezer?
Properly stored in airtight containers or freezer bags, they last 2–3 weeks. Thaw overnight in the fridge or blend directly from frozen.
Can I use natural peanut butter instead of regular?
Yes, natural peanut butter works well. The smoothie may separate slightly if the oil rises, but blending will recombine it.
What type of milk works best for blending?
Dairy milk, almond milk, oat milk, or water all work. Use 1 cup per smoothie for a thick consistency, or add more for a thinner blend.
Can I make these without protein powder?
Yes. Add Greek yogurt, nut butter, or milk powder to maintain protein content and creamy texture.
Should I slice the banana before or after freezing?
Slice before freezing—whole frozen bananas are difficult to portion and thaw unevenly.
