Prep the fruit. If using fresh strawberries, rinse, dry, and hull them. Peel the banana.
If you like a thicker shake, use frozen banana slices or frozen strawberries.
Add liquids first. Pour milk into the blender. Adding liquids before solids helps the blades catch and blend smoothly.
Layer in the fruit and extras. Add the banana, strawberries, yogurt (if using), vanilla, and a small pinch of salt. If you’re using sweetener or any add-ins like nut butter or protein powder, add them now.
Blend until smooth. Start on low speed, then increase to high.
Blend for 30–60 seconds until creamy. If it’s too thick, add a splash more milk. If it’s too thin, add a few ice cubes or more frozen fruit and blend again.
Taste and adjust. Give it a quick taste.
If you want it sweeter, add a bit more honey or maple syrup. If you want more strawberry punch, toss in a few extra berries.
Serve immediately. Pour into a chilled glass. For fun, top with a sliced strawberry, banana coins, or a sprinkle of chia seeds.
