Prep your banana. If you want a thicker smoothie, use a frozen banana.
Peel, slice, and freeze it ahead of time. Fresh works too—just use more ice.
Add liquids first. Pour milk into the blender base. This helps the blades catch and blend smoothly.
Spoon in Nutella. Add 2 to 3 tablespoons depending on how strong you want the chocolate-hazelnut flavor.
Add banana and extras. Toss in the banana, vanilla, and a pinch of salt.
Add any optional boosters like yogurt, oats, or seeds.
Blend until smooth. Start on low, then increase to high for 30–45 seconds, scraping the sides if needed.
Adjust thickness. For a thicker smoothie, add ice or a few more banana slices. For a thinner drink, splash in extra milk.
Taste and tweak. If it’s not sweet enough, add a small drizzle of honey. If it’s too sweet, blend in more milk or a spoonful of cocoa powder.
Serve immediately. Pour into a chilled glass and enjoy right away for the best texture.
