A creamy apple cinnamon smoothie inspired by Swiss muesli - apple, oats, walnuts, and yogurt in one elegant glass

A systems based approach to wellness and beauty

Vegetarian recipe (Hanuvier standard) - no meat, poultry, fish or sea life, and no eggs. May include dairy and/or honey.

Caution - Allergen & Dietary Alerts

Please read before making, especially if preparing for others.

  • Contains tree nuts: walnut pieces in the base, and almond milk is one of the liquid options. Why: tree nuts are a major allergen; see the nut-free swap below.
  • Contains dairy: the vegetarian version uses plain Greek yogurt. Why: dairy is a major allergen; use unsweetened plant-based yogurt for a dairy-free, vegan glass.
  • Contains seeds: chia seeds in the base. Why: seed allergies, while less common, do occur; simply omit them - the smoothie will be slightly thinner.
  • Gluten status: not automatically gluten-free. Why: rolled oats are often processed alongside wheat; choose certified gluten-free oats if you are avoiding gluten.
  • Honey note: the optional sweetener can be honey or maple syrup. Why: honey is vegetarian but not vegan - use maple syrup for the vegan version.
  • Vegan option: swap the Greek yogurt for unsweetened plant-based yogurt and choose maple syrup, and the whole smoothie becomes 100% plant-based.

Nut-free option: use oat milk instead of almond milk and swap the walnut pieces for 1 extra tbsp rolled oats. Always check individual product labels, as ingredients and "may contain" warnings vary by brand.

About This Recipe

Muesli belongs to Switzerland the way croissants belong to France. In Alpine breakfast culture, oats, fruit, nuts, and dairy have long come together in one simple, practical morning bowl - food built for mountain mornings, not fuss.

This apple cinnamon smoothie takes that beloved Swiss muesli idea and blends it into a cold, creamy, drinkable breakfast for modern routines. A sweet apple gives brightness, rolled oats add gentle body, walnuts bring their quiet richness, yogurt makes it creamy, and a soft touch of cinnamon ties it all together. It tastes familiar and elegant at once - like muesli you can take with you.

Made with Greek yogurt it is a satisfying vegetarian breakfast; made with plant-based yogurt and maple syrup it becomes fully vegan. And if you would like a soft vanilla note with added plant protein, a serving of Hanuvier's Vegan Collagen Booster with 20g Plant Protein blends beautifully into this glass, integrating plant protein with collagen-supporting nutrients in a single daily serving.

Ingredients

Smoothie Base

  • 1 small sweet apple, cored and chopped (leave the peel on if tender and well washed)
  • 3/4 cup unsweetened almond milk or oat milk, chilled
  • 1/2 cup plain Greek yogurt (or unsweetened plant-based yogurt for the vegan version)
  • 2 tbsp rolled oats (certified gluten-free if needed)
  • 1 tbsp walnut pieces
  • 1 tbsp chia seeds
  • 1/4 tsp ground cinnamon
  • 1/2 tsp vanilla extract
  • 1 tsp maple syrup or honey, optional and only if needed (use maple syrup for vegan)
  • 1/4 cup ice cubes

Optional Hanuvier Vanilla Add-In

  • 1 serving Hanuvier Vegan Collagen Booster with 20g Plant Protein, Vanilla, for a soft vanilla tinge and added plant-based protein
  • 2 to 4 tbsp additional almond milk or oat milk, added only if needed to keep the smoothie drinkable

Optional Garnish

  • 1 thin apple slice
  • 1 tsp finely chopped walnuts
  • 1 tiny dusting of ground cinnamon
  • A few rolled oats sprinkled on top

Instructions

  1. Wash, core, and chop 1 small apple into 1/2-inch pieces, leaving the peel on if it is tender and well washed.
  2. Pour the chilled almond milk or oat milk into the blender first - this helps the blender move smoothly and keeps the oats and chia from sticking under the blade.
  3. Add the yogurt, rolled oats, walnut pieces, chia seeds, cinnamon, and vanilla extract.
  4. Add the chopped apple and ice cubes, plus the maple syrup or honey only if your apple is not very sweet.
  5. If using, add 1 serving Hanuvier Vegan Collagen Booster with 20g Plant Protein, Vanilla - and keep extra milk nearby, because protein powder can thicken the smoothie.
  6. Blend on low for 10 seconds, then on high for 45 to 60 seconds until smooth and creamy. If too thick, add 1 tbsp milk at a time, up to 4 tbsp total.
  7. Taste and adjust carefully - 1 tsp maple syrup for more sweetness, 1 tbsp milk for a thinner texture, or a tiny pinch of cinnamon for warmth - then pour into a chilled glass and garnish if desired.

Chef's Tips

Chef's Tips

  • Pick a naturally sweet apple. Fuji, Gala, or Honeycrisp usually make the optional sweetener unnecessary - taste before you add anything.
  • Liquid always goes in first. Milk under the blade keeps oats and chia moving instead of clumping, so the texture turns out silky.
  • Keep the cinnamon gentle. A light 1/4 tsp lets the apple and walnut flavors stay clear; you can always dust a little more on top.
  • Expect it to thicken. Oats, chia, and the optional protein add-in all absorb liquid as they sit - loosen with 1 to 2 tbsp milk if the smoothie rests a while.
  • Make it ahead, within reason. It is loveliest fresh, but a covered jar in the refrigerator holds for up to 12 hours - shake well before drinking.

Wellness Connection

At Hanuvier, we see wellness and beauty as the outcome of small, interconnected daily choices rather than any single hero ingredient. This glass carries that idea into breakfast: apple brings fiber and freshness, oats add a familiar grain, walnuts and chia contribute healthy fats, and yogurt makes it creamy and satisfying - simple ingredients working alongside one another, the way a good Swiss muesli always has.

That is the heart of a systems-based approach: not one ingredient doing everything, but a repeatable, eight-minute ritual that makes the well-chosen option the easy one.

Frequently Asked Questions

Can I make this apple smoothie vegan?

Yes, easily. Use unsweetened plant-based yogurt - almond, oat, coconut, or soy - instead of Greek yogurt, and choose maple syrup rather than honey if you want a touch of sweetness. Everything else in the glass is already plant-based.

Which apple should I use?

A naturally sweet variety such as Fuji, Gala, or Honeycrisp works beautifully and usually makes added sweetener unnecessary. Tarter apples like Granny Smith give a brighter, more tangy glass - lovely too, but you may want the optional teaspoon of maple syrup.

Do I need to peel the apple?

No - if the peel is tender and the apple is well washed, leave it on. The peel carries fiber and a pretty fleck of color. If your blender is less powerful or the skin is thick, peeling gives a smoother texture.

Why did my smoothie turn so thick?

Oats, chia seeds, and protein powder all absorb liquid quickly, so the smoothie thickens as it sits. Add 1 tbsp milk at a time, up to 4 tbsp, until it is drinkable again - and if you are adding the Hanuvier serving, keep that extra milk within reach from the start.

Can I make it ahead of time?

It is nicest immediately after blending, but you can refrigerate it in a covered jar for up to 12 hours. Shake well before drinking and loosen with 1 to 2 tbsp milk if it has thickened overnight.

What is Hanuvier's systems-based approach to wellness and beauty?

The body functions as an interconnected system, with nutrients participating in multiple biological processes and often working alongside one another. Hanuvier uses this systems perspective to develop thoughtfully formulated products that support wellness, beauty, or both through a holistic approach rather than a single-ingredient focus.
