Shopping List – Ingredients

• Rolled oats (old-fashioned), 1/2 cup per serving
• Ground flaxseed, 1–2 tablespoons (freshly ground is best)
• Milk of choice (dairy or unsweetened plant milk), 2/3–3/4 cup
• Plain Greek yogurt, 2–3 tablespoons (optional for creaminess and protein)
• Apple, 1 small to medium, diced or grated (Honeycrisp, Fuji, or Granny Smith)
• Chia seeds, 1 teaspoon (optional for extra thickness)
• Maple syrup or honey, 1–2 teaspoons (optional, adjust to taste)
• Cinnamon, 1/2–1 teaspoon
• Vanilla extract, 1/4 teaspoon (optional but lovely)
• Pinch of salt to amplify flavor
• Optional toppings: chopped walnuts or almonds, raisins, peanut butter/almond butter, extra apple slices, hemp seeds

Step-by-Step Instructions

1. Prep your jar: Grab a 12–16 oz jar or lidded container.

   You’ll want space for stirring and toppings.

2. Add the dry base: 1/2 cup rolled oats, 1–2 tablespoons ground flaxseed, 1 teaspoon chia seeds (optional), a pinch of salt, and 1/2–1 teaspoon cinnamon.
3. Mix the wet: Pour in 2/3–3/4 cup milk, 2–3 tablespoons Greek yogurt, 1/4 teaspoon vanilla extract, and 1–2 teaspoons maple syrup or honey. Stir thoroughly so nothing clumps at the bottom.
4. Apple time: Dice or grate one small apple. Grated equals softer, more uniform texture; diced equals crunch.

   Fold it in.

5. Adjust thickness: If you like pudding-level thick, stick with 2/3 cup milk. For looser oats, go up to 3/4 cup. You can always splash more in the morning.
6. Chill and set: Seal the jar and refrigerate for at least 4 hours, ideally overnight.

   The oats and flax will absorb liquid and thicken.

7. Morning magic: Open, stir, taste. Add a splash of milk if too thick. Top with walnuts, almond butter, extra apple, or a dusting of cinnamon.

   Devour cold or warm gently for 30–45 seconds in the microwave.

Keeping It Fresh

Storage window: Up to 3 days in the fridge is the sweet spot, especially if you’re using dairy and fresh-cut apple. By day 4, the texture can get a bit tired.

Texture insurance: If you dislike softened apple, keep the diced apple in a separate container and add it right before eating. This keeps the crunch alive.

Batch prepping: Mix the dry components (oats, flax, chia, cinnamon, salt) in small containers.

Add wet ingredients and apple the night before—assembly goes from 2 minutes to 30 seconds, IMO.

Benefits of This Recipe

• High in fiber: Oats and flaxseed support gut health, steady energy, and that pleasantly full feeling.
• Omega-3 boost: Ground flaxseed is a plant-based source of ALA, helpful for heart health and inflammation balance.
• Protein balance: Greek yogurt nudges the protein up so you’re not raiding the snack drawer at 10 a.m.
• Low-effort consistency: Consistency beats intensity. This is the kind of breakfast you can stick with for months without boredom.
• Natural sweetness: Apple plus cinnamon delivers a dessert vibe with minimal added sugar.

Don’t Make These Errors

• Using whole flax seeds: Your body can’t fully break them down. Use ground flaxseed for the nutrition win.
• Skimping on salt: A tiny pinch makes flavors pop.

  It won’t make the oats “salty,” promise.

• Overloading liquid: Soupy oats are sad oats. Start with less; you can add more later.
• Forgetting to stir: Dry pockets of oats at the bottom are a rookie mistake. Stir well before chilling.
• Using quick oats by accident: They can turn mushy overnight.

  Rolled oats hold texture better.

• Waiting too long to eat: Apples can brown and soften excessively after 3 days. Freshness matters.

Alternatives

• Dairy-free: Use almond, oat, or soy milk and skip yogurt or sub a coconut yogurt.
• High-protein boost: Add a scoop of vanilla protein powder; increase milk slightly to maintain texture.
• No-sweetener route: Skip maple/honey and rely on a sweeter apple variety plus extra cinnamon.
• Spice switch-ups: Try apple pie spice, cardamom, or nutmeg. A micro-grate of fresh ginger is elite.
• Nutty crunch: Walnuts for brain-friendly fats, almonds for crunch, or pecans for a dessert vibe.
• Warm version: Microwave 30–60 seconds in the morning, stir, and top with a spoon of almond butter.

  Cozy-town.

• Berry remix: Add a handful of blueberries or raspberries with the apple for a juicy bite and color pop.

FAQ

Can I use steel-cut oats?

You can, but use the quick-cooking steel-cut variety and increase the liquid slightly. Expect a chewier texture and let it sit a full 12 hours. Regular steel-cut oats are too firm for standard overnight timing.

Do I have to use ground flaxseed?

For nutrition, yes.

Whole flax seeds mostly pass through. If you only have whole, grind in a spice grinder or use chia seeds as a partial substitute.

How do I keep the apple from browning?

Add a squeeze of lemon when mixing the apple, or store the apple separately and add it right before eating. Using a tart apple like Granny Smith also helps with flavor balance.

Is this good for weight management?

It can be.

The combo of fiber, protein, and healthy fats supports satiety and stable energy. Just portion your sweeteners and toppings—nut butters and maple syrup add up fast.

Can I make this nut-free?

Absolutely. Skip nuts and nut milks.

Use oat or rice milk, and top with seeds like pumpkin or sunflower for crunch.

What if I don’t like cinnamon?

Use vanilla and cardamom, or a pinch of allspice. You’ll still get a warm, aromatic profile without cinnamon’s signature flavor.

How do I prevent it from getting too thick?

Use a bit more milk (up to 3/4 cup), reduce chia, and add the yogurt in the morning instead of at night. A quick splash of milk in the morning also loosens it perfectly.

Can I sweeten with dates?

Yes.

Finely chop 1–2 medjool dates and mix them in, or blend a date with the milk for even distribution. It’s caramel-like and awesome with apple.
