Servings, Prep Time, Cooking Time, Calories

Servings: 1 generous jar (about 12–14 oz)
Prep Time: 5 minutes
Cooking Time: 0 minutes (overnight chill: 4–12 hours)
Calories: ~420 per serving (varies by protein powder and add-ins)

Things You’ll Need on Hand

Rolled oats: 1/2 cup (old-fashioned; not quick or steel-cut)
Pumpkin purée: 1/3 cup (100% pumpkin, not pie filling)
Protein powder: 1 scoop (25–30 g; vanilla or unflavored works best)
Milk of choice: 2/3 cup (dairy or unsweetened almond/oat milk)
Greek yogurt: 1/4 cup (adds creaminess and extra protein; use dairy-free if needed)
Chia seeds: 1 tablespoon (for thickness and fiber)
Maple syrup or honey: 1–2 teaspoons (optional, adjust to taste)
Pumpkin pie spice: 1 teaspoon (or 3/4 tsp cinnamon + 1/8 tsp nutmeg + 1/8 tsp ginger + pinch cloves)
Vanilla extract: 1/2 teaspoon
Pinch of salt: Balances sweetness and boosts flavor
Optional toppings: Toasted pecans or walnuts, cacao nibs, pumpkin seeds, a dollop of yogurt, or a drizzle of nut butter

Cooking Method

Mix the wet base: In a mason jar or bowl, whisk milk, Greek yogurt, pumpkin purée, vanilla, and sweetener until smooth.
Add dry ingredients: Stir in oats, protein powder, chia seeds, pumpkin spice, and a pinch of salt. Mix thoroughly so there are no dry pockets.
If it looks thick, add a splash more milk.
Seal and chill: Cover and refrigerate at least 4 hours, ideally overnight. The chia and oats will thicken everything to a pudding-like texture.
Stir and adjust: In the morning, give it a good stir.
Add milk if you want it looser, or more yogurt if you prefer it thicker.
Load the toppings: Finish with nuts, seeds, or a drizzle of almond butter for crunch and healthy fats. Boom—breakfast, handled.

Preservation Guide

Fridge: Keeps 3–4 days in a sealed container.
If you used dairy-free yogurt and milk, you can stretch to 4–5 days, IMO, but check smell and texture.
Make-ahead: Prep 3 jars at once. Add fresh toppings day-of to keep the crunch alive.
Freezer: Not ideal; texture suffers.
If you must, freeze without toppings, thaw overnight, and re-stir with a splash of milk.

Better-for-You Benefits

Protein for satiety: Protein powder + Greek yogurt = 30–40 g protein to keep you full and support muscle recovery.
Fiber power: Oats, chia, and pumpkin deliver soluble and insoluble fiber to steady energy and aid digestion.
Micronutrient-rich: Pumpkin is loaded with vitamin A (beta-carotene), plus potassium and antioxidants.
Smart carbs: Rolled oats provide slow-burning carbs without the mid-morning crash.
Healthy fats: Chia seeds and nut toppings add omega-3s and improve fullness signals.

Watch Out for These Traps

Using pumpkin pie filling: That’s pre-sweetened. You’ll overshoot sugar fast.
Too little liquid: Protein powder and chia thicken as they sit.
Start looser than you think; you can always tighten up later.
Quick oats or steel-cut: Quick oats get mushy; steel-cut won’t soften enough. Rolled oats are the sweet spot.
Weird protein flavors: Some powders taste… gym-floor adjacent.
Stick to vanilla or unflavored for best results.
Forgetting salt: A tiny pinch makes the pumpkin and spice pop. Don’t skip it.

Recipe Variations

Dairy-Free: Use almond or coconut milk and a coconut-based yogurt.
Pick a plant protein like pea or brown rice.
Extra Gains: Add 2 tablespoons powdered peanut butter or 1 tablespoon almond butter. More calories, more flavor.
Low-Sugar: Skip the maple syrup and use stevia or monk fruit.
Add a little extra vanilla for perceived sweetness.
Mocha Pumpkin: Stir in 1 teaspoon instant espresso and a few cacao nibs. Latte meets pie—iconic.
Apple Crunch: Fold in 1/4 cup finely diced apple and a sprinkle of cinnamon.
Top with toasted pecans.
Chocolate Pumpkin Pie: Use chocolate protein powder and add 1 teaspoon cocoa. Dessert vibes, breakfast macros.
Gut-Friendly Boost: Add 1–2 tablespoons kefir in place of some milk for extra probiotics.

FAQ

Can I eat it warm?

Yes.

Heat gently in the microwave for 30–60 seconds, stirring halfway. Add a splash of milk to keep it creamy and avoid turning it into spackle.

What if my oats are too thick in the morning?

Add 2–4 tablespoons of milk and stir well.

Protein and chia continue absorbing liquid overnight, so loosening it up is normal.

Is this gluten-free?

Use certified gluten-free oats and check that your protein powder is GF. Many are, but always read the label—surprises are overrated.

Which protein powder works best?

Whey blends dissolve easily and stay creamy.

For plant-based, pea protein works well—just add a little extra milk since it thickens more.

Can I reduce the carbs?

Use 1/3 cup oats, add an extra 1–2 tablespoons chia or hemp hearts, and keep sweetener minimal. You’ll still get a satisfying texture with fewer carbs.

How do I scale this for meal prep?

Multiply everything by 3–5 and portion into jars.

If using plant protein, add a bit more milk up front to account for thickening over several days.
