If you love the nostalgic taste of s’mores but want something that actually fits into a healthy breakfast routine, this Purely Elizabeth S’mores Overnight Oats copycat recipe might become your new favorite morning habit.
I have tested many overnight oat combinations over the years, and I can honestly say some look exciting but taste boring after two bites. Others are loaded with sugar and feel more like dessert than breakfast. This version aims for the sweet spot: rich chocolate flavor, soft creamy oats, a little crunch, and that familiar marshmallow-and-graham-cracker comfort people in the United States instantly recognize.
I also spoke with healthy-eating-minded home cooks and reviewed common nutrition advice around breakfast satiety, fiber, and balanced ingredients before creating this version. One thing came up again and again: breakfast needs to feel satisfying, not like punishment.
That is exactly what this recipe does.
A busy mom in Ohio might prep this on Sunday night for quick school mornings. A college student in Texas might make it in a mason jar between study sessions. A remote worker in Seattle could grab it from the fridge five minutes before a Zoom call. That is the beauty of overnight oats. They are practical, affordable, and surprisingly delicious.
Why People Love the Purely Elizabeth Style
Purely Elizabeth products became popular because they combine health-focused ingredients with flavors people actually crave. Instead of bland “diet food,” the brand leans into indulgent flavors with smarter ingredients.
The s’mores flavor works especially well because it mixes emotional comfort with convenience.
S’mores are deeply familiar to American life.
Think summer camping trips.
Think kids roasting marshmallows.
Think chocolate melting between graham crackers.
Now imagine that same comfort in breakfast form.
That emotional connection matters more than people think. Food experts often talk about satisfaction as part of healthy eating. If breakfast leaves you feeling emotionally unsatisfied, you may be more likely to snack later.
What Makes Overnight Oats Work?
If you have never made overnight oats before, the science is simple.
Oats absorb liquid over time.
That soaking process softens the oats without cooking. The starches in oats pull in moisture and swell, creating a creamy texture by morning.
Chia seeds help too.
When chia touches liquid, it forms a gel-like coating. This happens because soluble fiber absorbs water and thickens the mixture. If “soluble fiber” sounds technical, think of it like a sponge that creates creaminess while also helping you feel full longer.
That is why overnight oats feel so satisfying.
Why This Copycat Recipe Is Better Than Store-Bought for Many Families
Store-bought options are convenient, but homemade gives you control.
You can:
- Adjust sweetness
- Add more protein
- Reduce sugar
- Use dairy-free milk
- Control portion size
- Save money
For a family trying to manage grocery costs, that matters.
A single packaged breakfast can feel affordable until you multiply it by five weekdays and multiple family members.
Homemade wins fast.
Ingredient List
For 1 serving:

- 3/4 cup unsweetened almond milk
- 2 tablespoons Greek yogurt

Ingredient Breakdown
Rolled Oats
These are the base.
Do not use instant oats if you want better texture. Instant oats can become mushy.
Chia Seeds
Tiny but powerful.
They add fiber, thickness, and make the oats feel richer.
Almond Milk
Keeps the recipe lighter.
You can swap regular milk if preferred.
Greek Yogurt
Adds creaminess and protein.
This makes the oats taste closer to a dessert pudding texture.
Cocoa Powder
This gives real chocolate flavor without needing excessive sugar.
Maple Syrup
Natural sweetness with warm flavor.
Honey also works.
Mini Chocolate Chips
Essential for the true s’mores experience.
Graham Crackers
Without these, it is just chocolate oats.
Mini Marshmallows
This creates the signature flavor.
Vanilla + Salt
These may seem small, but they dramatically improve taste.
Salt makes sweet flavors pop.
Equipment Needed
Nothing fancy.
You need:
- 16-ounce mason jar or food container
- Measuring cups
- Measuring spoons
- Spoon for mixing
- Small bowl (optional)
- Refrigerator
Optional:
- Kitchen torch (for toasted marshmallow flavor)
A kitchen torch is not necessary, but if you want that campfire-style roasted marshmallow taste, it is fantastic.

Instructions
Step 1: Build the Base
Add oats, chia seeds, cocoa powder, and sea salt into your mason jar.
Stir lightly.
This ensures dry ingredients are evenly spread.
Step 2: Add the Creamy Ingredients
Pour in almond milk.
Add Greek yogurt, maple syrup, and vanilla extract.
If using protein powder, add it now.
Mix thoroughly.
Very important: scrape the bottom so cocoa powder does not clump.
Step 3: Add Texture
Mix in half the chocolate chips and half the graham cracker crumbs.
Save the rest for topping.
This keeps texture balanced.
Step 4: Refrigerate
Seal the jar tightly.
Place in refrigerator overnight.
Minimum chill time:
6 hours.
Best texture:
8 hours.
Step 5: Finish the S’mores Effect
In the morning, stir again.
Top with:
- Remaining chocolate chips
- Remaining graham cracker crumbs
- Mini marshmallows
Optional upgrade:
Use a kitchen torch for 5–10 seconds to toast the marshmallows.
This creates incredible flavor.
Step 6: Eat Cold or Slightly Warm
Most people eat overnight oats cold.
If you prefer warm breakfast, microwave briefly before adding toppings.
Personal Taste Test Notes
The first version I made was too healthy.
Yes, that is a real problem.
It had oats, cocoa, almond milk, and chia.
Technically fine.
Emotionally disappointing.
It tasted like responsible adulthood.
The better version came after adjusting sweetness, adding Greek yogurt, and increasing texture contrast.
That changed everything.
The graham cracker crunch matters.
The marshmallow sweetness matters.
The chocolate chips matter.
Healthy food should still feel enjoyable.
Make It Healthier
If you want a lighter version:
Use:
- Sugar-free chocolate chips
- Fewer marshmallows
- Unsweetened yogurt
- Less maple syrup
If you want more protein:
Add:
- Protein powder
- Extra Greek yogurt
- Hemp seeds
A fitness-focused friend in California uses this version after morning workouts because it feels indulgent while still supporting protein goals.
Common Mistakes
Too Thick
Add extra milk.
Even 2 tablespoons helps.
Too Thin
Add more chia seeds.
Let sit another hour.
Bland Taste
Usually needs:
- more vanilla
- small salt pinch
- slightly more sweetener
Mushy Texture
Likely caused by instant oats.
Use rolled oats.
Marshmallows Getting Weird
Add marshmallows in the morning, not overnight.
Otherwise they can become sticky and strange.
Meal Prep Tips
For busy weekdays, make multiple jars.
Example:
Sunday prep:
- Monday breakfast
- Tuesday breakfast
- Wednesday breakfast
I recommend not prepping too far ahead with graham crackers already mixed in, since crunch fades.
Instead:
Prepare base jars.
Add crunchy toppings fresh.
Kid-Friendly Version
Children often love this.
Reduce chia slightly if texture sensitivity is an issue.
Use extra mini marshmallows for picky eaters.
One parent I know says this became the “school day peace treaty breakfast” because mornings stopped becoming cereal arguments.
That sounds dramatic.
But parents understand.
Best Serving Ideas
Serve with:
- strawberries
- banana slices
- peanut butter drizzle
- espresso on the side
- cold brew coffee
Banana especially works well.
Chocolate + marshmallow + banana is a fantastic combination.
