If you grew up loving those soft, sweet oatmeal cream pies, you already know the vibe. Thick, chewy cookies with that fluffy cream filling in the middle.

Now imagine that… but just as big, just as thick, and actually packed with protein.

These are not tiny “diet cookies.”
These are real-deal, bakery-style sandwiches that hit like a treat but fuel like a meal.

High protein snacks
Protein snacks on the go

Easy protein snacks

Why These Are Worth Making

These cookies solve a problem most people have:
You want something sweet… but you don’t want to wreck your progress.

These:

Keep you full
Satisfy cravings
Actually give your body something useful

Each thick sandwich clocks in around 20g of protein, depending on how you build them.

That’s not a snack… that’s fuel.

What Makes These Different

Regular oatmeal cream pies?
👉 Sugar bomb, zero staying power

These?
👉 Built with protein, fiber, and structure

You’re getting:

• Protein from powder + yogurt
• Fiber from oats
• Creamy filling without the sugar overload

And yes… they’re still:

• Soft
• Thick
• Slightly messy (in a good way)
• Cream-filled and satisfying

Ingredients

For The Cookies

• Old Fashioned Oats
• Oat Flour
• Vanilla Protein Powder
• Egg
• Fat Free Plain Greek Yogurt
• Light Butter
• Brown Sugar Substitute
• Baking Soda
• Cinnamon
• Vanilla Extract
• Salt

For The Cream Filling

• Fat Free Plain Greek Yogurt
• Light Cream Cheese
• Vanilla Protein Powder
• Powdered Sweetener

Instructions 

Step 1: Prep

Preheat your oven to 350°F.
Line a baking sheet with parchment paper.

Step 2: Make The Dough

In a bowl, mix:

• Oats
• Oat flour
• Protein powder
• Baking soda
• Cinnamon
• Salt

In another bowl, mix:

• Egg
• Greek yogurt
• Light butter
• Sweetener
• Vanilla

Combine everything until it forms a thick, scoopable dough.

👉 It should look chunky and slightly sticky — not dry.

Step 3: Form Thick Cookies

Scoop large portions

Think 3 tablespoons per cookie.

Place on the baking sheet and gently flatten.

👉 Don’t make them thin — we want them thick and soft.

Step 4: Bake

Bake for about 10–12 minutes.

They should look:

• Set on the edges
• Soft in the middle

Let them cool completely so they firm up.

Step 5: Make The Filling

Mix together:

• Greek yogurt
• Cream cheese
• Protein powder
• Sweetener
• Vanilla

Beat until smooth and fluffy.

👉 This is where the magic happens.

Step 6: Assemble

Take one cookie, add a thick layer of filling, and top with another cookie.

Press gently.

Now you’ve got:
👉 A thick, stuffed, bakery-style protein sandwich

How To Make Them 20g Protein Each

If you want to hit that 20g sweet spot, here’s how:

• Use a full scoop + extra protein powder in dough
• Add protein powder to the filling
• Keep them BIG (4 sandwiches per batch)

That’s the difference between:
👉 “healthy cookie”
and
👉 actual high protein snack
