Introduction
I’ve been guarding this recipe like a secret family heirloom. These cookies? They’re my go-to when I need something that feels indulgent but won’t leave me with a sugar crash. The unexpected twist? Greek yogurt creates the most impossibly soft centers while cutting down on butter. Seriously, let me show you how to make cookies that stay soft for days (if they last that long!).

Ingredients Needed
- 1/2 cup peanut butter (natural, creamy works best)
- 1/4 cup Greek yogurt (plain, 2% or full-fat)
- 1/4 cup honey or maple syrup
- 1 egg (room temperature)
- 1 teaspoon vanilla extract
- 1/2 cup oat flour
- 1/4 cup mini chocolate chips
- 1/2 teaspoon baking powder
- Pinch of salt
Ingredient Notes
Let’s talk peanut butter for a second. While I normally reach for chunky in my PB&J sandwiches, for these cookies, creamy creates the perfect texture. If you’re using natural peanut butter (which I recommend), make sure it’s well-stirred before measuring. For the Greek yogurt, full-fat gives the richest flavor, but 2% works beautifully too. And don’t even think about using fat-free—I tried it once and the cookies just weren’t the same. Trust me on this one.
How to Make It
Step 1: Prep and Mix Wet Ingredients
Preheat your oven to 350°F and line a baking sheet with parchment paper. In a large bowl, mix peanut butter, Greek yogurt, honey (or maple syrup), egg, and vanilla until completely smooth.
Step 2: Add Dry Ingredients
Add oat flour, baking powder, and salt to your wet mixture. Stir gently until just combined, then fold in those mini chocolate chips. The dough will be softer than traditional cookie dough—that’s exactly what we want!
Step 3: Shape the Cookies
Using a cookie scoop or tablespoon, drop rounded portions of dough onto your prepared baking sheet. Gently press down to slightly flatten each cookie. They won’t spread much during baking.
Step 4: Bake and Cool
Bake for 8-10 minutes until the edges are just turning golden but the centers still look soft. They’ll seem underbaked, but that’s our secret to soft centers! Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.

Key Ingredients Breakdown + Health Benefits
Peanut Butter: Beyond adding that irresistible nutty flavor, peanut butter brings healthy fats and protein to these cookies. It’s what gives them that satisfying quality that keeps you from reaching for a second (or third… or fourth). I’ve been a peanut butter fanatic since childhood, and there’s something so comforting about its rich, stick-to-the-roof-of-your-mouth quality.
Greek Yogurt: This is my secret weapon in baking! Greek yogurt adds moisture and protein while reducing the need for butter or oil. The slight tanginess balances the sweetness perfectly and creates that tender crumb we’re after. When I first tried substituting Greek yogurt in cookies years ago, I wasn’t sure it would work—now I can’t imagine making them any other way.
Oat Flour: More fiber and nutrients than all-purpose flour, plus a subtle nutty flavor that complements the peanut butter beautifully. Oat flour also happens to make these cookies naturally gluten-free (if using certified gluten-free oats). The first time I baked with oat flour, I was amazed at how light and tender the results were—none of that dense, hockey-puck texture you might expect from healthier flours.
Mini Chocolate Chips: Because a cookie without chocolate is just a sad little disk. The mini size ensures you get chocolate in every bite without overwhelming the other flavors. Plus, they distribute more evenly throughout the dough than regular-sized chips. I’ve tried making these with dark chocolate chunks too, which makes for a more grown-up version my husband prefers.
Why This Recipe Works
The science behind these cookies is actually fascinating. The combination of protein-rich Greek yogurt and peanut butter creates a tender structure that retains moisture, while the natural sugars in honey caramelize just enough to give you those crispy edges without drying out the centers.
Traditional cookies rely on the creaming of butter and sugar to create air pockets, but these use the binding properties of egg and the moisture from Greek yogurt to achieve a similar texture with less fat. The result is a cookie with a uniquely soft center that stays that way even days later (if they last that long!).
The slightly lower baking temperature and shorter bake time are crucial too. We’re looking for the proteins in the egg to set just enough to hold everything together, but not so much that they squeeze out all the moisture. It’s a delicate balance, but when you get it right—cookie magic happens.
The mini chocolate chips distribute heat more evenly throughout the cookie than larger chunks would, helping maintain that perfect soft-center-to-crisp-edge ratio we’re after.
Is This Recipe Right for You?
These cookies are perfect for health-conscious sweet tooths (like me!), busy parents looking for better-for-you treats, athletes wanting a tasty protein boost, or anyone trying to incorporate more whole foods into their diet without giving up life’s simple pleasures.
I originally created these when I was training for a half marathon and needed something satisfying that wouldn’t derail my nutrition plan. Now they’re my go-to when I’m craving something sweet but don’t want the sugar crash that follows regular cookies.
They’re also perfect for kids’ lunchboxes or after-school snacks—substantial enough to keep energy levels stable but still exciting enough to feel like a treat.
Who Should Avoid It?
These cookies contain nuts, dairy, and eggs, so they’re not suitable for those with allergies to these ingredients. While they use oat flour instead of wheat flour (making them gluten-free if using certified GF oats), they’re not vegan due to the egg and Greek yogurt. They also contain natural sugars from honey or maple syrup, so while they’re lower in sugar than traditional cookies, they’re not sugar-free.
Customization Ideas
- Nut Butter Swap: Try almond butter or cashew butter for a different flavor profile. Sunflower seed butter works for a nut-free version!
- Mix-In Magic: Swap the chocolate chips for dried cranberries, chopped dried apricots, or white chocolate chips.
- Spice It Up: Add 1/2 teaspoon of cinnamon or a pinch of cardamom for a warming touch.
- Extra Protein: Stir in 1 tablespoon of your favorite unflavored or vanilla protein powder.
- Added Crunch: Fold in 2 tablespoons of chopped walnuts or hemp seeds for texture and omega-3s.
- Double Chocolate: Add 1 tablespoon of cocoa powder to the dough for chocolate peanut butter cookies.
Kitchen Tools You’ll Need
Nothing fancy required for these simple cookies:
- Medium mixing bowl
- Measuring cups and spoons
- Wooden spoon or rubber spatula
- Cookie scoop or tablespoon
- Baking sheet
- Parchment paper or silicone baking mat
- Wire cooling rack
I’ve made these in my tiny apartment kitchen with minimal equipment and in my parents’ fully-stocked kitchen—they turn out great either way!
Pro Tips & Common Mistakes
Watch the consistency of your peanut butter. Different brands vary wildly in thickness. If your dough seems too wet, add an extra tablespoon of oat flour. If it’s too dry, add a tiny splash of milk. The first time I made these with a new brand of peanut butter, my dough was so runny I had to add significantly more flour.
Don’t skip the parchment paper. These cookies tend to stick because of their lower fat content. I once thought I could get away with just greasing the pan—what a mess that was!
Trust the process on baking time. They will look underdone when you take them out, but they’ll continue cooking on the hot baking sheet. The one time I left them in “just a couple more minutes,” they turned out dry and crumbly.
Let the dough rest. If you have time, let the mixed dough sit for 10 minutes before scooping. This allows the oat flour to absorb moisture for a better texture. I’m usually too impatient for this step, but it does make a difference!
Storage matters. These cookies dry out faster if left uncovered. Store them in an airtight container with a piece of bread to maintain moisture.
Serving Suggestions
These versatile cookies work for so many occasions! For breakfast on the go, I grab two cookies and a banana (yes, cookies for breakfast—I’m an adult!). For an afternoon pick-me-up, one cookie with a cup of coffee provides just enough energy without the crash.
For dessert, try sandwiching a little extra Greek yogurt mixed with honey between two cookies for a healthier ice cream sandwich alternative. My kids love them crumbled over Greek yogurt with a drizzle of honey for a parfait-style treat.
When I’m feeling fancy, I’ll melt a little extra dark chocolate to drizzle over the tops before serving to guests—they look so much more impressive with minimal effort!

Storing & Freezing Guide
These cookies stay soft for 3-4 days when stored in an airtight container at room temperature. For maximum freshness, place a slice of bread in the container—the cookies will absorb moisture from the bread instead of drying out.
In the refrigerator, they’ll last about a week, though they’ll firm up slightly when cold. I actually love them straight from the fridge on hot summer days!
For longer storage, these freeze beautifully for up to 3 months. Place cookies in a single layer on a baking sheet until frozen solid, then transfer to a freezer bag. Thaw at room temperature for about 30 minutes before enjoying, or microwave for 10-15 seconds for that fresh-baked warmth.
The cookie dough also freezes well! Scoop into portions, freeze on a baking sheet, then transfer to a freezer bag. Bake straight from frozen, just add 1-2 minutes to the baking time.
FAQs
Can I use regular flour instead of oat flour? Yes! All-purpose flour works as a 1:1 substitute for oat flour in this recipe. The texture will be slightly different—less tender but more traditional. Whole wheat flour also works but will give a denser result and slightly nutty flavor.
My cookies spread too much. What went wrong? This is usually due to too-warm dough or extra runny peanut butter. Try chilling the dough for 15-20 minutes before baking. Different brands of peanut butter have varying oil content, so you might need to adjust the flour slightly depending on what you’re using.
Can I make these vegan? I’ve successfully made these using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, left to sit for 5 minutes) and coconut yogurt instead of Greek yogurt. The texture is slightly different—more tender but less chewy—but still delicious!
My cookies turned out dry. Help! The most common culprit is overbaking. These cookies firm up significantly as they cool, so they should look slightly underdone when you take them out of the oven. Also, measure your oat flour carefully—too much can quickly dry out the dough.
