Greek Yogurt Chia Seed Cookies

Soft & Healthy

Warm, tangy, and studded with tiny crunches, these cookies bake up soft and lightly chewy. Greek Yogurt Chia Seed Cookies deliver protein and a gentle tang from yogurt while chia adds texture and fiber. After testing this recipe 10 times with different yogurts and flours, I landed on a version that stays tender for days and bakes reliably in home ovens. I developed this while refining high-protein snacks for busy mornings in a small test kitchen. The method is simple, and the dough is forgiving. Read on for precise measurements, step-by-step photos, and pro tips so you can bake them perfectly every time.

Why This Recipe Works

Greek yogurt adds moisture and tang while reducing the need for eggs. The protein tightens the crumb without drying it out.
A small amount of melted butter plus yogurt gives a tender texture that holds shape while baking.
Chia seeds absorb some liquid and add a delicate crunch without weighing the cookie down.
Minimal creaming keeps the dough from aerating too much, which preserves a soft, cake-like interior.
Gentle, short baking time prevents over-drying and keeps centers slightly soft.

Ingredients Breakdown

All-purpose flour: Provides structure. Measure by weight for best results. Substitution with 250 g (2 cups) whole-wheat flour will make cookies denser and slightly drier.
Baking powder: Leavening for light rise. Don’t use baking soda alone.
Granulated sugar + brown sugar: A mix of 120 g (2/3 cup) granulated and 50 g (1/4 cup packed) brown sugar balances sweetness and chew. All brown will make them moister and darker.
Unsalted butter: Adds richness. Use 115 g (1/2 cup) melted and cooled. If you use salted butter, reduce added salt by 1/4 teaspoon.
Greek yogurt: 180 g (3/4 cup) full-fat plain yogurt gives tang and moisture. Nonfat yogurt can be used but will yield a slightly drier cookie.
Egg: 1 large egg binds and gives lift. For egg-free, see substitutions.
Vanilla extract: 1 tsp for flavor depth.
Chia seeds: 45 g (3 tbsp) add crunch and fiber. If you use chia jam instead of seeds, bake time and texture will change; see a chia seed jam idea for a garnish swap.
Sea salt: 1/2 tsp (use Diamond Crystal for looser measure; if using Morton, halve it).
Mix-ins (optional): 80 g (1/2 cup) dark chocolate chips or 60 g (1/2 cup) chopped nuts.

Essential Equipment

Baking sheets: Two rimmed baking sheets lined with parchment or silicone mats.
Digital scale: For precise flour weight (recommended).
Medium mixing bowls and one large bowl.
Rubber spatula and whisk.
Cookie scoop (1.5 tbsp) for uniform cookies. If you don’t have a scoop, use two spoons.
Cooling rack. No stand mixer needed — hand mixing is fine.

Step-by-Step Instructions

Prep Time: 15 minutes | Cook Time: 12 minutes | Inactive Time: None | Total Time: 27 minutes | Servings: 24 cookies (1 cookie per serving)

Step 1: Preheat and prepare pans

Preheat your oven to 175°C (350°F). Line two baking sheets with parchment paper and set a cooling rack nearby. Rotate sheets between racks halfway through baking if your oven has hotspots.

Step 2: Combine dry ingredients

Whisk together 300 g (2 1/2 cups) all-purpose flour, 1 tsp baking powder, and 1/2 tsp sea salt in a medium bowl until evenly mixed. This ensures the leavening distributes and prevents pockets of powder.

Step 3: Mix wet ingredients

In a large bowl, whisk 115 g (1/2 cup) melted and cooled unsalted butter with 120 g (2/3 cup) granulated sugar and 50 g (1/4 cup packed) brown sugar until smooth, about 30 seconds. Add 180 g (3/4 cup) full-fat Greek yogurt, 1 large egg, and 1 tsp vanilla; whisk until combined.

Step 4: Bring dough together

Fold the dry ingredients into the wet mixture with a rubber spatula until just combined, about 20–30 strokes. Stir in 45 g (3 tbsp) chia seeds and 80 g (1/2 cup) chocolate chips if using. Do not overmix — stop as soon as no dry flour is visible.

Step 5: Portion the dough

Use a 1.5 tbsp cookie scoop or two spoons to drop dough 5 cm (2 inches) apart on prepared sheets. You should get about 24 mounds. Flatten each mound slightly with the back of a spoon for even baking.

Step 6: Bake until set

Bake in the preheated oven for 10–12 minutes, rotating pans after 6 minutes. Bake until edges are golden and centers look set but still soft, 175°C (350°F) internal cue not required. For a firmer cookie, add 1–2 minutes.

Step 7: Cool properly

Let cookies rest on the sheet for 5 minutes, then transfer to a cooling rack to cool completely. Cooling lets the interior finish setting and prevents breakage when you move them.

Expert Tips & Pro Techniques

Common mistake: Overbaking. Take cookies out when centers still look slightly underdone. They firm as they cool.
Use a digital scale for flour. Measuring by weight prevents dense, dry cookies.
Make-ahead: Store baked cookies in an airtight container at room temperature for up to 3 days. For prep, make dough, shape into logs, wrap, and refrigerate up to 48 hours; slice and bake fresh.
Professional trick for uniformity: Chill scooped dough for 10 minutes to reduce spreading if your kitchen is warm.
To boost chew without extra fat, swap 25 g (2 tbsp) granulated sugar for 25 g (2 tbsp) light corn syrup or honey. Reduce oven time by 1 minute if using honey.
To avoid flat cookies, measure baking powder fresh. Old leavening produces flat results.

Storage & Reheating

Refrigerator: Store cooled cookies in an airtight container for up to 5 days. Add a slice of bread to the container to preserve softness.
Freezer: Cookies freeze well for up to 3 months. Lay cooled cookies in a single layer on a tray, freeze 1 hour, then transfer to a sealed freezer bag with parchment between layers.
Reheating: Reheat in a 175°C (350°F) oven for 4–6 minutes from thawed, or 8–10 minutes from frozen. Avoid microwaving — it makes them gummy.

Variations & Substitutions

Gluten-Free Version: Replace 300 g (2 1/2 cups) all-purpose flour with 300 g (2 1/2 cups) 1:1 gluten-free blend (Bob’s Red Mill). Add 1/4 tsp xanthan gum if your blend lacks it. Bake time may increase by 1–2 minutes.
Egg-Free Version: Replace 1 large egg with 60 g (1/4 cup) applesauce and add 1/4 tsp baking soda. Texture will be slightly cakier.
Lower-Sugar Option: Reduce granulated sugar to 90 g (1/2 cup) and add 1–2 tbsp maple syrup for moisture. Watch closely during baking; centers may set faster.
Lemon-Chia Shortbread: Use 230 g (1 cup) unsalted butter, omit yogurt, add zest of 1 lemon and 1 tbsp lemon juice. Press dough into a pan and bake for a different cookie style. For a biscuit-style variation inspired by Greek yogurt biscuits, reduce sugar and flatten dough before baking.

Serving Suggestions & Pairings

Breakfast box: Pack two cookies with fresh berries and a hard-boiled egg for a balanced morning. See a quick yogurt pancake idea at fluffy Greek yogurt pancakes.
Tea time: Serve warm with a cup of Earl Grey or green tea. The tea’s brightness complements the yogurt tang.
Snack pairing: Spread a thin layer of chia jam and top with sliced banana. For a jam recipe, try chia seed jam.
Lunchbox upgrade: Pair with veggie sticks and a small container of hummus or nut butter for healthy variety. For frozen snack ideas, see frozen Greek yogurt peanut butter bites.

Frequently Asked Questions
Q: Why did my cookies turn out dry?
A: Dry cookies usually mean too much flour or overbaking. Weigh flour and remove from oven when centers look slightly underdone.

Q: Can I make this without eggs?
A: Yes. Replace 1 egg with 60 g (1/4 cup) applesauce and add 1/4 tsp baking soda to help lift. Expect a slightly cake-like texture.

Q: Can I double this recipe?
A: Yes. Double all ingredients and bake on separate sheets. Do not crowd the oven; bake in batches for even heat.

Q: Can I prepare the dough the night before?
A: Yes. Shape dough balls, cover tightly, and refrigerate up to 48 hours. Bake from cold, adding 1–2 minutes if needed.

Q: How long does this keep in the fridge?
A: Baked cookies keep in the fridge for up to 5 days in an airtight container. For longest freshness, freeze.

Q: Can I use flavored yogurt?
A: You can, but flavored yogurts add sugar and flavor. Use plain full-fat for the most control over sweetness and texture.

Q: Will the chia seeds change the bake time?
A: Chia seeds absorb some liquid but in this amount they don’t change bake time significantly. If you hydrate chia in liquid first, reduce yogurt by 1–2 tbsp.
