• Nonfat Greek yogurt – Boosts protein and keeps the cookie dough moist.
• Pure maple syrup – Just enough natural sweetness.
• Oat flour – A simple flour option that keeps the texture soft and tender.

How to make a healthy chocolate chip cookie skillet for one

Step 1: Preheat your oven to 350 degrees F and lightly grease a small cast-iron skillet or oven-safe dish with melted coconut oil, avocado oil, or melted butter.

Step 2: In a small bowl, combine the egg yolk, cashew butter, Greek yogurt, and maple syrup. Mix the wet ingredients, then stir in the dry ingredients (oat flour, protein powder, and baking powder). Mix until a runny cookie dough forms.

Step 3: Stir in half of the chopped dark chocolate.

Step 4: Transfer the batter to your prepared skillet and spread it evenly. Top with the remaining chocolate chunks.

Step 5: Bake for 6-7 minutes, until the edges are set but the center stays soft and gooey. Let it cool slightly, then enjoy it warm!

Pro tips

• Don’t overbake – The gooey center is the best part
• Use a high-quality whey protein – This makes a big difference in texture
• Grease your skillet well – Prevents sticking and helps crisp the edges
• Let it rest for 1-2 minutes – It firms up slightly after baking

Serving ideas

• Enjoy straight from the skillet while warm (the beeeeest!!)
• Top with a scoop of vanilla ice cream or Greek yogurt for even more protein
• Add a sprinkle of flaky sea salt
• Drizzle with peanut butter or melted chocolate

Substitutions, optional variations & dietary adjustments

Below you’ll find a list of substitutions that will work well in this protein skillet cookie recipe. 

If you try something different out, please leave a comment below letting us all know how it turned out!

Cashew butter – You can substitute any nut butter here depending on what you have on hand. Almond butter works great for a more neutral flavor, while peanut butter gives it a richer, classic cookie taste. Sunflower seed butter is also a great nut-free option.

Oat flour – Oat flour keeps the texture soft and tender, but almond flour can be used for a slightly softer, more rich texture. You can also make your own oat flour by blending rolled oats in a blender until fine.

Maple syrup – A little pure maple syrup adds sweetness and flavor, but honey or coconut sugar works just as well. You could also use a sugar-free syrup if you want to lower the added sugar.

Greek yogurt – Nonfat Greek yogurt adds moisture and extra protein. You can swap in a dairy-free yogurt if needed, or use a whole milk greek yogurt for a richer texture.

Whey protein powder – A vanilla whey protein powder gives the best soft and gooey cookie texture. Plant-based protein powder can work too, though the skillet cookie may turn out slightly more dense or cakey.

Dark chocolate – Chopped dark chocolate gives you those melty pools of chocolate throughout the cookie skillet, but chocolate chips or chocolate chunks work perfectly too. Milk chocolate or semi-sweet chocolate can also be used if you prefer a sweeter dessert. For a nutty addition, try adding some chopped pecans or walnuts.
