Skillet Protein Chocolate Chip Cookie Recipe

Why Make This Protein Skillet Cookie Recipe

There’s no reason why you shouldn’t make this protein pizookie! Check out all the reasons I love making this protein cookie skillet recipe!

• Easy clean-up: You just need to throw all your ingredients in a mixing bowl and then transfer the cookie dough to your baking pan. If you don’t have a cast iron skillet, you can use any oven-safe skillet. However, you won’t get the crispiness that comes from a cast iron pan.
• You dig right in: As soon as this skillet protein cookie is out of the oven, just add some whipped cream and grab a spoon! As I said earlier, it’s really hard for me to wait for the cookies to cool, so we’ll just dig right in!
• Molten chocolate chunks: This is so gooey and the chocolate chunks become absolutely incredible. That’s what I love about a cookie!
• Healthy ingredients: This is the best high protein chocolate chip cookie recipe! We’re making the dough with pumpkin puree, which is high in fiber and Vitamin C. We’ve also got protein powder for an extra boost of protein. If you’re eating this before bed, you won’t go to bed hungry! You’ll feel nice and satiated thanks to the protein powder.
• Fast to make: It’s ultra easy to make the batter and cook this. You can have this single serve protein cookie skillet for dessert at any time. No need to take lots of time out of your day to have a decadent treat!
• Roasted marshmallows: What really took this up a notch for me was the roasted marshmallows! This totally transforms it from your average skillet cookie. I love watching the marshmallows get roasted as the cookie bakes, and those marshmallows seriously add to the gooeyness of the cookie!

How to Make a Skillet Protein Chocolate Chip Cookie

This healthy cookie skillet is almost effortless! Here are the steps you need to follow:

1. Make your dough. Combine all ingredients except for your toppings in a large mixing bowl. Whisk well until you have a smooth dough.
2. Transfer dough to your cast iron skillet. Using a spatula, pour your cookie dough into your pan. You can also use a regular, oven-safe skillet if you don’t have a cast iron pan.
3. Add your toppings. Add the chocolate chunks and marshmallows on top. The marshmallows will roast in the oven.
4. Bake at 350 F. This will take 8-12 minutes, depending on how gooey you want your cookie.
5. Finish with whipped cream. Use any whipped cream of your choice to bring this skillet cookie all together, or make your own by following my recipe on How to Make the Best Whipped Cream at Home.

Tools Needed

• Large bowl
• Whisk
• Cast iron skillet
• Spatula
• Baking sheet

Ingredient Swaps & Substitutions

This skillet cookie is easy to make your own:

• No pumpkin puree? Mashed banana or unsweetened applesauce both keep it moist.
• Swap the protein powder for almond flour if you’d rather skip it (you’ll lose a little protein boost).
• Use any chocolate you’ve got — I love a mix of dark chocolate chunks and chocolate chips.
• Swirl a spoonful of peanut butter into the dough for extra richness.
• For a cakier texture, add a pinch more baking soda; for a denser, fudgier cookie, hold back slightly.

Tips for the Perfect Skillet Cookie

A few little things make a big difference:

• Whisk the wet and dry ingredients until just smooth — overmixing can make the cookie tough.
• Press the dough evenly into your skillet so it bakes through at the same rate.
• Around the 8-minute mark, pull it early for a gooey center or leave it the full 12 minutes for firmer edges.
• Don’t skip the toppings — a scoop of vanilla ice cream or a cloud of whipped cream takes it over the top.

Storage & Make-Ahead

This skillet cookie is best warm and fresh, but leftovers keep well! Cover the cooled skillet or transfer slices to an airtight container and store at room temperature for up to two days, or in the fridge for up to four. Warm a slice in the microwave for 10–15 seconds to bring back that just-baked, melty-chocolate magic.

Easy Swaps and Substitutions

Almost every ingredient here has an easy stand-in:

• Pumpkin puree becomes butternut squash or sweet potato puree.
• Cashew milk becomes oat or almond milk.
• Peanut butter becomes almond or sunflower seed butter.
• Coconut flour becomes almond or oat flour.
• Vanilla protein powder becomes vanilla whey protein isolate or vanilla collagen peptides.
• Spray oil becomes a little butter to grease the pan, and whipped cream becomes coconut cream or creme fraiche.
• Chocolate chunks become chocolate chips, whatever you have on hand.

Serving Ideas

This skillet cookie is made for sharing warm, straight from the pan:

• Grab two spoons and dig in while it is still gooey in the center.
• Add a scoop of vanilla ice cream for a protein pizookie.
• Finish with a drizzle of melted chocolate or an extra dollop of whipped cream.

Tips for the Best Protein Skillet Cookie

This protein skillet cookie comes together in one bowl and bakes in just 12 minutes. Whisk the dry ingredients — rolled oats, vanilla protein powder, coconut flour and baking powder — with the wet ingredients — pumpkin puree, cashew milk, brewed coffee and smooth peanut butter — until you have a smooth, thick batter. The pumpkin keeps it moist while the coffee deepens the chocolate flavor, and the coconut flour and protein powder give it structure without any regular flour. Grease your cast-iron skillet or oven-safe pan, spread the batter evenly with a spatula, then scatter over the mini marshmallows and chocolate chunks. Bake at 350°F for about 12 minutes, until it is set around the edges but still soft in the middle. Finish with a dollop of whipped cream and serve it warm, straight from the skillet.

There Is No Added Sugar in This Dough

Worth saying plainly, because it catches people out: there is no brown sugar, no coconut sugar, no regular sugar of any kind in this batter. The sweetness comes from the pumpkin puree and the vanilla protein powder, and then from the chocolate chunks and mini marshmallows that go on before it bakes. That is a large part of why it works as a single-serving dessert that does not flatten you afterwards.

If you want it sweeter, you have easy options rather than a rewrite. A drizzle of maple syrup over the finished cookie is the simplest. A tablespoon of coconut sugar or brown sugar whisked in with the wet ingredients will do it too, although it will brown faster in the oven, so start checking at around ten minutes instead of twelve. A quarter teaspoon of cinnamon in the dry ingredients makes the whole thing read sweeter without adding anything at all.
