Easy Gluten Free Protein Skillet Brookie Recipe

If you have ever wanted a warm, fudgy brownie and a gooey monster cookie in the same bite, this protein skillet brookie is exactly what you have been missing. It is a two-layer cast iron skillet dessert with my viral scoopable protein monster cookie on the bottom and a rich, chocolatey brownie layer on top, baked until the edges are set and the center is still soft like a lava cake. Scoop it into bowls, add a big spoonful of vanilla protein ice cream, and you have the kind of shareable treat that disappears fast.

This is a high protein dessert that actually delivers on flavor and texture. I use TruEats gluten free brownie mix for the brownie layer because it is made with clean ingredients, no artificial sweeteners, no filler starches, and it bakes up with an incredible fudgy texture. One scoop of Equip Foods chocolate protein powder goes right into the brownie batter for extra protein without changing the chocolate flavor you want. It's the perfect healthy dessert to make any time your sweet tooth needs satisfying!

Why You'll Love This Recipe

It is two desserts in one. Cookie dough on the bottom, fudgy brownie on top. Every scoop has both layers.

The texture is unreal. The edges are set, the center is warm and molten, and it scoops like a dream straight from the cast-iron skillet.

It is beginner friendly. If you can stir two batches of batter and layer them in a skillet, you can make this. No mixer needed.

The brownie mix is artificial sweetener free. TruEats uses monk fruit, which means you get a sweet, rich chocolate flavor without the aftertaste that comes from artificial sweeteners. It is a great artificial sweetener-free option for anyone who is sensitive to those ingredients.

Ingredients & Tested Substitutions

See the full ingredient list and instructions in my scoopable protein monster cookie recipe. Here is a quick overview of what makes it work:

Almond flour. Keeps the cookie layer tender and gluten free. If you need a nut-free version, oat flour works as a swap.

Seed butter or nut butter. Tahini, sunflower seed butter, or very drippy almond butter all create that gooey, soft cookie texture. If peanut butter is your go-to, that works too. Use whatever you keep in your curated pantry.

Maple syrup. Sweetens the cookie layer naturally, no refined sugar needed.

Unflavored protein powder. I use Equip unflavored protein (use code PRETTYDELISH for a discount) because it has clean ingredients and does not compete with the cookie flavor.

Chocolate chips. Dark chocolate chips are my preference here. They melt into the cookie layer and add pools of chocolate in every bite.

For the Brownie Layer

TruEats gluten free brownie mix. This is the star of the brownie layer. It is made with a blend of chickpea flour, almond flour, buckwheat flour, and other whole food ingredients, sweetened with monk fruit and erythritol, and it bakes up with a deeply fudgy texture. No artificial sweeteners, no filler starches, no junk. You can find it at here on Amazon..

1 large egg. Binds the batter and helps the brownie set properly.

½ cup avocado oil. Avocado oil is one of my preferred cooking fats and oils for baking because it is neutral in flavor and performs well at higher temperatures. Don't use olive oil, you will be able to taste it!

¾ cup water or brewed coffee. Water works great, but if you want a stronger, deeper chocolate flavor, use brewed coffee instead. It does not make the brookie taste like coffee, it just amplifies the unsweetened cocoa powder notes already in the mix.

1 scoop Equip Foods chocolate protein powder. Stirs right into the brownie batter with the wet ingredients and dry ingredients. Use code PRETTYDELISH at equipfoods.com for a discount.

Optional add ins: unsweetened chocolate chips & pure vanilla extract to enhance the chocolate flavor.

Protein Skillet Brookie Step by Step Instructions

1. Preheat your oven to 350F.

2. Prepare the cookie layer. Make the scoopable protein monster cookie dough according to the recipe. Set aside.

3. Prepare the brownie batter. In a medium bowl, whisk together the large egg, avocado oil, and water or coffee. Add the TruEats brownie mix and one scoop of Equip chocolate protein powder. Stir until the dry ingredients are fully incorporated and no dry pockets remain. Do not overmix.

4. Layer the skillet. Lightly grease an 8 to 12-inch cast iron skillet. Scoop the cookie dough into the skillet first and spread it into an even layer using the back of a spatula or your hands. Then pour the prepared brownie batter directly on top of the cookie layer.

5. Bake for 20 to 25 minutes, until the top of the brownie layer is set but the center is still soft when you gently press it. You want that lava cake center, not a fully baked-through brownie. Start checking at 20 minutes.

6. Let it rest for 5 minutes, then scoop straight from the skillet into bowls. Top with a big scoop of dairy-free vanilla protein ice cream and serve immediately.

Expert Tips & Tricks

Do not skip the rest time. Even 5 minutes out of the oven makes a difference. The brookie will hold its layers better when scooped and the center will settle into that perfect fudgy texture.

Use coffee in the brownie batter if you can. It does not add a coffee flavor, it just makes the chocolate deeper and richer. This is one of those small tweaks that makes a big difference in the final chocolate flavor.

Room temperature egg is best. A room temperature egg blends more smoothly into the brownie batter and helps create a more even texture throughout. Pull it out of the fridge when you start gathering your ingredients.

Cast iron is the right pan for this. A cast-iron skillet distributes heat evenly throughout the protein brownie skillet and gives you those slightly crisp edges with a soft, gooey center. You can use a standard oven-safe skillet if you do not have cast iron, but the results are best in a cast iron skillet.

Do not overbake. The top should look just set and the center should still have a slight jiggle when you pull it. The brookie will continue to cook slightly from residual heat. Overbaking is the fastest way to lose that lava cake texture.

Can I make this vegan? You sure can! Swap in your favorite vegan protein powder, a flax egg and follow the package instructions to make vegan skillet brownies for the top layer. Some people use unsweetened applesauce as an egg replacer, but I have not tested that in this recipe.

Serving Ideas

This skillet protein brownie is best served warm, straight from the cast-iron skillet, scooped into bowls. Here is how I like to serve it:

With vanilla protein ice cream. My dairy-free vanilla protein ice cream made in the Ninja Creami melts into the warm brookie and makes this the perfect high protein dessert. It also makes this a genuinely free vanilla ice cream option if you make it dairy-free.

As a shareable treat. This skillet serves 6 and it is the kind of dessert you bring to the table and let people scoop themselves. It is a natural conversation starter and the kind of thing people genuinely get excited about.

With a drizzle of almond butter. If you want to lean into that chocolate-nut butter combination, a thin drizzle of warm almond butter over the top right before serving is really good.

How to Store Protein Skillet Brookie

This brookie is best eaten warm on the day it is made. If you have leftovers, let it cool completely and store it covered tightly at room temperature or in a tight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 30 to 45 seconds until warm and soft again.

FAQs

Can I use a different protein powder? Yes, as long as it is a chocolate flavored protein powder you enjoy eating. The Equip chocolate protein powder blends particularly well here because it has a clean ingredient list and real chocolate flavor, but another chocolate protein powder you trust should work. Avoid vanilla protein in the brownie layer since it will compete with the chocolate flavor.

Can I make this without the cookie layer? You can, but then it is just a skillet brownie. The brookie is the whole point here. The monster cookie layer adds texture, extra protein, and that cookie-and-brownie combination that makes this worth making.

What size cast iron skillet do I need? Anywhere from 8 to 12 inches works. A smaller skillet will give you a thicker, more molten center. A larger skillet will spread things out more and cook faster. Start checking for doneness at 20 minutes regardless of skillet size.

Can I make this dairy free? Yes. The TruEats brownie mix is dairy free, Equip protein powder is dairy free, and the cookie layer can be made dairy free as well. Just use dairy free chocolate chips and a dairy-free ice cream on top. My vanilla protein ice cream is already dairy free.

Is this low carb? This is not a low carb skillet brownie. The brownie mix and the cookie layer both contain natural carbohydrates. If you are specifically looking for a low carb skillet brownie, you could experiment with a from-scratch recipe using only almond flour and a low carb sweetener, but that is a different recipe entirely. This one prioritizes real food ingredients and great flavor.

Can I add mix-ins to the brownie layer? Dark chocolate chips or coconut butter chips scattered over the top before baking are a great addition. They melt into the brownie layer as it bakes and add extra richness.
