    These Cookies and Cream Brownies take my eggless brownies to the next level! They have gluten free/vegan chocolate sandwich cookies inside the brownies themselves. They are then topped with cookies and cream buttercream, chocolate ganache and then more cookies and cream cookies! They’re unbelievable! Best part is they’re gluten free, nut free, egg free and can easily be vegan! 

    Cut up rectangular portions of Vegan Cookies & Cream Brownies.

    If you love brownies and cookies and cream…this Cookies and Cream Brownies recipe is for you!!!! This eggless brownies recipe isn't dry or cakey; the brownies taste just as they should; chewy, gooey and fudgy! The batter mixes up in one bowl with a whisk; no mixer is needed! Add that with cookies and cream, the end result is nothing less than magical! I was inspired by Sally's Baking Addiction’s Cookies and Cream Brownies.

    • Cookies and Cream Brownies

    Reasons to Love These Brownies

    • Allergy Friendly- These brownies are gluten free, nut free, egg free and can easily be dairy free (vegan)!
    • Fudgy- These brownies are not cake like. They're fudgy and gooey! 
    • Double The Chocolate- There is cocoa powder and melted chocolate in these!
    • Cookies & Cream- There are loaded with chocolate sandwich cookies, topped with cookies and cream frosting and then decorated with even more sandwich cookies!

    Ingredient Notes

    Confectioners' sugar, cocoa powder, granulated sugar, baking chocolate, gluten free flour, white vinegar, butter, cornstarch water, baking powder, kosher salt, vanilla, milk, vegetable oil, water, chocolate sandwich cookies in separate containers.
    • Gluten Free Flour-If you also have nut allergies, make sure to use a brand that’s made in a nut free facility.  I really love to use this gluten free flour because it’s nut safe but it does contain dairy. It also contains xanthan gum which really helps give baked goods their bounce.
      Cornstarch and Water- These are eggless brownies so this mixture helps bind everything together.
    • Butter/ Vegan Baking Stick- You can use either.
    • Vegetable Oil- I use this for added moisture. 
    • Milk- If there are no dairy allergies or if you’re not vegan, you can use regular whole milk. For non dairy, use a non dairy milk of your choosing. 
    • Cocoa Powders- I like to use two types but if you only want to use one, use Dutch or Natural Unsweetened.
    • Chocolate- For the melted chocolate in the batter, make sure to use gluten free/nut free and vegan if you want these dairy free. It must be baking chocolate, not chocolate chips.
    • Chocolate Sandwich Cookies- There are a lot of these cookies in these brownies. 16 in the inside of the brownies, 6 in the buttercream and 3 for the topping. You could of course use less…but I think this is the perfect amount! I use these gluten free/vegan chocolate sandwich cookies.

    See my recipe card below for a complete list of the ingredients with measurements.

    Substitutions and Variations

    How to Make these Vegan

    • Use a gluten free flour that’s free from dairy.
    • Make sure the brand of sugar you use is vegan. 
    • Use vegan baking sticks instead of butter.
    • Make sure to use a non dairy milk.
    • Only use vegan baking chocolate.
    • Make sure to use vegan/gluten free chocolate sandwich cookies.
    • Use vegan chocolate chips for the ganache.

    How to Make this recipe with All Purpose Flour

    • Use 1 ¼ cups packed AP flour (210 grams).
    • Make sure to use 5 tablespoons packed cocoa powder.

    This recipe has not been tested with these substitutions and/or variations due to celiac disease and food allergies. If you change any of the ingredients, please let us know how the recipe turned out in the comments below!

    How to make Cookies and Cream Brownies

    Here are the step by step instructions to make these brownies!

    Step 1: Preheat the Oven and Line the Pan with Parchment Paper

    Preheat the oven to 350 degrees and line an 8 x 8 inch baking pan with parchment paper. Make it long enough so there is about a ½ overhang on each side so that you can lift the brownies out easily once they have cooled. Do not grease.There is enough oil in the brownies that greasing would be too much.

    Step 2: Heat the Chocolate

    Chop all the chocolate into tiny pieces. Place the chopped chocolate in a microwave safe bowl. Add the butter and vegetable oil to the bowl. 

    Heat in 15 second increments and stir after each time. Repeat until the chocolate is completely melted and silky smooth. Set aside.

    Mixing in butter in the bowl.

    Step 3: Make the Homemade Buttermilk

    In a small bowl, combine the milk and white vinegar. Let sit 5-10 minutes and stir again. It will appear chunky. That's normal. Set aside. 

    Step 4: Make the Cornstarch Water

    In a small bowl, using a spoon, mix together the cornstarch and water until thin and watery. It will be thick and tacky at first.

    Step 5: Whisk in the Cornstarch Water

    Into the melted chocolate and butter, mix in the cornstarch water until fully combined. 

    Step 6: Whisk in the Sugar, Vanilla, Baking Powder, Salt and Milk

    Into the chocolate mixture, whisk in the sugar, vanilla, baking powder and salt until combined.

    Then whisk in the milk vinegar mixture until combined and smooth.

    Adding in the homemade buttermilk into the bowl.

    Step 6- All combined

    Step 7: Add in the Cocoa Powder and Flour

    Using a spatula, mix in the cocoa powder and flour. Stir until everything is just mixed together and combined. The batter will be super thick and sticky.

    Step 7- Part 2

    Step 8: Scoop the Batter into the Pan and Add Cookies

    Spoon half the batter into your baking dish and use your hands to press it down into the shape of the pan. You should end up with a smooth even layer of batter. 

    Gently press 16 gluten free/vegan chocolate sandwich cookies into the batter.

    Then take the other half of the batter and press it on top of the chocolate sandwich cookies, covering all of them. You should end up with a smooth even layer of batter.

    Step 9: Bake and Let Cool

    Bake the brownies in the center rack of the oven at 350 degrees Fahrenheit for 40 minutes. 

    Let the brownies cool completely before frosting.

    Step 9

    Step 10: Make the Frosting

    While the brownies are baking, make the frosting. In the large bowl of an electric mixer or using a hand held mixer, beat the butter or vegan baking stick until smooth and creamy. About 2 minutes.

    With the mixer on very low speed, slowly add in the confectioners' sugar. Add in the vanilla and beat until combined. While the mixer is on, slowly add in the water a little at a time until you get the desired consistency. You may not need to use all the water.

    Using a spatula, gently fold in the 6 broken chocolate sandwich cookies until just combined. If you overmix them the frosting will become grey instead of white.

    Step 11: Frost the Brownies and Chill

    Once the brownies have completely cooled, keep them in the pan and frost the top completely with all of the buttercream frosting.

    Pop the brownies (still in the pan) in the fridge for at least 15-20 minutes. You want the frosting layer to become hard for the next step.

    Vanilla buttercream with chocolate sandwich cookies is added to the top of the brownie.
    The frosting is smoothed evenly across the brownie.

    Step 12: Make the Ganache

    When the brownies are ready to come out of the fridge, make the ganache. Place the chocolate chips and the butter or vegan baking stick in a microwave safe bowl. Heat in 15 second increments, stirring after each time, until the melted and silky smooth.

    Slices of butter and chocolate chips in a bowl.
    Warm smooth chocolate ganache with a spoon.

    Step 13: Pour on the Ganache

    Take the brownies out of the fridge, and pour the liquid ganache on top of the frosting while still in the pan. Quickly break up 3 more chocolate sandwich cookies and scatter them over the top of the brownies while gently pressing them into the ganache so they stick. Pop the brownies back in the fridge until the ganache hardens.

    Chocolate ganache is poured atop the frosting.
    The chocolate ganache is spread evenly and smooth on top.
    Adding a layer of sandwich cookie in the brownie batter.

    Step 14: Serve

    Thaw the brownies on the counter for at least 10 minutes prior to cutting. Lift the brownies out of the pan using the parchment overhang and slice the brownies into big squares, tiny squares, large rectangles or small rectangles...whatever your heart desires.

    Store them in an airtight container at room temperature. If you store them in the fridge they get rock hard and will break your teeth! There is no heavy cream in this ganache so you can leave them airtight at room temp. Enjoy!

    Expert Baking Tips

    • Use 2 Types of Cocoa Powder- The 2 types of cocoa powders give the brownies their dark hue. If you only have one type on hand, use natural unsweetened or dutch...just know their color will not be as dark as mine. Do not use dark alone; it will make your brownies too chalky, dry and bitter.
    • Only Use Chocolate Bars- Don’t try to use melted chocolate chips inside the brownies. If you use chocolate chips, the brownies bubble and boil and never set if you do. I learned this the hard way. I know it can be difficult to find chocolate that is made in a nut free facility and is also dairy free. The brand Enjoy Life makes vegan/gluten free chocolate bars.
    • Melt the Chocolate and Butter, Slowly- If you rush this process and try to even heat the chocolate in 20 second increments (instead of 15 second increments), you can overheat the chocolate. If that happens it will seize up and basically not be usable.
    • Use Your Hands- The batter to the brownies itself is so super thick that it appears almost as though it is a cookie dough. Press the batter into your lined baking pan. You should end up with a smoother layer of batter, aside from some fingerprints.
    • Let Them Cool- When the brownies come out of the oven, allow the brownies to cool completely before adding the frosting. If you try to add the frosting when they're warm, it will turn into a liquidy mess.
    • Chill the Brownies- Once you frost them, chill the brownies for at least 20 min. You want the frosting layer to be cold and hard for when you add the ganache.

    Recipe FAQs

    Can these brownies be made ahead of time?


    Yes, you can make these brownies the day before.

    Can this recipe make less brownies?


    If you're looking for less, try my Small Batch Brownies!

    Can I use melted chocolate chips in the brownies?


    No. You must use baking chocolate. I have tried this so many times and the brownies would bubble, boil and never set. I never knew that you needed to only use baking chocolate when trying to make eggless brownies until I found the lovely Rachael of Sugared & Stirred's Vegan Classic Brownie Recipe! She talked about this happening to her too and that baking chocolate vs chocolate chips was the answer!

    How do I store these Cookies and Cream Brownies?


    Keep the extra brownies in an airtight container at room temperature. If you don’t have an airtight container that fits them all, wrap any extras in aluminum foil for up to 2 days.

    If storing in the fridge, leave the brownies out for 1-2 hours prior to eating to bring to room temperature otherwise they will be rock hard and break your teeth. Do not eat them cold!

    If desired, warm each brownie in the microwave for 5-10 seconds prior to eating; be careful not to burn your mouth.

        Hi there! It's for one. It is a computer generated estimate. Also I cut them very large to only get 12. If you cut them into more...like 16-20, the calories will be much less. Also...if you're looking for a lighter option, you can check out my regular brownie recipe. They're only 228 calorie each.
