Best Fudgy Cake Mix Brownies
Brownies are my go-to dessert when a chocolate craving hits. Give me cosmic brownies, German chocolate brownies, or Oreo brownies and I’m in heaven!
While brownies from scratch are fantastic they take more time. Cake mix brownies are one of the easiest desserts and all you need is a box of chocolate cake mix!
I will show you how to make delicious fudgy brownies from a cake mix and once you learn this easy shortcut, you’ll always keep a boxed mix on hand to make chocolate dump cake or brownie mix cookies!
Recipe Ingredients
This cake mix brownie recipe only has 4 ingredients which is part of the reason why they’re so easy to make!
Find the full printable recipe with specific measurements below.
- Box devil’s food cake mix: Devil’s food flavor is darker than regular chocolate cake, but use whatever chocolate cake mix you have in your pantry.
- Salted butter: I use melted salted butter for its rich and delicious flavor, plus the salty butter balances the chocolate. If using unsalted, add a pinch of salt. The melted butter also helps to give the brownies a chewy, fudgy texture.
- Large eggs: If you’re baking a cake from a box, you’ll usually add 3 eggs, but we don’t want to make super cakey brownies, so I’ve reduced the number of eggs to 2.
- Chocolate chips: Adding semi-sweet chocolate chips gives brownies from cake mix a fudgier texture.
Substitutions and Variations
I’m giving you the basic recipe, but go ahead and customize these cake mix brownies to your own preferences. This recipe will work with different cake flavors and mix-ins.
- M&M: Mix in 1 cup M&M’s or do half chocolate chips.
- Different chips: Think toffee bits, peanut butter chips, or butterscotch chips.
- Nuts: Add about 1/2 cup of chopped walnuts, peanuts, or pecans.
- Oreo: Add half the batter and press a layer of Oreos then spread the remaining batter on top.
- Caramel: Add a layer of melted caramel as I do with my fudge caramel brownies
- Red velvet: Use a red velvet mix to make red velvet brownies and swap out chocolate chips for white chocolate chips. I also like making red velvet cake mix cookies.
- Blondies: Use a mix of yellow cake to make blondies.
How to Make Brownies from Cake Mix
This is a fool-proof one-bowl recipe that you can make in a matter of minutes. Grab a bowl and spoon and let me show you how making brownies from chocolate cake mix is done.
- Mix. Line a 9×9″ or 8×12″ pan with parchment paper. Whisk the eggs then pour the cake mix and melted butter on top and stir together lightly until just combined. Over mixing the dough can result in dry brownies. Stir in chocolate chips.
- Spread the dough. Press the thick brownie batter dough into the prepared pan until it covers the surface. Sprinkle on a few extra chocolate chips if you want your brownies to be extra chocolatey.
- Bake. Bake brownies at 350°F until a toothpick comes out clean. Keep an eye on them as they are baking as you don’t want them to brown.
- Cool. Remove from the oven and let your cake mix brownies cool for 15 minutes then remove them from the pan and slice them into 12 squares.
Expert Tips
- You can use a glass baking dish or metal baking pan to bake your cake mix brownies. Metal pans will give you slightly crispier edges.
- Lightly spray your hands or a rubber spatula with cooking spray to help spread the thick batter over the pan.
- Avoid over baking cake mix brownies by checking them before the finish time. They should look baked around the edges with the center looking slightly undone. They’ll continue to bake from residual heat in the pan after removing from the oven.
- Let the brownies cool completely before slicing them into squares. Running your knife under hot water before making the slices will give you cleaner edges.
Serving Suggestions
I’m all for enjoying these rich, chocolatey, and chewy brownies from cake mix as is, but they’re also amazing when they’re dressed up!
Top them with a scoop of vanilla ice cream and a drizzle of hot fudge sauce and you have yourself a mouth-watering dessert! I’ve also served them with a dollop of whipped cream and some homemade caramel sauce as a sweet end to dinner. Delicious!
Do you like your brownies frosted? Try spreading on some chocolate buttercream or caramel cream cheese frosting to make them just a bit more decadent.
Recipe FAQs
Both mixes contain flour, flavor, and sweetener. Cake mix contains more leavening agent than brownie mix, so the cake will rise up more, but in this recipe, we reduce the number of eggs required for making a cake to help counteract the rise.
Using oil makes brownies fudgier while butter adds a richer flavor and gives them a touch more cakey texture. Because we add chocolate chips though, these brownies from a cake mix still turn out fudgy even when using butter!
Absolutely! Chocolate brownies are the traditional flavor, but you can follow this recipe using your favorite cake flavor. I use strawberry cake mix to make strawberry brownies!
Yes, you can also store them in an airtight container or freezer bag in the freezer for up to 3 months. Once you’re ready to serve them, remove them from the freezer and thaw them at room temperature.
I also like to warm them up for a few seconds in the microwave. It makes the middle even fudgier!
Storing
Store your cake mix brownies in a covered container to lock in the moisture. If you leave them exposed they’ll dry out too quickly. Keep them for up to 3 days at room temperature.
It’s best not to refrigerate your cake mix brownies. Storing them in the fridge can dry them out and they’ll become hard.

It doesn’t get much easier than these! The kids loved them, the perfect snow day treat!
They turned out rich, fudgy, and chewy. I added caramel on some and that was really good! Thanks for sharing.
I’m so glad you enjoyed the brownies Nessa :)
Followed the recipe almost exactly (added a bit of oil to moisten it up) and it definitely turned out more cake-like than brownie. Good flavor, but I feel like I need to add frosting to really enjoy it.
I’ll give it 5 stars because it’s chocolate. I made this, it’s cooling now. Baked 24 minutes. Doesn’t look dry around the edges. Added chopped walnuts and 2 capfuls of vanilla. Will make again.
Great simple easy brownie hack! I cooked a little too long (24 min) so it was dry around the edges, but would make again.
I am so glad that you loved the simplicity of these brownies!
