It is SO EASY to make Red Velvet Brownies from a cake mix! You wouldn’t think a fluffy cake could turn into chewy, fudgy brownies, but it is quick and delicious.
I love using pantry ingredients for desserts. This way you always have something yummy on hand that you just need to mix and bake. Cake mix isn’t just for cake (or brownies!) – you can easily turn a cake mix into an amazing peach cobbler. Another fun classic is making Funfetti Cookies – the kids will love these colorful cookies.

- It uses a few ingredients: With only 5 ingredients, this recipe uses standard baking items you likely always have on hand.
- Make-ahead recipe: Brownies freeze beautifully and retain their texture when thawed, so you can make these well in advance.
- Customize your favorite: Swap out the chocolate or extract to make a new combo you’ll fall in love with.
🧾 Ingredients Needed
I’ve highlighted a couple of ingredients below with some relevant notes. Aside from this, the ingredients needed are pretty basic.
- Cake mix – Look for a standard red velvet cake mix from a brand you enjoy eating.
- Eggs – Room temperature eggs will mix in the best.
- Butter – I usually grab unsalted when baking, but the difference is negligible so use whatever you have on hand.
- Vanilla – A classic flavor to amp up the cake mix.
- White Chocolate Chips – The bright white really pops against the pretty red brownies.
You can easily mix things up here! Whether you don’t want to go to the store and need to use what you have, or you ARE at the store and see a new flavor of cake, grab it and go.
- Mint Chocolate – Try Devil’s Food for super dark brownies, and add in mint extract with chopped candy canes. (Or we use a brownie mix for these mint brownies.)
- Autumn Fun – Grab a spice cake mix plus cinnamon baking chips.
- Plain Jane Vanilla – Nothing’s boring about classic vanilla when mixed with dark chocolate chips.
- PB Chocolate – Chocolate cake plus peanut butter chips? Yes, please! Chocolate peanut butter brownies are hard to beat!
- Frosting – Another great option is to stir in all the white chocolate, then top with your favorite cream cheese frosting once cooled.
👩🏻🍳 How to Make Cake Mix Red Velvet Brownies
Line your baking dish with parchment paper, making sure to leave an overhang. This is key to removing the entire pan of brownies for easy slicing. Preheat the oven before beginning.
*Be sure to see the recipe card below for the full ingredients list & instructions!*
STEP 1. Mix it up. Add all ingredients except the chocolate chips to a large mixing bowl (Image 1).
Tip: Make sure you let your melted butter cool down before adding to the mix. You don’t want it to cook your eggs!
STEP 2. Combine well. Mix well until fully combined. (Image 2). This is a super thick batter and you want it to be smooth and all one color.
STEP 3. Chips and bits. Add in all but a handful of chips and stir to combine (Image 3).
STEP 4. Spread and top. Spread the thick batter in the prepared baking pan and smooth over the top. Add the remaining chips on top (Image 4).
STEP 5. Bake. Bake until the top is no longer shiny and wet. You can check with a thermometer. Let cool before slicing.
💭 Recipe Pro Tips
- Line your pan. It’s much easier to cut neat brownies outside of the pan – and the best way to achieve that is with a paper sling to lift the brownies out.
- Correct temperature. Make sure your butter and eggs are at room temperature. If the butter is too hot the eggs are in peril and if the eggs are too cold, they don’t mix in as well.
📋 Recipe FAQs
It’s not completely necessary, but it makes for a better presentation. To ensure they won’t stick in the pan, I prefer to line with parchment and leave an overhang to remove the entire baked tray at once. This will make for easier cutting on a cutting board! If you prefer, you can grease the pan really well and slice in the pan.
Dense or fudgy brownies often contain more fat and almost always start with melted butter for proper texture. Some recipes might even add an extra egg yolk to the whole egg. If you prefer lighter brownies that are more like cake, these will generally have a bit more flour than dense brownies, and oftentimes baking powder is added.
Cake mix contains more leavening agents, to ensure the texture is light and fluffy. However, we are using fewer eggs than the box calls for when making cake, which counteracts some of that action. This gives us the best fudgy texture we want!
- Countertop. Once the brownies have cooled completely, cover the baking dish with plastic wrap or slice the brownies and transfer them to an airtight container. Store them on the counter for up to 4 days.
- Refrigerator. If you want your brownies to last a little longer, allow them to cool to room temperature before slicing them into squares. Transfer the brownies to an airtight container and store them in the fridge for up to 1 week.
- Freezer. Wrap each individual brownie in a layer of plastic wrap followed by a layer of aluminum foil. Seal the brownies in a large Ziplock bag and store them in the freezer for up to 3 months. Allow the brownies to thaw at room temperature before diving in.

- 1 box red velvet cake mix
- 2 teaspoons vanilla extract
- 2 eggs room temperature
- ½ cup butter melted and cooled
- 1 ½ cups white chocolate chips
- Prep. Preheat the oven to 350 degrees F and line an 8 X 8-inch baking dish with parchment paper. Alternatively, ditch the parchment paper and opt for non-stick cooking spray instead.
- Make the batter. Mix together the cake mix, vanilla, eggs, and butter. Once that’s combined well and smooth. fold in all but a handful of the white chocolate chips. The batter will be thick.
- Bake. Smooth the batter into the prepared baking dish. The batter is very thick so you'll need to smooth it out to the corners and then smooth the top. Bake it uncovered for 25 minutes.
- Check to make sure it's done with a thermometer inserted into the center of the dish, if it has reached 165 degrees f they are baked! If you like your brownies a bit more done you can bake another 5 minutes. Once out of the oven, while still hot, sprinkle the remaining hand full of white chocolate chips over the top.
- Cool. Allow the brownies to cool in the baking dish before slicing and serving.
- Always line your pan for easy removal!
- Make sure your eggs are room temp for easy mixing.
