Ingredients In This Recipe
The printable recipe further down the page has the complete list of ingredients, including quantities and step-by-step instructions.
Cake mix - We used Betty Crocker's super moist red velvet cake mix. The boxed weight was 480 grams (1.05 pounds, 16.93 ounces) and came with a pre-made frosting (icing) mix.
Vegetable oil - or use another light-flavored oil.
Eggs - We used large eggs with an average weight of 56 grams (1.9 ounces).
White chocolate chips - these make a lovely contrast against a background of red.
Frosting topping (optional) - If your boxed cake mix has a frosting use it to frost the top of the brownies.
If not, use a store-bought or homemade frosting for the topping, or don't frost.
Equipment
- Parchment paper to line the tin or nonstick cooking spray
- 20cm (8 inches) square cake tin or baking dish
Step By Step Instructions
How to make red velvet brownies with cake mix:
Preheat oven to 170°C (350°F). Grease or line the base and sides of 20cm (8 inches) square cake tin or baking dish with parchment paper.
Step 1 - All you need to do is place the cake mix into a mixing bowl with the eggs, oil, and a cup of chocolate chips.
Step 2 - Use a wooden spoon or spatula to mix until well combined.
Step 3 - Transfer the batter to the prepared tin, and use a metal spoon to spread it evenly in the cake tin. Bake for 20-25 minutes or until the edges are slightly brown and the middle has just set and is no longer wet.
Step 4 - Remove from the oven and place the tin on a wire rack. Leave the brownie to cool completely in the cake tin.
Step 5 - Remove from the tin, spread on the frosting, decorate it with sprinkles, and cut it into pieces.
Recipe Notes
Cake mix
Not every cake mix weighs the same. The one we used came with a packet of frosting. The boxed weight was 480 grams (1.05 pounds, 16.93 ounces) and serves 12.
- The dry cake mix packet weighed 365 grams (12.80 ounces)
- The icing mix weighed 123 grams (4.35 ounces)
You only need the dry cake mix to make the brownies.
Frosting
Use frosting that comes in the box. If it is not already mixed, make the frosting as instructed on the packet and frost the cold brownie slab before cutting.
Or, if the cake mix does not come with frosting, use a store-bought or homemade vanilla cream cheese frosting.
Recipe Tips
Tin size
Use a square 20cm (8 inches) cake tin or baking dish and line it with parchment paper, so you can easily lift the brownie slab from the cake tin.
About the batter
The batter is thicker than you would get from making a cake from the boxed mix, but this is what you want because brownies are dense and not as light as cakes.
Spreading the batter
If you find it hard to spread the batter, dip a metal spoon in hot water and wipe it dry to make spreading the brownie batter easier.
Serving Size
This recipe makes 12 red velvet brownies, and one piece is a serving size.
Calories Per Serve
There are about 251 calories per serve and includes the frosting.
Variations
Make different flavors - You can use other cake mixes to make brownies like these strawberry cake mix brownies or this chocolate chip brownies and more.
Storage
Refrigeration – These cake box brownies can be stored once cooled in an airtight container for two to three days at room temperature.
Freezing – These can be frozen. Freeze in one big slab that can be cut into pieces when defrosted, which is great for parties.
You could also cut it into individual servings, freeze them in a single layer on a baking tray, and once they have frozen transfer them to a freezer-safe bag or airtight container.
Or individually wrap the pieces in plastic for quick and easy lunch box treats.
