Why I love these strawberry brownies made with cake mix:

  • Only 4 basic ingredients (not counting the glaze). Grab a strawberry cake mix and you’re set! You probably have all of the other ingredients in your pantry right now!
  • One bowl. Aside from making a flax egg in a separate bowl (to keep these vegan), the ingredients get stirred all together at the same time in one bowl. Super easy!
  • Customizable. Not in the mood for strawberry? Get creative with this recipe! You can try regular chocolate brownies or even lemon bars. Scroll down for more flavor options.
  • Flavorful. Even though these brownies are semi-homemade, they have the most wonderful strawberry flavor. They also have such a great texture and everyone who tries them, loves them!

Ingredients for these brownies:

This recipe for cake mix strawberry brownies has a super short ingredient list. Just 4 simple ingredients + 3 ingredients for the glaze is all you need!

  • Flaxseed meal + water. Typically, this recipe would be made with eggs, but to veganize it, we’re mixing ground flaxseed with water to make flax eggs
  • Strawberry cake mix. You’ll need a box of strawberry cake mix. Double check that it’s vegan, if desired. I used Duncan Hines Perfectly Moist Strawberry Supreme Cake Mix.
  • Vegetable oil. A little added oil will yield brownies with the perfect moist texture.
  • Glaze. Don’t leave the glaze off. It really makes these brownies special! It’s a simple mix of powdered sugar, plant-based milk and vanilla extract.

How to make strawberry brownies with a cake mix:

Turning a boxed cake mix into brownies is incredibly easy! Here’s how:

  • Prepare oven and baking pan. Preheat your oven to 350ºF. Spray an 8×8-inch baking pan or dish with nonstick baking spray or line it with parchment paper.
  • Make flax eggs. Stir to combine flaxseed meal and water in a small bowl. Place the mixture in the fridge to set for 10 minutes. 
  • Combine all ingredients. In one large bowl, stir all of the ingredients together, including the flax eggs.
  • Bake. Transfer the batter to the prepared baking pan and evenly smooth out the top. Bake for 33-35 minutes, or until a toothpick inserted into the brownies comes out clean. 
  • Make the glaze. Remove the brownies from the oven and place the pan on a wire rack. While the brownies are still warm, whisk together the glaze ingredients and pour the mixture evenly over the warm brownies.
  • Cool and serve. Let the brownies cool in the pan for about 1 hour, then cut into squares and enjoy!

Tips for perfect brownies:

This strawberry blondie recipe could not be easier, but here are a few tips to make sure your dessert turns out perfect every time.

  • Flax eggs. If you don’t have flaxseed meal, place whole flax seeds in a coffee or spice grinder and pulse them 10-15 times, or until coarsely ground. If you aren’t concerned with keeping this recipe vegan, you could also replace the flax eggs with 2 regular eggs.
  • Cake mix. I love Duncan Hines Perfectly Moist Strawberry Supreme Cake Mix for this recipe. It worked like a charm and was delicious! 
  • Milk. To make the glaze, I used almond milk, but oat or soy would also work – or you could even use water! 
  • Glaze. For best results, you really want the glaze to soak into the warm brownies. Make sure to add the glaze right when they come out of the oven. 
  • Pro tip. To make clean cuts when serving the brownies, warm your knife under hot water and then wipe it with a towel between each cut. These are fudgey brownies so they will stick to your knife a bit!

Brownie variations:

We absolutely LOVED this strawberry version of brownies, but you can really use any favorite flavor of cake mix to create different types of brownies. Here’s some yummy ideas:

  • Funfetti brownies. How festive and fun would brownies with sprinkles be? You could even top the glaze with more sprinkles!
  • Red velvet brownies. Use a red velvet cake mix to make red velvet flavored brownies.
  • Blondies. Try a yellow cake mix for a simple way to make blondies!
  • Lemon bars. Simply replace the strawberry cake mix with a lemon cake mix, maybe add a little lemon zest to the glaze, and you have yourself some easy, delicious lemon bars!

How to store these:

These brownies are best stored in an airtight container for about 3 days in the fridge, but I would be very surprised if they last that long.
