Cake Mix Brownies

This easy chewy and fudgy cake mix brownies recipe requires simple ingredients. It tastes homemade and is a quick dessert or quick snack for parties.

Sweet and salty desserts are one of my many WEAKNESSES and these pretzel cake mix brownies hit the right mark when the cravings hit me in full force yesterday.

Imagine eating a slice of insanely FUDGY brownies, topped off with RICH chocolate ganache and salted pretzel bits.

When I am short on time or if I don’t have all the ingredients for my fudgy brownies with crackly tops recipe, I make these brownies from Devil’s food cake mix.

This is a QUICK dessert and people can ever tell they are not homemade.

Easy Cake Mix Brownies Recipe

Here are some TIPS for making simple cake mix brownies:

  • I used Devil’s Food cake mix because it gives the best intense chocolate flavor but you can also use chocolate cake mix to make brownies.
  • You can use any brand of cake mix you like.
  • DON’T replace butter with oil because butter is needed for that fudgy brownie texture.
  • Use whole milk since it has higher fat content.
  • This recipe can easily be DOUBLED if you want to make a bigger batch. The pictures in this post show a bigger batch coz I wanted a “taller, thicker” brownie.
  • Pretzels are entirely OPTIONAL but if you add them, make sure to add them just prior to serving or else they will become soggy. You have to press them a but into the ganache.
  • DON’T over-bake brownies or else they will become dry! I prefer my brownies under-baked because they are so fudgy this way.
  • You can replace ganache with your favorite chocolate buttercream frosting too.

Here are some FLAVOR variations you can try for these quick brownies:

  • Use different flavored box cake mixes to make red velvet cake mix brownies, lemon cake mix brownies, yellow cake mix brownies.
  • Stir in your favorite chopped candy bars and make cake mix candy bar brownies.
  • Stir in chopped Oreos into the batter to make cake mix Oreo brownies.
  • Stir in some chopped salted nuts to make walnut brownies or pecan brownies.
  • Drizzle salted caramel sauce on top of the brownies to make caramel brownies.
