Gooey Chewy Brownies (with a secret ingredient)!

This post may contain affiliate links. Please read my disclosure policy.

These brownies are moist, gooey and chewy with the addition of a secret ingredient!  There are two methods for this recipe…  one uses a box mix as a starter (I like easy) and one is from scratch!

The Secret Ingredient

These will stay nice and fudgy with the addition of a surprise ingredient…  sweetened condensed milk!  Once you add it to your brownie mix the first time, you’ll always want to bake them that way!

I topped mine with Oreo cookies…  feel free to add your own yummy twists like:

  • 1/2 cup of nuts (pecans or walnuts)
  • 1/2 cup chocolate chips
  • 1/3 cup coconut

Be sure to keep an eye on them when baking.  You want them cooked but not overcooked!
