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!

  1. I made these this evening, they turned out really good! the only problem I had was when I poured the condensed milk over the top of the batter as written I got too close to the edges and so the edges of the brownies were hard and chewy, The middle was fantastic! Next time I think I will just add condensed milk to the batter when mixing and not pour the rest over the top. Thank for sharing this recipe4 stars

  2. Everything’s better with sweetened condensed milk! And thanks for making me crave brownies at 10:30pm. ;) ! Thanks for sharing at Inspire Us Thursday on Organized 31.

  3. OH YUM!!! I can never turn down a brownie! I love a soft brownie, so this recipe is perfect! I’ll be sharing this recipe on FB, Twitter and Pinterest. Thanks for linking up to Wake up Wednesdays!

  4. Why not make from a family-size brownie mix and use a 13×9 pan? I’m an odd person that likes to bake but has not brownie pans, lol.

    1. I like the small ones because guess who eats it all… ;) It would work with a 9×13 and family size as well! I would still use just one can of sweetened condensed milk (based on the gooey-ness of the ones I have tried!).

      If you try it, please let us know how it works out for you! :0

  5. Is there any reason for the parchment paper other than easy removal from the pan? It’s not something I have on hand, but have all other ingredients to make this now!
