Crack Brownies

Crack Brownies Recipe

Recently, I searched, “How to make boxed brownies better” and came across a simple hack.  That hack has since become one of my favorite dessert recipes, especially for the holidays.  I’ve inherited the title of “Family Fudge Maker” from my mawmaw and it’s definitely a Christmas must-have for most of my family members on my mom’s side.  Mawmaw’s fudge is so decadent.  Dare I say that I like these brownies even better?  They are positively sinful.

A lot of desserts call for a ton of ingredients, multiple steps and a lot of time invested. That’s another reason why I love this recipe so much, it’s so simple that it’s almost impossible to mess them up.

Recipe Notes

You can use any combination of brownies and chips that you want. I’ve made several batches now and my favorite combination has been dark chocolate brownies with milk chocolate chips. They melted into the most incredible ooey gooey dessert I’ve ever tasted. Topped with ice cream, they are the closest thing your tastebuds will get to heaven.

If you don’t like gooey brownies, then go with a traditional brownie mix (like pictured above) and follow the instructions for cake-like brownies. Personally, I don’t think this version comes anywhere near close to the gooey version, but my hubby prefers this style. To each your own!

If you have a Christmas party coming up, consider giving this delicious dessert a try!

    Another great brownie hack for yummy and gooey boxed brownies is adding (…sounds gross but wait for it) a big cup of mayonnaise! If you think about it, Mayo is made with oil and eggs so it makes them very moist. When my boys were growing up all their friends always begged me to make what they called, “God Brownies” (because they’re so good lol) To this day whenever their friends visit, I’m still asked to make them.

        What do you do with the other half can of condensed milk?

          Eat it with a spoon!!!! Or pour it over snow cones. Or maybe make a second batch of brownies!

      Mini years ago we were all eating a chocolate cake at a party and everybody was raving about it until they said it was made with mayonnaise and everybody just stopped and looked at each other. It was amazing and you would never have known it was mayonnaise.

        I have made mayonnaise cake since1960.

      I’ve always used mayonnaise instead of oil for packaged brownies and cakes. My mum taught me that. Aldis has a brand that works well. Just use the same amount that is called for the oil.

    • Becky
      June 22, 2020 / 5:52 PM

      Do you substitute the mayo for the eggs and oil or in addition to them?

      • Lauren Munro
        July 1, 2020 / 11:40 AM

        Wondering the same – do you changed the ingredients or do you just add the mayo?

      • Megan S Colucci

        Substitute the mayo for the oil in direct proportion. The eggs don’t change — add as it says on the box. Just the mayo for oil is swapped.
        I make all my cakes/brownies with mayo as a substitute. Much more moist than with the oil.
        Now I am a Hellman’s girl, through and through. So I cannot attest to any other brand being good 🙂

        I use the mayo instead of the oil but still use the eggs.😊

    • July 16, 2020 / 12:06 PM

      How much mayonnaise in does it replace the other ingredients or is it in addition to to the other ingredients

    • August 24, 2020 / 11:54 PM

      I’m a miracle whip user. Can I use that or it has to be real mayonnaise

      • August 25, 2020 / 10:30 AM

        I’ve never tried Miracle Whip or Mayo in this recipe.

      Does the cup of mayo replace the eggs & oil. Or is in ” in addition to”?! Thanks for the tip!!

    • Julia
      October 2, 2020 / 12:23 PM

      Do you add that addition to the ingredients listed in this recipe?

      Hey, once you add the chocolate chips on top do you place it back in the oven to melt?

          it seems like the chips would need to melt!

          • Margo
            September 20, 2020 / 8:09 PM

            The recipe doesn’t seem complete. Once you have it the choc chips on do you put it back in the oven or do they not melt?

      • Marie
        July 5, 2020 / 6:09 AM

        Do you have to put the brownies back in over after adding condensed milk and chips and for how long?

    My 9×13″ brownie mix usually makes a thin layer so I always use 2 mixes. Can I double your recipe?

    • Kim
      September 30, 2020 / 6:54 PM

      How long do the brownies need to sit, to completely soak in the condensed milk?

    Does your box of brownies say it makes an 8×8 or 9×13? My box says 8×8… so just curious what your box says!

    • May 2, 2020 / 8:32 PM

      I prefer my brownies thinner so I use a 9×13. 🙂

    You received a comment about doubling the brownie mix, you replied “sure”, do you also have to double the condensed milk and the chocolate chips.

    Also, if you replace the oil with mayonnaise do you use the same amount of mayonnaise as the oil and is that the only thing you replace in the recipe.


    • May 4, 2020 / 8:15 AM

      If you double a recipe, you need to double all of the ingredients. 🙂
      I have never baked brownies with mayo, so you would need to google.

  12. Becky
    June 7, 2020 / 7:20 PM

    Do these brownies need to be kept in the refrigerator?

  13. Jennifer
    June 9, 2020 / 8:28 AM

    So you don’t bake anymore after you pour the condensed milk and chocolate chips on top?

  14. Barbara
    June 11, 2020 / 9:41 AM

    Hi, I’m dying to try these for my daughter’s bday party – my one question – after you pour on condensed milk and chips do you bake again? Or that’s it – you just let cool and serve?

    Thanks so much!

    Walmart substituted the brownie mix that I ordered for a different brand. They call for 1 egg. Should I use 2 as your recipe says?

  17. Debbie
    July 16, 2020 / 8:12 PM

    What do you do with the other half of the can of condensed milk?? Make another pan of brownies? 😉

    I make brownies according to directions and before baking add 1 cup sour cream and 1/2 cup chocolate chips or whatever flavor you want. You can also add nuts if you like.

  23. Christine

    I noticed the bag of chocolate chips in your picture are semi-sweet chocolate but the recipe calls for milk chocolate chips. Did you use milk chocolate? Thanks.

    • Angela Lanter
      October 12, 2020 / 4:45 AM

      I use both. Just whatever I have on hand.

    I only have triple chocolate brownie mix which has chocolate chips and chunks in the mix. Do you thunk this would still work?

    • Angela Lanter

      Oh, I’m sure it would!
