A Childhood Favorite!

Todays Frosted Brownies dessert is one my mom has been making for decades. We’ve known and loved these addicting brownies all of our lives and we love that our own kids know and love them as “Grandma’s Famous Brownies”.

Although most brownie recipes do not have a frosting, the frosting on these bars is so simple and so delicious, it takes regular brownies to a whole new level.

Why we love it:

  • Extra special. The frosting adds a decadent and creamy texture that provides a perfect balance of sweetness.
  • A feast for the eyes. The glossy finish that makes the brownies look irresistible.
  • Still quick and easy. You’re taking Homemade Brownies to the next level but they are still ready in only about 30 minutes!

    I made these in a glass 8×8 pan, baked for about 50 minutes and they are still not fully cooked in the middle. They taste good and I will try them again. But I’m going to put them in a 9×13 and double the amount of frosting.

      Sorry to hear they didn’t bake through for you. I appreciate the feedback and giving the recipe a try!

    I just made the frosting to ice box mix brownies and it worked!!! I re-read the recipe many times because I was skeptical that you only need 1 1/2 tablespoons of both butter and milk and 1/3 cup of sugar, especially if you have to boil them but I followed the instructions, boiled for 30 seconds and took off heat, added chocolate chips and poured right away and it was 😃 great! It set so quickly at the edge of the pot so if I didn’t ice immediately there would have been a situation! Thanks for sharing your recipe 💕
