Why these Brownies are the Best!

If you’re into moist and chocolaty treats, these brownies are for you. Made with melted semi sweet chocolate and sour cream, these brownies give you all of the flavor you love without a lot of work.

Here, the color and flavor of the brownie comes from the combination of melted butter and chocolate, rather than cocoa powder. This helps to keep the brownies nice and light.

The sour cream helps to keep these brownies extra moist. It is also a great way to use up leftover sour cream. Opt for the full fat sour cream if you have it.

You only need a few ingredients to make sour cream brownies: semi sweet chocolate chips, butter, eggs, sugar, vanilla, flour, and sour cream. For the frosting you will need: butter, cocoa powder, vanilla, milk, and powdered sugar.

  • Sour Cream: use full fat sour cream if you have it. Low fat works but it won’t give you same texture.
  • Butter: use room temperature butter for melting with the chocolate chips. Unsalted or salted works.
  • Cocoa Powder: this recipe calls for cocoa powder in the frosting instead of the batter. I like the keep the brownie batter light but give the frosting that dark bite.
  • Chocolate Chips: to avoid making the brownies too sweet, opt for semi sweet chocolate chips instead. Dark chocolate chips would work too.

  1. I made it without the frosting and crushed Oreos as the chocolate chips and it tasted so good
    It was fudgy, not too sweet and Delicious
    I would make again

  2. 4 stars
    Although these were tasty, mine sunk a bit and not sure why. And I followed the tips for the frosting, but it was just too hard and unspreadable for me. So I ended up making a different frosting.

    1. I was concerned about the recipe, not having baking powder or soda, and didn’t know if they would rise but they did very nicely the top of the brownies were It rather crusty but it’s OK. The frosting recipe was a little thick, but I just added warm milk and it thinned it out. I put it on the brownies when they were still warm so it’s soaked into the brownies some and it really made them moist and delicious.

  3. 5 stars
    Delicious! I had some creme fraiche (which is essentially sour cream with higher fat content) and used that instead and these brownies turned out amazing! They flew off the table before I even had time to make tea! Will double the recipe next time 🙂

  4. 5 stars
    I have never made brownies with sour cream but I have done cakes and other treats and it totally makes sense that it would make them extra fudgy and rich. Great recipe!
