Easy Sour Cream Cake with Creamy Chocolate Frosting

Easy Sour Cream Cake with Creamy Chocolate Frosting is my family’s favorite dessert recipe. This cake is chocolatey, moist, and dangerously delicious!

Yes, yes, this cake starts with a short cut. I used a cake mix here…sue me.

My grandma used to make this cake, your grandma probably made this cake… it’s a whole thing in the world. I generally do love a completely from “scratch” recipe, but sometimes the magic cake mix fairies sprinkle their love dust on my brain and convince me to pull a little semi-homemade action.

When fairies come-a-calling…you know how it goes…

If the weekend had an official cake, you’re looking at it. Plus, let me just say that creamy chocolate frosting on top is super legit.

The easiest and creamirst chocolate frosting ever! I use it to top my Simple Sour Cream Cake!

You basically doctor up a cake mix with a little sour cream, an extra egg, an eensy bit more sugar…

It gives it a slightly denser texture, but totally soft.

Sour Cream Cake batter

It bakes up like perfection. I almost always make this in a 9×13 pan, because when I’m short-cutting and using a cake mix I’m generally looking for simple decorating too.

But for all you over achievers out there this cake is 100% perfect for baking in 8- inch round pans and layering!

The easiest and softest sour cream cake!

The secret to this chocolate frosting is evaporated milk. It makes the frosting SO creamy.

The creamiest chocolate frosting ever!

Just spread it all over your cooled cake…

Gorgeous and stunning and beautiful and pretty and sexy and on fleek and cute and attractive and foxy and hot and…and…and…

This is the easiest and softest sour cream cake ever. My family asks for it again and again and the chocolate frosting is easily the creamiest I ever had!

…simple, delicious and no fuss.

Shouldn’t all cake be like this?

  1. This cake is amazing, plain and simple. I followed the recipe as close to exactly as possible. We had lower fat sour cream so I used that and we beat the cake by hand but other than that we did it as written. This cake is just plain delicious… flavorful with that hint of “hmm what’s that” (sour cream), moist, fluffy but still good structure. There’s also the hint of nostalgia. It tastes very similar to the simple but delicious cakes my grandma used to make. I never take the time to leave reviews. If you’re on the fence, make this cake!
    Note: We used the Betty Crocker Supermoist Butter Recipe Yellow cake mix for where the recipe calls for yellow cake mix.

    Thank you for this recipe!
