YEs, sour cream!

If you’re looking for an easy chocolate cake that’s super moist and fudgy – then this sour cream chocolate cake is for you. It isn’t much harder than using a box mix, and it turns out perfect every time. Plus, can you really go wrong with chocolate cake and chocolate frosting?

For the longest time, I was a little unsure about adding sour cream to a chocolate cake. I was worried that it would make the cake taste funny. But you actually don’t taste the sour cream at all. Instead the sour cream makes it super moist and fudgy with the softest cake crumb.

Now, all sour cream doubt has disappeared, and I’m in love with this recipe!

How to Make Sour Cream Chocolate Cake

This recipe uses simple, everyday ingredients that you probably already have in your pantry, including: butter, cocoa, water, sugar, eggs, vanilla, flour, baking soda, salt and sour cream. Here are the easy instructions:

First we add the butter, cocoa and water to a sauce pan to melt everything together and dissolve the cocoa powder. Then remove it from the heat and cool slightly.

Mix in the sugar, eggs and vanilla extract – followed by the flour, baking soda and salt. Last but not least, mix in the sour cream. Bake for 35 minutes.

Let cake cool and make frosting and top with sprinkles.

Frosting + Storing

Feel free to frost the cake with whatever frosting you prefer. I’ve included one of my absolute favorite chocolate frosting recipes. It’s a simple recipe and there’s enough for a thin layer of creamy, chocolate frosting goodness. You could also top each slice with a scoop of ice cream and a drizzle of chocolate sauce if you prefer, or even just a light sprinkle of powdered sugar instead.

You’ll love this sour cream chocolate cake because of its moist texture and delicious chocolate flavor. It’s not too sweet or too rich, but still filled with chocolate. So if you’re looking for an easy chocolate cake recipe – this one is definitely for you!

Leftover cake can be STORED in an airtight container in the fridge for 5-7 days. To store leftovers in the freezer you’ll want to flash freeze the cake by placing the pieces on a baking sheet in the freezer. Once solid wrap each piece with plastic wrap and again with foil freeze for up to 3 months.

    Had to use up some sour cream, so found your recipe. Oh goodness. So moist with the right balance of chocolate flavour and such a lovely crumb and texture. I didn’t make the frosting and it didn’t need it as a snack cake. The whole family loves it, even the non chocolate lover.

    Made this for my daughters 2nd birthday tonight. I was really hoping for that classic box cake mix with sour cream nostalgia and this hit the spot. It turned out fluffy and nice. Whipped up some chocolate frosting and it was a crowd pleaser. Thank you!

  3. I plan on making this the night before. Do you reccomend that I store it at wrapped at room temperature or in the fridge?
