Chocolate Raspberry Cake #SundaySupper

An indulgent and moist chocolate cake, with raspberry filling layers, and a creamy, decadent, and easy chocolate frosting
Amazing Raspberry Chocolate Cake and Frosting Recipe

Guess what!? It’s Jack’s birthday week. He turns two on Wednesday, and in honor of my perfect, sweet little boy, I will be posting birthday themed posts throughout the week!

I still stand by my statement that this is the world’s best chocolate cake recipe. Because, well, it is. And it’s perfect for birthdays (though, not Jack’s. Too much milk in it for him!)

And this recipe is also the world’s best chocolate cake recipe…because it’s the same one. However, I changed up the frosting, and added some delicious raspberry to it, so, I thought I’d share these fun and very indulgent modifications with all of you. And this has also been modified to be used as a layer cake, rather than in a 9×13 pan.

Amazing Chocolate Cake Recipe

Oh, and I figured out the secret to making this cake perfect. Even though it always tasted delicious when I made it in Colorado, it always sunk a little in the middle. However, it turned out perfectly here in Utah, which is where my great-grandmother perfected it. So, basically, you have to live in Utah for this recipe to be perfect. Sorry for all of you non-Utah living people 😉

Amazing Chocolate Raspberry Cake and Frosting Recipe

I’m actually not a huge fan of cream cheese frosting (I know, crazy me), which is what I typically have been making the chocolate cake with. However, when Forrest’s sister requested a chocolate cake for her birthday, I decided to come up with a chocolate frosting recipe…and you guys, I am going to be using this frosting from now on. It is SO good.

Best and Easiest Chocolate Frosting Recipe


I seriously just wanted to eat it by the spoonfuls (I didn’t though, rest assured.) Combined with the yummy raspberry filling that I put with the cake, and the obviously delicious cake, it was almost too much to handle. Almost being the key word.

This cake is very light and moist when you take it out of the pan, so handle with care. I was going to cut each layer in half, so I could add more raspberry filling, but I was really worried it was going to break the cake…so be aware of that if you are more daring than me!

Chocolate Raspberry Cake
  • Chocolate Cake
  • 1 cup vegetable oil
  • 1 cup buttermilk
  • 2 egg
  • 1 teaspoon vanilla
  • 2 cups cake flour
  • 2 cups sugar
  • ¾ cup cocoa powder
  • 1 teaspoon salt
  • 1 Tablespoon baking soda
  • 1 cup boiling water
  • Frosting
  • 1 cup softened butter
  • ½ cup cocoa powder

  1. Chocolate Cake
  2. In a mixing bowl, beat together oil, buttermilk, egg, and vanilla.
  3. In a separate bowl, mix together flour, sugar, cocoa powder, salt, and baking soda until well-combined.
  4. Slowly mix the dry ingredients into wet ingredients, and mix until everything is smooth, and no chunks exist.
  5. After the wet and dry ingredients are combined, add in the cup of boiling water. Mix well. Batter will be slightly runny.
  6. Pour into two well-greased and floured cake pans.
  7. Bake at 350 for 25-30 minutes, or until a toothpick comes out clean. Cake will be very moist, but the toothpick should be clean.
  8. Frost once cool.
  9. Frosting
  10. In a large bowl (preferably a stand mixer) whip butter and cocoa together until smooth.
  11. Whip in vanilla.
  12. Slowly add powdered sugar in, about ½ cup at a time. You may use less or more, depending on the consistency you want.
  13. Slowly stir in about 3 tablespoons of milk.
  14. Whip until smooth (about two minutes)
  15. Assembly
  16. Invert one cake onto plate.
  17. Spread a layer of raspberry.
  18. Slowly place the other cake on top of raspberry (be very, very careful. The cake is very delicate). Alternatively, you can divide the layers if you want more than one layer of raspberry.
  19. Frost the cake.
  20. Serve!

      Believe me, it was so hard not to eat it by the spoonful!! Thanks so much 😀 We left it with my sister-in-law, since we originally made it for her birthday, and oh man, I was so sad to leave it behind. My waist line thanked me though 😉

  2. says

    Seriously – what is it about homemade frosting that is SO SO GOOD? Yours looks incredible…and it makes me want to whip up a batch immediately. And eat it with a spoon. I could do that, right?

    Oh yes, that is one amazing chocolate cake. The touch of raspberry makes it divine. Thanks for joining in Sunday Supper and hope to see you do so more in the coming year.
