Every cook should have a cake recipe that is so simple to make they don't have to depend on a boxed mix to come to their rescue when having guests coming over unexpectedly or simply lacking in time. This cake should also taste so phenomenal that guests will beg for the recipe and family members will repeatedly request it. Too much to ask, you say? Not with this cake.
In all the years that we've been making it, it is so popular with friends and family that we make it for many occasions because it is so loved. This is also the recipe that I give out the most. The people have spoken, not just the cook, who is thrilled not to stand in the kitchen for hours toiling over multiple layers, intricate details and elaborate techniques.
The cake is moist and light, but sturdy enough for the frosting. I use my standard frosting recipe that I use for most of my cakes - light, fluffy and creamy. The addition of fresh raspberries gives the cake such a refreshing taste and since I absolutely adore raspberries, I think it gives it the perfect sweet and tart note of spring. The cake is very versatile, so you can adjust it to your taste and add any berries, fruit, nuts, chocolate or candy. Since it's so easy to make and is made up of pieces of cake, this is literally a "Piece of Cake".
Ingredients:
Cake:
6 eggs
1 cup sugar
1 ½ cups sour cream
1 ½ teaspoons baking soda dissolved in 1 teaspoon of vinegar
1 ½ cups flour
Frosting:
1 (8 oz) package cream cheese
1 can of condensed milk
1 (16 oz) package sour cream
2 teaspoons vanilla
1 cup heavy cream, very cold
1 pint fresh raspberries
Instructions:
Preheat the oven to 350 degrees Fahrenheit. Line a 13x9 inch deep baking pan with aluminum foil.
With a whisk attachment on a standing mixer or using a hand mixer and a large bowl, mix the eggs and sugar until light and fluffy, about 5 minutes. 
Add the sour cream. Dissolve the baking soda in vinegar and also add to the cake batter. Mix to combine. 
Add the flour and mix until incorporated. The batter will still be on the thinner side. 
Pour into prepared baking dish. 
Bake for about 30 - 35 minutes until cake springs back to the touch and a toothpick comes out clean. 
Cool slightly, just until you can handle it. Tear the cake into pieces. This is the fun part. I always feel like I'm one of the elders in a Russian church breaking bread for communion. The cake should be almost cool when you're done tearing it apart, but if it isn't, just set aside until it's completely cool. 
The texture of the cake is not like a typical sponge cake. It's much more dense. If the cake was light and fluffy and light as a sponge cake, the cake would completely disintegrate when tossed with the frosting. 
Meanwhile, make the frosting.
With a paddle attachment on a standing mixer or using a hand mixer, mix the cream cheese until creamy and it has an even consistency. Add the condensed milk. Mix to combine. Add the sour cream and vanilla and also mix to combine. 
In another chilled bowl with a chilled whisk attachment, whip the very cold heavy cream until stiff but still somewhat soft peaks form. 
Gently fold the whipped cream into the rest of the frosting with a rubber spatula. 
When the cake is cool, pour in part of the frosting and mix.
Keep adding more frosting until all the the cake is completely covered in frosting, but don't add too much or the cake will be mushy. Set aside the remaining frosting to spread over the assembled cake. Add the raspberries to the cake and VERY GENTLY mix to combine. 
You can form the cake into any shape that you like - circle, square, etc. You can also use the sides of a springform pan to help you shape it, by placing the rim on top of the serving plate, putting the cake inside the springform and then taking the springform off. 
You can even form it into a heart for a romantic date or Valentine's Day. You can even do a free form shape by plopping all the cake onto a serving platter and making a rounded shape, covering with the remaining frosting and decorating however you please. 
Cover with the remaining frosting and decorate with chocolate shaving, chocolate glaze, berries, nuts or whatever else you like. I like to use THIS RECIPE of chocolate glaze to drizzle over the cake and then add some raspberries. 
Store the cake in the refrigerator. You can serve it right away, but it is best served after having a few hours to chill in the refrigerator.

Hi Olga! Love your blog, will be making this cake today. Tried to save the recipe, but it took me to a site that is no longer available. Is it just me? Thanks for checking!
Hi, Olya. Me and my 4-year old girl made this cake yesterday. We both enjoyed making it. It looks great! My husband doesn't like sweets but he just had 2 pieces before going to work and also asked for a piece to go 🙂 I did not have raspberries and used blueberries from our garden instead.
P.S. I just met a wonderful girl who told me about your blog. And I just loved it from the first post I read. Thank you.
Welcome, Galina. I'm so glad you stopped by. That's phenomenal, that your husband who doesn't usually enjoy sweets liked the cake too. I'm sure the blueberries were delicious too!
Olga, my niece made this cake for my son's birthday. it was devoured. not a single crumb left! i would like to attempt to make this cake myself. Is there a printer friendly button that I'm not seeing? i would like to print it out. thanks
I'm so glad you all enjoyed the cake! I'll put in a printable recipe version.
Hi Olga , if I use strawberries for this cake how do u recommend I cut them up ? I've made this cake with raspberries before and it was delicious and now I have some strawberries so ill be using that. Thank you for your great recipes !
It really doesn't matter, Ana. However you like.
yum. this looks so delicious. i need to try this recipe
Thanks, Lidiya! Enjoy:).
Quick question, I ran out of foil, can I use parchment paper instead?
Yes, Olga. Parchment paper will work too.
Is it ok to use cool whip instead of heavy whipping cream?
Yes, you can use Cool Whip, Lily.
this cake is absolutely amazing!!!! Our family's new favorite!!!! Thank you for this sharing this delicious recipe!!!
I'm so happy to hear that, Olga! We make it for most family celebrations too.
I made this on Sunday....so tasty! It's easy to make, the frosting is so yummy, my 4 and 3 year old kids licked the bowl clean 😉 I decorated the cake with raspberries and very small chunks of peanuts and cashews all over. The nuts added a bit of crunch, it was deeeelish! Thank you Olga!
Nuts are a great addition; I especially like peanuts in cakes:). How fun to have little ones licking the frosting bowl!
I was wondering if i can substitute fresh raspberries for frozen.
"I tried using frozen raspberries before, and it works ok, but not great, since the berries unthaw and make the cake around them a little wet." (from an above comment)
olga, can I make this the night before? Im in a hurry for this and was wondering if I can add raspberries and cream just make the cake altogether and serve tomorrow during lunch?
Yes, Alana. You can definitely make it ahead of time. If you bake it, tear it into pieces and toss it with the raspberries and frosting right before you serve it, it will be just fine. If you omit the raspberries, you can make the cake a day in advance and garnish with fresh berries at that point.
Olga,
Does the condensed milk have to be boiled? or I can use it out of the can for this recipe?
The condensed milk is NOT cooked for this recipe, Dorina.
Thank you Olga 🙂
Everyone loved this cake so much! Thanks for another great recipe Olga! This one's a keeper for sure.
This cake graces our table at most parties. I love how simple it is to prepare but it's so delicious!
Just wanted to say that this was one delicious cake. My hubby loved it and my guests enjoyed it too. Mmm Mmm good! Thanks again for tasty recepies. Oh and BTW its very moist and the cake doesn't need to stand in the fridge very long for it to be perfect. Add more raspberries - for more yumminess. 😉
Awesome! Glad you like it, Olga. You're right, it doesn't need to stand in the fridge for too long. Sometimes, when we're in a rush, we serve it right away.
thank you Olya for this wonderful website and this tasty recipe! Made this cake last week and my husband loved it. It was perfect! Keep them coming! 🙂
