Soft Cocoa Layer Cake with Condensed Milk & Sour Cream Frosting
I always make this condensed milk cocoa layer cake whenever I want a homemade dessert I know will turn out perfectly. Even if the layers aren’t perfectly cut, you can cover them with crumbs and decorate with fresh berries – it always looks beautiful. The cake is moderately sweet, tender, and absolutely delicious when soaked with the cream. If you let it rest in the fridge overnight, it’s even better – the flavors really come together.
This has been one of my favorite go-to cakes since I was a student – many of my friends loved it back then, and it still never fails to impress. Give it a try, and it might just become one of your favorite cakes to share with family and friends. Perfect for a cozy tea time!

How to Make the Condensed Milk Layer Cake
- Melt the butter and set aside to cool slightly.
- In a large bowl, combine the butter, sweetened condensed milk, and eggs. Mix well by hand.
- Add flour gradually and stir, then beat briefly with a mixer or whisk until smooth.
- Activate baking powder with a little lemon juice and mix it into the batter.
- Pour half the batter onto a baking tray (approx. 35×25 cm / 14×10 in), lined with parchment. Smooth it out evenly.
- Bake at 180°C (350°F) for 15 minutes, or until golden and a toothpick comes out clean.
- Remove the sponge and let cool. Cut into rounds using a bowl or into neat rectangles.
- Mix 1 tbsp cocoa into the remaining batter and bake the second layer the same way.
- Save the trimmings and crumble them into fine crumbs — you’ll use this for decoration.
Make the Cream:
- In a bowl, combine sour cream, condensed milk, powdered sugar, softened butter, and lemon juice.
- Mix until smooth with a spoon or whisk. Taste and adjust sweetness as desired.
- Chill the cream while the layers cool.
Assemble the Cake:
- Alternate the white and cocoa sponge layers, spreading cream between each one.
- Frost the top and sides with remaining cream.
- Sprinkle with cake crumbs and decorate with berries and mint leaves.
- Cover and chill for 4–5 hours or overnight for best texture.
Tips for the Best Result
- Let the butter cool slightly before mixing – it helps create a tender, smooth cake texture.
- Add lemon to the cream – it balances the sweetness and adds a fresh, bright flavor.
- Chill longer for best results – the cake becomes even more tender and flavorful after resting.
- Cut with care – use a bowl or cake ring for perfect rounds, or slice into rustic rectangles for a casual, homemade look.
- Store in the fridge – the cake keeps beautifully for up to 3 days.
FAQ
Can I make the cream ahead of time?
Yes! The cream can be prepared a few hours in advance and stored in the fridge until you’re ready to assemble the cake.
Do I have to use cocoa?
Not at all — you can leave the entire cake plain, or divide the batter into three colors for a fun layered effect.
What if I don’t have berries?
No worries! Decorate with cake crumbs, shaved chocolate, chopped nuts, or simply dust with cocoa powder.
Can I freeze this cake?
The cake is best enjoyed fresh or after chilling overnight, but slices can be frozen if tightly wrapped and thawed in the fridge before serving.
