How to Make Strawberry Sour Cream Cake
(For full recipe card scroll to the bottom of this post!)
This strawberry sour cream cake is made with the traditional creaming method of mixing (as opposed to the reverse creaming method), giving it a nice fluffy texture.
Advantage of Sour Cream: The boost of acidity from the sour cream in the recipe softens the gluten, making for a more tender cake. Sour cream also adds a richness to the cake batter. We love cakes with sour cream!
Combine Flour, Salt, and Leavening: In a medium sized bowl, add flour, baking powder, baking soda and salt. Whisk to blend for 30 seconds. Set aside.
Combining Wet Ingredients: In another bowl combine the sour cream, strawberry puree, vanilla, strawberry extract, & oil- blend and set aside.In the bowl of your mixer blend the butter until smooth, Gradually add the sugar and mix on medium speed 3 to 5 minutes until fluffy and lightened in color.
Add the room temperature eggs one at a time mixing until the yellow of the yolk disappears.
Alternating Dry and Wet: Add the flour mixture and the sour cream mixture alternately, beginning and ending with the flour mixture (3 additions of dry ingredients, 2 additions of wet ingredients. Mix until combined and smooth, do not mix above medium speed or over mix.
Time to Bake! Divide the strawberry cake batter between the three 8 inch cake pans. Bake at 350 degrees for 22 to 25 minutes or until a toothpick inserted into the center of the cake comes out clean or with just a few crumbs attached. Let cool 5 to 10 minutes, then turn out.
Should I freeze My Cake Layers?
Freezing cake layers is an optional step but one that I try to make time for. After removing your cake layers from the oven, allow the cakes to cool (still in their pans) on a cooling rack for about five minutes before flipping them out.
Wrapping the Cake Layers
While still warm, I place each cake layer on a foil-wrapped cake board (so that the boards can be reused). Then, I wrap the cake layer in plastic wrap & foil, and into the freezer they go.
The layers actually become more moist in the freezer thanks to the trapped moisture from the warm cake being placed in the freezer.
I freeze my cake layers even if only for a few hours (but they can be frozen for up to three months and will still taste as fresh as the day they were baked)!
Thawing the Cake Layers
When it's time to assemble the cake, just thaw on the countertop, still wrapped. After condensation forms on the foil and the thawing is well underway, you can go ahead and remove the layers from the foil and continue thawing.
Many decorators prefer to assemble the cake while the layers are still partially frozen as they are easier to handle but that is up to you!
Fillings and Frostings for Strawberry Cakes
There are so many amazing pairing options for strawberry cakes. Today, we are using white chocolate frosting and a flavorful cooked strawberry filling for a fantastic White Chocolate Strawberry Cake, but the options are endless. Here are a few other favorites!
- Strawberry Buttercream
- Whipped Strawberry Cream Cheese Frosting
- Cream Cheese Frosting
- Sweetened Whipped Cream Filling (coupled with sliced strawberries)
Assembling our Strawberry Sour Cream Cake with White Chocolate Frosting!
Place the first cake layer on your pedestal or cake base. Spread with a layer of white chocolate frosting, and then spread on the cooked strawberry filling (YUM!). This strawberry filling adds so much strawberry flavor to every bite.
- You can pipe a dam of your frosting before adding the strawberry filling if you'd like to make sure that the filling stays fully enclosed.
- My filling was pretty thick though and so I wasn't worried-- just keep it about ½ inch from the edge all the way around to be on the safe side.
- Add the next strawberry cake layer and repeat.
- Finally, add the third layer, fill in any gaps between layers with your frosting (I do this with a piping bag with the tip snipped away), and then frost the cake.
- I like to frost my tier on a turntable when possible, so that I can easily spin it as I smooth the frosted sides with a bench scraper.
- Then, I like to chill the tier in the freezer for about 10-15 minutes until firm and then go over it once more with a hot bench scraper and spatula. This step is great for smoothing.
- As a final touch, I added a few rows of shell border around the top of the cake using a piping tip 21, and then I filled inside of it with lots of chocolate curls! (Technically these are white chocolate candy coating curls, but you could use white chocolate also).
How to Make Chocolate Curls
I love mounding chocolate curls onto cakes for a little bit of fancy ;0)
I have a mini loaf pan that I like to use for creating curls (it is about 3x6 inches). First, I melted a few blocks of chocolate candy coating/bark coating (I used CandiQuik) in the microwave in small increments.
When the candy coating is almost completely melted, just let it sit for a couple of minutes and then stir to help any remaining pieces disappear.
Then, I poured my melted candy coating into a *foil lined* mini loaf pan and placed in the freezer for about 15 minutes or until firm. You can refrigerate also or even let it firm up at room temperature but it will take longer.
Do you have to use Strawberry Extract in this recipe?
We use strawberry extract to add a little boost of strawberry flavor in most of our strawberry cake recipes. Although this recipe does contain ½ cup of strawberry puree, the strawberry flavor of the cake layers alone is fairly mild.
However, if you do not wish to use strawberry extract, the strawberry filling in this recipe is wonderful and lends a really nice strawberry flavor.

- ½ teaspoon (3g) baking soda
- ½ teaspoon (3g) salt
- 1 cup (227g) sour cream
- ½ cup (129g) strawberry puree (Puree fresh or frozen strawberries)
- ¼ cup (54g) vegetable oil ( I use canola oil)
- 2 teaspoons (8g) strawberry extract
- *Pink Coloring Gel- Optional. We just used a small amount.
For the Strawberry Filling
- 2 cups chopped strawberry (fresh or frozen — chop in rather small pieces)
- ¼ cup (50g) sugar
- 2 Tablespoons (18g) cornstarch (cornflour in the UK)
- 1 Tablespoon (9g) water
White Chocolate Frosting
- 3 sticks (339g) unsalted butter, softened (do not soften in the microwave)
- 8 ounces (227g) white baking chocolate (I used 2 Ghirardelli Premium Baking Bars)
- 5 cups (575g) powdered sugar
- 1 teaspoon (4g) vanilla extract
- 4 tablespoons (42 g) milk or cream
- ½ teaspoon (3g) salt (optional to cut the sweetness)
- Whole fresh strawberry or strawberries for top
- White chocolate candy coating for curls (You could also use a white chocolate bar)
- *I also piped three rows of shell border around the top with a piping tip 21.
For the Strawberry Sour Cream Cake
- Preheat the oven to 350 degrees, grease and flour three 8 inch x 2 inch round cake pans. You can use two 9 inch pans, just lengthen the baking time a bit.
- In a medium sized bowl, add flour, baking powder, baking soda and salt. Whisk to blend for 30 seconds. Set aside.
- In another bowl combine the sour cream, strawberry puree, strawberry extract and oil, blend and set aside.
- In the bowl of your mixer blend the butter until smooth. Gradually add the sugar and mix on medium speed 3 to 5 minutes until fluffy and lightened in color.
- Add the eggs 1 at a time mixing after each until the yolk is blended
- With the mixer on low speed, add the flour mixture and the sour cream mixture alternately, beginning and ending with the flour mixture (3 additions of dry ingredients, 2 additions of wet ingredients.) If adding a little pink coloring gel, you can do so at this time.
- Mix just until combined.
- Bake at 350 degrees for 22 to 25 minutes or until a toothpick inserted into the center of the cake comes out clean or with just a few crumbs attached. Let cool 5 to 10 minutes, then turn out.
For the Strawberry Filling
- Add all ingredients to a small saucepan. On medium/high heat allow mixture to come to a boil.
- Stir as the sugar begins to melt and the strawberries soften. When the mixture begins to boil, lower the heat and stir constantly until the mixture begins to thicken.
- You can press some of the strawberries against the side of the pan as they soften. Pour into a heat proof bowl to cool. It can be refrigerated in an air-tight bowl until ready to use. Use within 5 days. This makes enough filling for a 3 layer cake.
For the White Chocolate Buttercream
- Cut/chop the white chocolate into very small pieces, put into a microwave safe bowl and add 4 Tablespoons milk or cream.
- Microwave for 15 seconds let sit for a minute or two, stir and microwave again 15 seconds letting it sit a minute to soften further, stir. Be careful not to over heat the chocolate. The chocolate will continue to melt as it is stirred. Let the chocolate cool down before using.
- Beat the butter until softened and smooth, add the powdered sugar 1 cup at a time. Add the white chocolate and milk mixture. Add vanilla and salt. Add another Tablespoon milk if needed. Beat on medium speed for 3 to 4 minutes and it will become smooth and creamy.
- Makes 5 cups frosting. Makes enough to frost a 2 or 3 layer eight inch cake. If you will be doing a lot of decorative piping, you will need additional frosting.
Assembling the Cake
- Place the first cake layer on your pedestal of cake base.
- Spread with white chocolate buttercream within about ¼ inch to ½ inch from the edge of the cake. Then spread with about half of the strawberry puree filling on top of that (if you are frosting a three layer cake).
- Add next cake layer and repeat.
- Fill in any gaps between the layers frosting, then frost the cake with white chocolate frosting. Garnish with white chocolate curls & strawberries.
Substitution for cake flour: Using all purpose flour (plain in the UK) for each cup of flour in a recipe, remove 2 Tablespoons of flour replace with 2 Tablespoons cornstarch (cornflour in the UK). This recipe has 3 cups of flour so you will measure out 3 cups of all purpose flour, remove 6 Tablespoons and replace with 6 Tablespoons cornstarch, whisk to blend.
This recipe makes 7 cups batter. Works well for cupcakes, for standard size cupcakes bake at 350 degrees for 18 to 20 minutes.
