Homestyle Strawberry Layer Cake
This Homestyle Strawberry Layer Cake brings soft pink layers and fresh berry flavor together in one nostalgic, party-ready dessert.
Strawberry cakes have a way of feeling like a celebration all on their own. The tender pink crumb, the creamy frosting, and that sweet berry aroma make every slice feel like a special occasion, even on an ordinary weeknight.
This version keeps things wonderfully simple by starting with a boxed white cake mix, then boosting it with strawberry gelatin, sour cream, and real berries. You still get a from-scratch taste and texture, with way less fuss and a very reliable result.
Baked in two layers and finished with a fresh strawberry buttercream, this cake is perfect for birthdays, potlucks, baby showers, or any time you want a dessert that looks like it came from a bakery but was made right in your kitchen.
What You Need to Make This Homestyle Strawberry Layer Cake
This cake is built from two easy parts: the strawberry layers and the berry-kissed buttercream. Here’s what each ingredient brings to the table so you can bake with confidence.
- White cake mix (15.25 oz) – Forms the base of the cake, giving you a consistent, fluffy crumb without measuring lots of dry ingredients.
- Strawberry gelatin mix – Deepens the pink color and adds that classic strawberry flavor that tastes like childhood celebrations.
- Large eggs – Provide structure, richness, and help the cake rise tall and slice neatly.
- Whole milk – Adds moisture and richness so the layers taste soft and tender instead of dry.
- Vegetable oil – Keeps the crumb extra moist and soft, even after chilling or storing the cake.
- Sour cream – Adds creaminess and a slight tang that balances the sweetness and gives the cake a more homemade flavor.
- Mashed strawberries – Brings in real berry flavor and natural color; fresh or well-drained frozen berries both work.
- Vanilla extract – Rounds out the flavor so it tastes warm and bakery-style instead of overly artificial.
- Unsalted butter (softened) – Creates a smooth, rich base for the frosting that whips up light and fluffy.
- Powdered sugar – Sweetens and thickens the frosting while giving it that classic silky texture.
- Strawberry puree or finely chopped berries – Infuses the frosting with fresh flavor and a pretty pink hue without food coloring.
- Pinch of salt – Balances the sweetness so the frosting tastes flavorful instead of overly sugary.
- Fresh strawberries for garnish (optional) – Sliced or whole berries on top make the cake look extra special and hint at the flavor inside.
Cooking Steps
STEP 1: Prepare the pans and oven.
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment rounds. This helps the layers release cleanly once baked.
STEP 2: Combine the dry base.
In a large mixing bowl, whisk together the white cake mix and strawberry gelatin until the powders are evenly blended. Breaking up lumps here makes the final batter smoother.
STEP 3: Mix in the wet ingredients.
Add the eggs, milk, oil, sour cream, mashed strawberries, and vanilla to the bowl. Beat on medium speed for about 2 minutes, scraping the bowl once or twice, until the batter is thick, smooth, and fully combined.
STEP 4: Fill the pans and bake.
Divide the batter evenly between the prepared pans, smoothing the tops with a spatula so they bake level. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
STEP 5: Cool and level the layers.
Let the cakes cool in their pans for about 10 minutes, then turn them out onto wire racks. Cool completely before frosting. If the tops domed, use a long serrated knife to gently level them so they stack nicely.
STEP 6: Make the strawberry frosting.
In a clean bowl, beat the softened butter until pale and fluffy. Gradually add the powdered sugar, mixing well after each addition. Beat in the strawberry puree, vanilla, and a pinch of salt until smooth and creamy, adjusting with a bit more sugar or a splash of milk for your preferred consistency.
STEP 7: Assemble and chill the cake.
Place one cake layer on a serving plate and spread a generous layer of frosting over the top. Add the second layer, then frost the top and sides of the cake. Decorate with fresh strawberries if you like, then chill for 20–30 minutes for cleaner slices.
Helpful Tips
- Drain the berries well. If using frozen strawberries, thaw and drain them thoroughly before mashing so extra liquid doesn’t make the batter or frosting too loose.
- Avoid overmixing. Once the wet and dry ingredients are combined, stop mixing as soon as the batter looks smooth. Overmixing can make the cake dense instead of fluffy.
- Chill for neat layers. For extra tidy slices, chill the filled cake for at least 30 minutes, then use a sharp, thin knife wiped clean between cuts.
What to Serve with Homestyle Strawberry Layer Cake
This cake shines at spring and summer gatherings alongside light, refreshing drinks. Try pairing slices with homemade lemonade, iced tea, or a simple sparkling water with fresh berries for a pretty, low-effort option.
For a more decadent dessert spread, serve it with a scoop of vanilla or strawberry ice cream and a side of fresh mixed berries. A hot cup of coffee or tea also balances the sweetness beautifully, making it perfect for birthdays, showers, or afternoon coffee dates.
Can I use frozen strawberries instead of fresh?
Yes, frozen strawberries work well. Thaw them completely, then drain off excess liquid before mashing. Too much moisture can make the batter dense and the frosting runny.
How do I keep the cake layers from sticking?
Grease and flour the pans thoroughly, or line the bottoms with parchment rounds. Let the cakes cool about 10 minutes, then loosen the edges with a knife before turning them out.
Can I bake this as a sheet cake?
You can bake the batter in a lightly greased 9×13-inch pan. Bake until a toothpick in the center comes out clean, then cool completely and frost the top as a single layer.
How do I stop the frosting from becoming too runny?
Use softened, not melted, butter and add the strawberry puree gradually. If the frosting gets thin, beat in extra powdered sugar until thick and fluffy, or chill briefly before spreading.
Keeping Leftovers Fresh
Because of the fresh berries and buttercream, this cake keeps best chilled. Cover it tightly with plastic wrap or store slices in an airtight container in the refrigerator for up to 3–4 days. The flavor often deepens by day two.
For longer storage, freeze individual slices or well-wrapped portions of the whole cake. Wrap in plastic, then foil, and freeze for up to 2 months. Thaw overnight in the fridge, then let slices sit at room temperature for 15–20 minutes before serving so the crumb and frosting soften again.
Homestyle Strawberry Layer Cake
Ingredients
For the Cake Layers:
- ½ cup crushed ripe strawberries (fresh or defrosted from frozen)
- 4 whole eggs large
- 1 teaspoon pure vanilla extract
- ½ cup full-fat milk
- ¼ cup thick sour cream
- 1 box 15.25 oz plain white cake base mix
- 1 3 oz packet of strawberry-flavored gelatin powder
- ½ cup neutral cooking oil e.g., vegetable oil
For the Frosting:
- ¼ cup finely minced or blended fresh strawberries
- 1 cup unsalted butter softened to room temperature
- 1 teaspoon vanilla extract
- 3 cups sifted confectioners’ sugar
- A pinch of salt
Instructions
- Preheat your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing and dusting them with flour or fitting them with parchment circles.
- In a large mixing bowl, combine the boxed white cake mix with the strawberry gelatin powder. Whisk to blend the dry ingredients evenly.
- To the dry mixture, add the eggs, milk, vegetable oil, sour cream, mashed strawberries, and vanilla extract. Using an electric mixer on medium speed, beat for approximately 2 minutes until the batter is velvety and uniformly mixed.
- Evenly pour the prepared batter into the two pans, smoothing the surface with a spatula.
- Place in the oven and bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the baked cakes to cool in the pans for 10 minutes. Carefully remove them and set on wire racks to cool fully before assembling.
- Meanwhile, prepare the strawberry frosting. In a separate large bowl, beat the softened butter until it becomes pale and fluffy.
- Gradually incorporate the powdered sugar, adding one cup at a time and beating well between each addition.
- Stir in the pureed strawberries, vanilla extract, and a pinch of salt. Mix until the frosting is smooth. If the consistency is too runny, add a bit more powdered sugar. If it’s too stiff, adjust with a splash of milk.
- Once cakes are completely cooled, trim the domed tops if necessary. Position one cake round on a serving plate and spread an even layer of frosting across the top.
- Gently place the second cake layer on top, then frost the entire cake—top and sides—until evenly covered.
- Optional: Adorn with fresh strawberry slices or whole berries for decoration. Refrigerate for 20 to 30 minutes before slicing to achieve clean, sharp cuts.
