A soft, ultra-pink layer cake built from boxed mix and real strawberry puree — this version balances convenience and fresh fruit flavor so well it’s become my go-to for birthdays, potlucks, and last-minute celebrations. The trick is using frozen strawberries in syrup for consistent sweetness and a vibrant color; the cream cheese frosting with extra strawberry puree keeps the whole thing bright and slightly tangy.
Why you’ll love this dish
This is the kind of cake that looks like you spent hours on it but comes together quickly. Using a white cake mix plus strawberry gelatin gives reliable rise and texture, while the thawed strawberries add real fruit flavor that boxed mixes alone can’t deliver. It’s approachable for novice bakers and customizable for home cooks who want to elevate a shortcut.
“I made this for a family brunch and everyone asked for the recipe—moist layers and exactly the kind of strawberry flavor we wanted.” — a satisfied baker
Because it’s fast and crowd-pleasing, it’s perfect for weekday celebrations and weekend brunch menus. If you’re planning a brunch spread, pair it with easy breakfast classics like fluffy flapjacks — the best pancakes recipe for a cheerful, coordinated table.
How this recipe comes together
Start by mixing the cake base (white cake mix + strawberry gelatin) with pureed strawberries and a few wet ingredients. Bake two 9-inch layers until a toothpick comes out clean, then cool completely. For the frosting, beat butter and cream cheese until smooth, add some of the strawberry puree and extract, then blend in confectioners’ sugar until silky. Stack, crumb-coat if desired, and finish with a final smooth coat and fresh strawberries on top.
Quick timeline:
- 15–20 minutes prep (excluding cooling)
- 20 minutes bake time
- Cooling + frosting: 1–2 hours (mostly hands-off)
What you’ll need
- 1 (18.25-ounce) box white cake mix
- 1 (3-ounce) box strawberry-flavored instant gelatin (e.g., Jell-O)
- 1 (15-ounce) package frozen strawberries in syrup, thawed and pureed (reserve 1/4 cup for frosting)
- 4 large eggs (room temperature helps lift)
- 1/2 cup vegetable oil
- 1/4 cup water
- 1/4 cup butter, softened (for frosting)
- 1 (8-ounce) package cream cheese, softened (for frosting)
- 1/2 teaspoon strawberry extract (optional but boosts flavor)
- 7 cups confectioners’ sugar (adjust for desired frosting sweetness/texture)
- Freshly sliced strawberries for garnish (optional)
Ingredient notes:
- If your strawberry puree is very sweet because of the syrup, you can reduce the confectioners’ sugar slightly in the frosting.
- Fresh strawberries can be used instead of frozen; see FAQs for details.
- Strawberry extract is optional, but it deepens the strawberry note without extra moisture.
Step-by-step instructions
- Preheat the oven to 350°F (175°C). Lightly grease two 9-inch round cake pans and line the bottoms with parchment if you like.
- In a large bowl, whisk the white cake mix and the strawberry gelatin together to combine.
- Add the pureed strawberries, eggs, vegetable oil, and water to the dry mix. Beat on medium speed with an electric mixer until smooth and uniform. Scrape the bowl once so everything is incorporated.
- Divide the batter evenly between the prepared pans. Smooth the tops with a spatula.
- Bake for about 20 minutes, or until a wooden pick comes out clean from the center. Ovens vary, so begin checking at 18 minutes.
- Let the cakes cool in the pans for 10 minutes. Run a knife around the edges, invert them onto wire racks, and cool completely.
- For the frosting: In a large bowl, beat the softened butter and cream cheese on medium speed until creamy and lump-free.
- Beat in 1/4 cup of the reserved strawberry puree and the 1/2 teaspoon strawberry extract. Gradually add the confectioners’ sugar, about 1 cup at a time, beating until smooth and spreadable. Stop when you reach your preferred sweetness and thickness.
- If needed, chill the frosting briefly (10–15 minutes) to firm it before spreading.
- Place one cooled cake layer on a serving plate. Spread an even layer of frosting, top with the second layer, and frost the top and sides. Garnish with fresh sliced strawberries if desired.
Best ways to enjoy it
Serve slices slightly chilled or at cool room temperature. The cream cheese frosting holds up well in cooler conditions; if left out for longer events (over 2 hours), keep the cake in a shaded area or slice as needed and refrigerate the rest. For drink pairings, a warm mug of Milky Cocoa Indulgence — the best homemade hot cocoa ever or a lightly brewed green tea balances the cake’s sweetness beautifully.
Plating ideas:
- Add a drizzle of reduced strawberry syrup and a sprig of mint for contrast.
- Serve with a scoop of vanilla bean ice cream for an indulgent dessert.
- For brunch, pair with simple fruit salad and sparkling water.
Storage and reheating tips
- Refrigeration: Because the frosting contains cream cheese, store the cake in the refrigerator. Covered (cake keeper or plastic wrap) it will keep 3–4 days.
- Freezing: You can freeze unfrosted layers wrapped tightly in plastic and foil for up to 2 months. Thaw overnight in the refrigerator before frosting. Built and frosted, wrap the cake well and freeze for up to 1 month; thaw in the fridge before serving.
- Serving from chilled: Remove the cake from the fridge 20–30 minutes before serving for a softer mouthfeel.
- Safety note: Do not leave cream cheese–frosted cake at room temperature longer than 2 hours to avoid temperature-abuse risk.
Pro chef tips
- Puree texture: If you prefer a perfectly smooth crumb and frosting color, press the thawed strawberries through a fine mesh sieve to remove seeds and lumps.
- Balance moisture: Frozen strawberries in syrup add water. If your batter seems runnier than expected, reduce the 1/4 cup water slightly.
- Even layers: Weigh batter into the pans for perfectly even layers.
- Prevent domes: Bake on a middle rack and rotate pans halfway through baking if your oven has hot spots.
- Crumb coat: Apply a thin crumb coat (a light layer of frosting), chill 15 minutes, then finish with a final coat for neat sides.
- Room-temp ingredients: Use room-temperature eggs, butter, and cream cheese for a lump-free frosting and better rise in the cake.
Creative twists
- Lemon-strawberry: Add 1 tsp lemon zest to the batter and 1/2 tsp lemon juice to the frosting for brightness.
- Chocolate-strawberry: Add 1/4 cup cocoa to the cake mix (reduce flour by the same amount if needed) and pair with a strawberry cream cheese swirl.
- Gluten-free: Use a gluten-free white cake mix and check gelatin brand for gluten-free labeling.
- Vegan option: Use a vegan white cake mix, flax eggs (1 tbsp ground flax + 3 tbsp water per egg), and vegan cream cheese; note texture and flavor will differ.
- Cupcake format: Bake in 12–14 minutes at the same temp for perfect strawberry cupcakes.
Common questions
Q: Can I use fresh strawberries instead of frozen in syrup?
A: Yes. Use ripe fresh strawberries, pureed. Because fresh berries aren’t sitting in syrup, you may need to add 1–2 tbsp sugar to the batter if your berries are not very sweet. Fresh puree tends to be less watery than syrup-packed berries.
Q: Do I have to use strawberry gelatin?
A: The instant gelatin amplifies color, flavor, and sets the crumb slightly. You can omit it, but expect a paler color and a slightly looser crumb. If avoiding gelatin for dietary reasons, consider a small amount of natural thickener (like a little extra sifted powdered sugar) and increase strawberry puree concentration for flavor.
Q: How far ahead can I make the cake?
A: You can bake the layers 1–2 days ahead and keep them wrapped in the fridge. Freeze layers up to 2 months if you need longer storage. Frosted cakes are best eaten within 3–4 days refrigerated.
Q: Can I reduce the sugar in the frosting?
A: Yes. Start with 5 cups of confectioners’ sugar and add more to reach the thickness you want. Remember the strawberry puree will add sweetness, so taste as you go.
Q: My frosting is runny — how do I fix it?
A: Chill the bowl of frosting for 10–20 minutes and beat again. If still thin, add 1/2 cup more confectioners’ sugar at a time until it firms to spreadable consistency.
