Transform ordinary lemon cake mix into an extraordinary dessert bursting with bright citrus flavor. This perfectly balanced cake combines sweet and tart notes, finished with a silky cream cheese frosting. The secret lies in using frozen lemonade concentrate to infuse intense citrus flavor throughout every layer.
After experimenting with various lemon cake recipes, this version stands out for its intense citrus flavor and foolproof preparation method.
Essential Ingredients Selection
- Premium lemon cake mix (15.25 ounces): Duncan Hines or Betty Crocker preferred for consistency. The mix should smell fresh and lemony, not stale.
- Large eggs (3): Must be grade A or AA, precisely room temperature (68-72°F). Shells should be clean and uncracked.
- Vegetable oil (½ cup): Use fresh, newly opened canola or pure vegetable oil. Avoid olive or coconut oil.
- Room temperature water (1 cup): Filtered or spring water at exactly 70°F to prevent metallic taste.
- Frozen lemonade concentrate (1 cup for cake + 3 tablespoons for frosting): Must be premium brand like Minute Maid or Simply Lemonade, thawed completely.
- Pure powdered sugar (1 cup for soaking + 3-4 cups for frosting): Use fresh, sifted pure cane sugar for best texture.
- Full-fat cream cheese (8 ounces): Philadelphia brand original, softened for 1 hour.
- Unsalted butter (½ cup): European-style with 82% butterfat, softened for 45 minutes.
- Fine sea salt (1 precise pinch): Diamond Crystal brand, fine grain.
- Optional garnish: Fresh lemon zest, candied lemon slices, or edible flowers.
Creating Perfect Lemonade Cake
- Cake Base Preparation
- Ensure all ingredients are at room temperature (68-72°F). Preheat oven to 350°F with rack centered. Prepare 9x13-inch pan with parchment, leaving overhang for easy removal.
- Mixing Method
- Combine cake mix, eggs, oil, and filtered water in stand mixer with paddle attachment. Beat at medium speed for exactly 2 minutes until smooth.
- Baking Process
- Pour batter into prepared pan, smoothing top. Tap pan firmly on counter three times to remove air bubbles. Bake 28-33 minutes until a toothpick comes out with a few moist crumbs.
- Soaking Stage
- While cake is still hot (around 180°F), use fork to create holes every ½ inch. Whisk 1 cup thawed lemonade concentrate with sifted powdered sugar until smooth.
- Flavor Infusion
- Pour lemonade mixture evenly over hot cake, ensuring it soaks into all holes.
- Frosting Creation
- Beat softened cream cheese in stand mixer until smooth. Add butter, beating until combined. Gradually incorporate sifted powdered sugar, lemonade concentrate, and salt.
- Final Assembly
- Once cake reaches room temperature, spread frosting in swooping motions using offset spatula. Create decorative swirls if desired.

My grandmother taught me that the secret to perfect soaking lies in the temperature of both cake and liquid. Too cool, and it won't absorb properly.
Perfect Serving Solutions
Chill cake for minimum 4 hours, ideally overnight. Remove from refrigerator 20 minutes before serving. Use a serrated knife dipped in hot water for clean slices. Present on a chilled platter for summer gatherings. Individual slices look elegant on dessert plates with fresh mint leaves.
Creative Variations
Transform this classic with a variety of refreshing flavors. A pink lemonade version made with pink lemonade concentrate adds a slightly sweeter, tangy twist. For a raspberry lemonade variation, mix in half raspberry purée to bring a bold, tart flavor. A strawberry lemonade take features fresh macerated berries layered throughout, adding natural sweetness and a vibrant touch.
Storage Success
For an unfrosted cake, keep it tightly wrapped at room temperature for up to 24 hours. In the refrigerator, store it in an airtight container for up to five days. For longer storage, freeze it for up to three months by double-wrapping in plastic and foil. A frosted cake should always be refrigerated in a covered container for up to five days. If freezing, wrap individual slices and store them for up to one month. Due to the cream cheese frosting, never leave it at room temperature.
Make-Ahead Instructions
- Cake can be baked and soaked 3 days ahead
- Frosting can be made 2 days ahead, stored separately
- Assemble within 4 hours of serving for best presentation
Through years of perfecting this recipe, I've learned that patience during the chilling process creates the best texture. The way the lemonade concentrate infuses through each layer reminds me of summer afternoons spent making lemonade with my children.
