Pink Lemonade Cake — Lemon Cake with Strawberry Buttercream (From Scratch)

If you've been around here for a while, you already know I have a soft spot for my Lemon Layer Cake with Lemon Cream Cheese Frosting. It's bright, fluffy, and packed with real lemon flavor — and honestly, it's one of my favorites. But when the weather starts warming up and my brain shifts into full summer mode, I couldn't help but wonder… what if we made it pink?

That's exactly how this Pink Lemonade Cake was born. Same gorgeous lemon cake base, but layered with fresh strawberry puree and covered in the most beautiful strawberry buttercream. Topped with fresh lemon wedges and pink chocolate candy melts, she is giving everything summer has to offer and then some.

This one is a showstopper for backyard parties, baby showers, birthdays, or honestly any occasion that deserves something a little extra. Let's get into it!

Why This Pink Lemonade Cake Works

Pink lemonade cake sounds like it should be a novelty — something pretty to look at that doesn't quite deliver on flavor. This one delivers. Here's what makes it different from every other pink cake on the internet:

Oil and butter together for the best of both worlds. Pure butter cakes have incredible flavor but can dry out quickly. Pure oil cakes stay moist for days but taste flat. This recipe uses both — butter for richness and depth, oil for the kind of moisture that's still there on day three. The combination gives you a cake that tastes homemade in the best possible way and holds up beautifully for parties where it needs to sit out for a while.

Sour cream for a tight, tender crumb. Sour cream is the secret weapon in this batter. Its fat content adds richness and its acidity reacts with the baking soda to produce a finer, more delicate crumb than milk alone ever could. It's also what keeps the cake tasting fresh rather than stale — sour cream locks in moisture in a way that most bakers don't realize until they try it.

Real lemon zest and extract — not artificial flavor. The lemon in this cake comes from a full tablespoon of fresh lemon zest and lemon extract working together. The zest carries the essential oils from the rind — that's where the bright, natural lemon flavor lives — and the extract amplifies it into something unmistakable. You taste actual lemon, not the artificial punch of a boxed mix.

Homemade strawberry puree — not food coloring. The pink in this cake isn't from a bottle of dye. It comes from real strawberries cooked down into a sweet, jammy puree that goes both between the layers and into the buttercream. That's real strawberry flavor woven through every single element of the cake — not just a color choice but a flavor decision that makes this cake taste as good as it looks.

Strawberry puree in the buttercream instead of extract. Most strawberry buttercreams use artificial strawberry extract which tastes candy-like and flat. This one uses 3 tablespoons of the same homemade puree from the filling — the real fruit flavor comes through in every bite of frosting and pairs with the lemon cake in a way that artificial extract never could.

Four layers instead of two. Slicing each baked layer in half gives you four thinner layers with more frosting between each one. More frosting-to-cake ratio in every slice, a more dramatic reveal when you cut it, and a cake that looks genuinely impressive on a table without being any harder to make than a standard two-layer cake.

The pink drip finish. Melted pink chocolate candy melts dripped over the top edge of the frosted cake take it from homemade to bakery-level in under five minutes. No special skills required — just melted candy melts in a piping bag or squeeze bottle, a slow drip around the edge, and confidence. The color contrast against the pink buttercream is stunning.

Instructions

Make the Lemon Cake:

1. Preheat your oven to 325°F and generously spray two 8-inch round cake pans with non-stick baking spray.

2. In a mixing bowl, beat the oil and butter on high speed for 2 minutes. Slowly add the sugar and continue beating on high for 4-5 minutes until the mixture is very pale yellow and fluffy.

3. Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl as needed.

4. Lower the mixer speed and gradually add the flour in two increments, then add the baking powder, salt, and baking soda. Be careful not to over-mix.

5. Add the sour cream, milk, lemon zest, lemon extract, and vanilla extract. Mix until just combined, then turn off the mixer.

6. Evenly distribute the batter between the prepared pans. Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean. Start checking at 27 minutes to avoid overbaking.

7. Let the cakes rest in the pans for 10-15 minutes, then invert onto a cooling rack until fully cooled.

   
   

Make the Strawberry Puree:

1. Combine strawberries, sugar, and lemon juice in a small saucepan over medium heat.

2. Cook down for 8-10 minutes, stirring occasionally, until the strawberries have broken down and the mixture has thickened slightly.

3. Remove from heat and let cool completely. You'll use some of this in your buttercream and some between the layers.

   
   

Make the Strawberry Buttercream:

1. Beat the butter on high speed until light and fluffy, about 10 minutes.

2. Reduce speed and slowly add the powdered sugar, one cup at a time.

3. Add the strawberry puree, vanilla extract, and salt. Beat on high until fully combined and fluffy.

4. If the frosting is too thick, add heavy cream one tablespoon at a time until you reach your desired consistency. If it's too soft, add a little more powdered sugar.

5. If you want a deeper pink color, add a small amount of pink or red gel food coloring.

Assemble the Cake:

1. Level the cooled cakes if needed, then slice each layer in half horizontally so you have four layers total.

2. Place the first layer on your cake board or plate. Spread a thin layer of strawberry buttercream, then spoon a layer of strawberry puree on top.

3. Repeat with each layer, finishing with the final cake layer on top.

4. Apply a thin crumb coat of strawberry buttercream and refrigerate for 15-20 minutes to set.

5. Frost the outside of the cake with the remaining buttercream and smooth to your liking.

6. Drizzle melted pink chocolate candy melts over the top for a drip effect, then arrange fresh lemon wedges and additional buttercream and candy melt decorations on top.

7. Slice, serve, and try not to eat the whole thing in one sitting!

Tips and Tricks

• Room temperature everything. Butter, eggs — all of it. It makes a difference in both the cake texture and the frosting consistency.

• Don't skip the crumb coat. With a pink frosting, you really want that first layer to set before you do your final coat so the crumbs don't show through.

• Puree consistency matters. Make sure your strawberry puree is fully cooled and not too loose before adding it to your buttercream or it will break the frosting.

• Start checking at 27 minutes. Every oven is a little different and you do not want to overbake this cake. A toothpick with a few moist crumbs is perfect.

Pink Lemonade Cake Variations

Strawberry Lemonade Sheet Cake Pour the batter into a greased 9x13 inch pan and bake at 325°F for 35-40 minutes. Spread a thin layer of strawberry puree across the cooled cake before frosting with the strawberry buttercream. Skip the drip and the cake pops — just a clean sheet cake with a gorgeous pink frosting and fresh strawberry garnish. Perfect for feeding a crowd at a summer party with zero stacking stress.

Pink Lemonade Cupcakes Fill lined cupcake tins two-thirds full and bake for 18-22 minutes. Core each cooled cupcake and fill with a teaspoon of chilled strawberry puree before piping the strawberry buttercream on top. A single fresh strawberry on each one makes them as beautiful as they are delicious. Makes approximately 24 cupcakes.

Pink Lemonade Bundt Cake Pour the batter into a well-greased bundt pan and bake at 325°F for 45-55 minutes. Skip the buttercream and drizzle with a simple strawberry glaze — powdered sugar, strawberry puree, and a splash of lemon juice whisked together until pourable. The glaze soaks into the warm cake and creates a pink shell that looks beautiful with zero decorating required.

Raspberry Lemonade Cake Swap the strawberry puree for homemade raspberry filling — same method, same ratios, just raspberries instead of strawberries. The raspberry version is slightly more tart and the color is a deeper, more vibrant pink. Check out the lemon raspberry layer cake on this site for the exact filling recipe.

Frequently Asked Questions

What makes this a pink lemonade cake and not just a strawberry cake? The lemon is the star and the strawberry is the supporting act. The cake base is a genuine lemon cake — full tablespoon of lemon zest, lemon extract, the works. The strawberry comes in through the filling and the buttercream. The combination of bright lemon cake with sweet strawberry frosting is what creates the pink lemonade effect — you taste lemon first and strawberry finishes it. A strawberry cake leads with berry. This one leads with citrus.

Can I use store-bought strawberry jam instead of making the puree? You can but it won't taste as fresh or as vibrant. Store-bought jam is sweeter, thicker, and has a more processed flavor that competes with the lemon rather than complementing it. The homemade puree takes ten minutes and uses just three ingredients — strawberries, sugar, and lemon juice. The difference in flavor is worth every minute. If you do use store-bought, choose a high-quality seedless jam and thin it slightly with fresh lemon juice.

How do I keep my strawberry buttercream from getting runny? Make sure your strawberry puree is completely cooled and not too loose before adding it to the buttercream. Warm or watery puree will break the frosting. Cook the puree until it's thick and jammy — it should coat the back of a spoon. If your buttercream still seems too soft after mixing, refrigerate it for 15-20 minutes and re-whip. Add powdered sugar a tablespoon at a time if it needs more structure.

Do I need pink food coloring? No — the strawberry puree in the buttercream naturally tints it a beautiful pale pink. The food coloring is optional and only needed if you want a deeper, more vibrant color. If you do use it, gel food coloring gives a more intense color with less product than liquid — start with a tiny amount and add more gradually. You can always add more but you can't take it out.

Can I make this cake ahead of time? Yes — this is a great make-ahead cake. Bake the layers up to 2 days ahead, wrap each one tightly in plastic wrap and refrigerate. Make the strawberry puree up to 3 days ahead — store covered in the refrigerator. Make the buttercream up to 1 day ahead — store covered in the refrigerator and re-whip before using. Assemble and frost the day you plan to serve or the day before. The assembled frosted cake keeps covered in the refrigerator for up to 5 days.

Can I use frozen strawberries for the puree? Absolutely — frozen strawberries work just as well as fresh for the puree since they get cooked down anyway. The flavor and color are essentially identical. Save fresh strawberries for garnish where the appearance matters. Frozen strawberries are also available year-round and significantly cheaper than fresh which makes this cake accessible any time of year.

What's the best way to do the candy melt drip? Melt the candy melts according to package instructions until completely smooth and fluid. Let them cool for 2-3 minutes — if they're too hot the drip runs all the way down the sides uncontrollably. If they're too cool they won't drip at all. Test on the back of a spoon first. Pour into a piping bag or squeeze bottle and apply to the edge of the fully chilled frosted cake — start with a small amount and let gravity do the work. A chilled cake is non-negotiable for a controlled drip.

How do I get clean layers when slicing the cake into four? Mark the halfway point around the perimeter of each baked layer with toothpicks before cutting — they act as a guide to keep your knife level. Use a long serrated knife and slice slowly with a gentle sawing motion rather than pressing down. Refrigerate the layers for 30 minutes before slicing if they feel too soft — cold cake is significantly easier to cut cleanly. A turntable helps keep everything level as you cut.
