Ingredients for 7 up cake recipe with coconut pineapple frosting
Bright citrus layers and tropical frosting—this cake tastes like childhood sunshine in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| 7-Up (Citrus Soda) 🥤 | 1 ½ cups | Real soda, not imitation |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 3 whole | Room temperature, beaten |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| Crushed Pineapple (Drained) 🍍 | 1 cup | Packed, no syrup |
| Sweetened Condensed Milk 🥛 | 14 oz | Full-fat for richness |
| Shredded Coconut (Sweetened) 🥥 | 2 cups | Toasted for extra flavor |
| Pineapple Juice 🍍 | ½ cup | Fresh or canned, no sugar added |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for stiff peaks |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth frosting |
The 7-Up is non-negotiable here—real soda, not that powdered junk. Grab a 2-liter at Walmart or Target (they always have it), or your local convenience store. The crushed pineapple should be packed and drained—no syrup, just pure fruit. For the coconut, Trader Joe’s has the best toasted variety, but the regular kind works too. If you’re feeling fancy, toast your own shredded coconut in a dry pan for 3-4 minutes until golden. The condensed milk? Full-fat only—it makes the frosting rich and creamy.
No 7-Up? Sprite or lemon-lime soda works in a pinch, but it won’t be quite the same. Fresh pineapple juice is ideal, but canned no-sugar-added is fine too. Running short on whipping cream? Coconut cream chilled overnight gives a similar texture. For the cake, make sure your butter is room temperature—it should dent when pressed but not be greasy. The frosting can be made a day ahead and stored in the fridge, so you’re not stressing last-minute. Just whip it back up before assembling.
This cake keeps beautifully—3 days at room temperature covered loosely, or 5 days refrigerated. The frosting can be stored separately for up to 1 week in the fridge. For serving, let the cake sit at room temp for 10 minutes—it slices cleaner that way. Leftovers? Freeze individual slices wrapped tightly for up to 1 month. The frosting also freezes well if you’re prepping ahead for a big party.

- Party in a Box: Honestly, this cake is my go-to for birthdays, potlucks, or even just a lazy Sunday. The frosting’s bright and creamy, but it’s not fussy—no piping bags or decorating skills required. Slice it, serve it, and watch people ask for seconds.
- Budget Magic: I make this all the time because it’s cheap and clever. A box of cake mix (or your own mix), a can of 7-Up, and a few dollars for coconut flakes stretch to feed a crowd. Plus, leftovers? They actually taste better the next day—moist, not dry, not sad.
Step-by-step instructions for 7-Up cake with coconut pineapple frosting
Here’s how to bake this nostalgic cake with fluffy layers and that perfect tropical frosting.
👨🍳 Step 1: Mix the Cake Batter
Preheat your oven to 350°F and grease three 9-inch round cake pans (or line with parchment circles). In a large bowl, cream together the 1 cup unsalted butter and 2 cups granulated sugar until light and fluffy—about 3-4 minutes with an electric mixer. You’ll see the mixture nearly double in volume and turn pale.
Add the 3 whole large eggs, one at a time, beating well after each addition. Then mix in the 2 tsp vanilla extract and 1.5 cups 7-Up (Citrus Soda). Sift in the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt, mixing just until combined. Be careful not to overmix—small lumps are fine. Fold in the 1 cup crushed pineapple (drained) using a spatula.
🔥 Step 2: Bake the Layers
Divide the batter evenly among the prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. The cakes should spring back when gently pressed. Let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Here’s the thing—don’t skip the cooling step. Warm cakes will make your frosting slide right off. While they cool, make the filling by combining the 14 oz sweetened condensed milk and 0.5 cup pineapple juice in a saucepan. Heat over medium-low heat, stirring constantly, until smooth and slightly thickened—about 5 minutes. Let it cool completely before assembling.
🥘 Step 3: Assemble the Cake
Place the first cake layer on a serving plate. Spread half of the condensed milk mixture evenly over the top. Sprinkle 1 cup shredded coconut (sweetened) over the filling. Repeat with the second layer, then the remaining filling and coconut. Top with the final cake layer.
For the frosting, beat the 1 cup heavy whipping cream until soft peaks form. Gradually add the 3 cups powdered sugar, mixing until stiff peaks form. Spread this over the top and sides of the cake. Press the remaining 1 cup shredded coconut onto the frosting for that classic tropical look.
⏰ Step 4: Chill and Serve
Refrigerate the cake for at least 2 hours (or up to 24 hours) before serving. This lets the flavors meld and the frosting set properly. When ready to serve, garnish with extra toasted coconut if desired. Each slice should have that perfect balance of moist cake, tangy pineapple, creamy filling, and sweet coconut frosting.
I know it seems like a lot of steps, but trust me—this cake is worth every minute. The 7-Up gives it that signature lightness, while the coconut frosting takes it to tropical heaven. Serve with a scoop of vanilla ice cream for the ultimate treat!
Pro Tips For Making 7 Up Cake Recipe With Coconut Pineapple Frosting
- Chill the Soda First: Pour that 7-Up into the fridge for at least 30 minutes before mixing it into the batter. Cold soda prevents the butter from melting too fast, which keeps your cake tender instead of greasy—trust me, I’ve made this mistake with room-temp soda and regretted it.
- Sift the Flour Twice: Don’t just shake the flour into the bowl—sift it through a fine-mesh strainer before measuring, then sift it again right into the batter. This cuts out lumps and aerates the flour, giving your cake a lighter crumb. I learned this the hard way when my first batch turned out dense as a brick.
- Rotate the Pan: Swap the cake pans halfway through baking—front to back, then back to front. This ensures even browning, especially if your oven runs hot on one side. I used to ignore this and end up with a cake that was golden on one side and pale on the other.
- Whip the Frosting Fast: Beat the coconut pineapple frosting in short bursts—30 seconds on, then scrape the bowl—until it’s fluffy but not buttery. Overmixing turns it into a gloppy mess. If you’re in a rush, use a stand mixer on medium speed and stop as soon as it thickens. Your future self will thank you.
Pro cooking tips for 7 up cake recipe with coconut pineapple frosting
Citrus Soda Magic
The 7-Up in this cake isn’t just flavor—it’s the secret to that signature lightness and tang. Always use real soda, not powdered mix, for authentic taste. I’ve found that room-temperature soda blends better with the batter, so take it out of the fridge 10 minutes before mixing.
If you’re short on time, Sprite or lemon-lime soda works in a pinch, but it won’t have that same citrus complexity. 🥤
Frosting Texture Tips
For the coconut pineapple frosting, cold ingredients are key. Chill your heavy whipping cream and powdered sugar in the fridge for 15 minutes before whipping to prevent melting.
I like to add the pineapple juice to the condensed milk mixture while it’s still warm—this helps emulsify it better for a smoother texture. If your frosting isn’t stiff enough, add 1 tsp more powdered sugar at a time until it holds peaks. 💫
Layering Like a Pro
When assembling, level your cake layers with a serrated knife for even frosting distribution. Spread the condensed milk filling sparingly—too much will cause soggy layers. For extra flair, toast the shredded coconut in a dry pan for 3-4 minutes until golden before pressing it onto the frosting.
This adds crunch and depth of flavor that plain coconut can’t match. 🌴
Baking Time Mastery
Ovens vary, so start checking your cakes at 25 minutes. A toothpick test is your best friend—it should come out clean or with a few moist crumbs. If the tops brown too quickly, tent the pans with foil.
I’ve learned the hard way that overbaking makes the cake dry, so pull them out as soon as they’re done. Let them cool completely before frosting to avoid a melty mess. ⏰
Make-Ahead Secrets
This cake tastes even better the next day! Assemble it 24 hours ahead and refrigerate uncovered. The flavors meld beautifully, and the frosting sets perfectly. For the frosting alone, whip it up a day in advance and store it in an airtight container in the fridge.
Rewhip it briefly before using—it’ll be just as fluffy. 💡
Tropical Garnish Upgrade
Take your cake to the next level with edible flowers or pineapple slices on top. For a festive touch, pipe the frosting into swirls with a pastry bag fitted with a star tip.
If you’re feeling adventurous, add a sprinkle of crushed macadamia nuts for a gourmet twist. The key is balance—don’t overdo it, or the cake’s natural flavors will get lost. ✨

Frequently asked questions
Can I substitute 7-Up with another soda?
The 7-Up is key for that signature citrus flavor and light texture. For a similar taste, use Sprite or lemon-lime soda—just know it won’t be identical. Avoid cola or orange sodas, as they’ll change the flavor profile completely. If you’re in a bind, even lemon-lime juice mixed with a little water can work, but the texture won’t be as light.
How do I keep the cake layers from getting soggy?
Always let the cake layers cool completely before frosting—this prevents melting. Use a serrated knife to level the tops evenly, and spread the condensed milk filling sparingly. If your cake still feels too moist, chill it for 30 minutes in the fridge before adding the final frosting layer.
Can I make this cake in a different pan size?
Yes, but adjust baking times carefully. For 8-inch pans, bake 20-25 minutes instead of 25-30. If using a tube pan, reduce oven temp to 325°F and bake 35-40 minutes. The key is checking for doneness with a toothpick—it should come out clean or with a few crumbs.
Why did my frosting turn grainy?
Grainy frosting usually means the ingredients weren’t cold enough or the sugar wasn’t sifted. Chill your powdered sugar and whipping cream for 15 minutes before whipping, and sift the sugar thoroughly. If it’s already grainy, strain it through a fine-mesh sieve before adding to the cream.
How can I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob’s Red Mill). Add 1 tsp xanthan gum to help bind the cake. For the frosting, use gluten-free powdered sugar and ensure your shredded coconut is certified gluten-free. The texture will be slightly denser, but the flavors will still shine!
