When I say this mango cake recipe is pure sunshine on a plate, I mean it. The sponge is light and airy, the mango jam adds a sweet-tart punch, and the diplomat cream? Honestly, it's silky and luscious in the best way.
This is the cake I'd make for a spring birthday, a summer barbecue, or when I just want something that feels a little tropical at home. The best part? It's not overly complicated, and you can even swap in store-bought whipped topping if you want to save time.

Why you'll love this mango cake recipe
- It has layers of fluffy chiffon-style sponge, homemade mango jam, and a dreamy mango diplomat cream.
- The recipe is flexible - fresh or frozen mangoes both work well.
- It looks fancy but doesn't require special equipment.
- You can prep parts of it ahead of time to make assembly a breeze.
Ingredients you'll need
Here's everything you'll want to gather before starting:
- Butter - I like salted butter, but unsalted or dairy-free works too.
- Flour - all-purpose flour is my go-to. Self-rising flour works if you omit the baking powder.
- Baking powder - for lift.
- Sugar - granulated, used in the cake, cream, and jam.
- Milk - I use 2% milk, but any kind (even dairy-free) works.
- Eggs - large, at room temp. Egg yolks go into the custard, and the whites into the cake.
- Heavy cream - 35-45% fat, or swap with cool whip for a shortcut.
- Gelatin - to stabilize the cream. Powdered works best.
- Mango - ripe fresh mangoes or frozen (no need to thaw).
- Lime - juice for the jam and the sponge.
Step-by-step instructions for making mango cake
Step 1: Make the mango jam
Cook mango chunks, sugar, and lime juice until bubbling, then simmer about 15 minutes until soft and thick. Leave it chunky or blend and strain if you prefer it smooth.
Step 2: Prepare the custard
Cook egg yolks, sugar, and butter until thick like lemon curd. Cover and let it cool completely.
Step 3: Whip the egg whites
Beat egg whites with lime juice and sugar until stiff peaks form.
Step 4: Add yolks and vanilla
Mix in the egg yolks, oil, and vanilla just until combined.
Step 5: Add dry ingredients and milk
Sift in flour and baking powder, then slowly stream in milk. Mix just until combined.
Step 6: Bake the cakes
Divide batter into two greased 8-inch pans. Bake until puffed, then let cool - they'll shrink slightly as they settle.
Step 7: Make the diplomat cream
Mix cooled custard with mango jam.
Step 8: Fold in whipped cream
Whip heavy cream, fold a third into the custard with dissolved gelatin, then fold everything back into the whipped cream.
Step 9: Layer the cake
Spread jam and cream on one cake layer. Chill for 15-30 minutes so it sets.
Step 10: Finish and serve
Place the second cake layer on top, smooth the edges, and refrigerate for at least 1-2 hours (overnight is even better). Dust with powdered sugar and top with mango chunks before serving.
Tips for success
- Use a digital scale for flour - it makes a big difference.
- If your mangoes aren't very sweet, add an extra tablespoon of sugar to the jam.
- Freeze egg whites you don't need for later use in meringues or macarons.
- If you're short on time, use store-bought whipped topping and skip the gelatin step.
Serving and storing
- Serving: Best served chilled with extra fresh mango on top.
- Storing: Keep in the fridge, covered, for up to 3 days.
- Freezing: You can freeze cake layers (without cream) for up to 2 months.
FAQ

Yes, make the cake layers and jam a day before, then assemble the next day.
