Effortless Mango Lassi Cake

Featured in: End Your Meal on a High Note

Effortless Mango Lassi Cake is a fun twist on classic desserts from Mexico and Pakistan. You start with a fluffy sponge, poke loads of holes, then pour in a mix of three milks blended with sweet mango, smooth yogurt, and a bit of cardamom for that lassi kick. Overnight, it turns extra moist and packed with flavor. Once it's chilled, add a rich cloud of mango whipped cream and scatter chopped mangoes all over. This one’s cool, refreshing, and always steals the show at picnics and parties. A dash of cardamom makes every bite smell and taste special.

Golden sunlight splashes through juicy mangoes and takes tres leches cake to a whole new level, packing every bite with sweet, sunny, tropical vibes. This wild combo brings together the rich milky cake folks love in Latin America and the chilled, creamy mango lassi that keeps India cool in the heat. Each bite? Super soft, ultra-moist, bursting with mango flavor from bottom to fluffy top.

This came together one blazing summer day hanging out with friends from all over. Mangoes on my counter begged for something cool and different. When I finally plated this up, everyone just stopped mid-chat and melted into pure mango cake bliss. Even my friend’s grandma, a stickler for the old ways, suddenly wanted all the details before she left—which totally made my day.

Flavorful Ingredients

  • Alphonso mangoes: Seriously sweet and smell amazing, but ripe Ataulfo or Kent work in a pinch.
  • Thick Greek yogurt: Adds creamy, tangy punch like a proper lassi. Keep away from the low-fat stuff.
  • Cardamom powder: Brings a gentle, floral kick that boosts all that mango goodness without taking over.
  • Extra-fine sugar: Melts right in while mixing, making everything smooth and dreamy—both the cake and topping.
  • Real vanilla extract: Rounds out the fruity vibes with a cozy note. Make sure it’s the real deal, not the fake stuff.
  • Cornstarch: Gives that soft, spongy finish and help the cake soak up all the milky mango mix.

How To Bake It

Build a light sponge first
Start with separating the eggs—cold eggs work best here since there’s less yolk breakage. Whip up those egg whites til frothy with a squeaky clean beater, then stall for a sec so you can slowly add sugar and watch those peaks get stiff and glossy. Next, beat the yolks and the rest of the sugar until it’s pale and super thick. Sift the dry stuff together three times to keep things fluffy.
Fold for that cloud feel
Gently fold the whites into your yolks with a wide spatula. Go slow—big downward, then a soft swirl. Stop when it all looks even, you don’t want to squash out those bubbles. Pour into your pan and skip the urge to smooth it out.
Oven time
Bake in the middle, oven preheated and ready. Don’t peek for the first 20 minutes, and check for a clean tester (not soupy batter, but just moist) in the center. Once done, leave it in the pan for 10 minutes, then tip out onto a rack to cool off.
Mango magic time
Peel, chop and cube your best mangoes—look for that gentle squeeze and sweet smell. Toss with yogurt and cardamom, whiz up until velvety, then strain out any tough bits. Save some for the topping, the rest’s for soaking with the milk mix.
Soak it up
Poke cooled cake all over (every half inch or so) using a skewer. Pour the milk in three rounds, letting it soak in each time before adding more. Wrap it up and chill in the fridge overnight—trust me, it’s worth it.
Pillowy top layer
Get your bowl and beaters icy cold in the freezer for a quick blast. Whip up the cream until it’s just holding peaks, then stream in that mango yogurt you saved. Keep whipping until it’s firm but smooth—not chunky. Pile on a thick layer with an offset spatula.

My grandma always said you can’t rush a milk-soaked cake. She was right! When you pour in the mango milk mix a little at a time, giving it space to soak, the texture turns out just right. I remember one hurried night when I dumped it all in—everyone liked it, but it didn’t have that incredible evenness that makes it unforgettable.

Temperature Tips

Getting the temps right changes everything. Separate your eggs fresh from the fridge—they break cleaner. But for the fluffiest meringue, let them warm up to room temp, about half an hour. As for that whipped cream? Go straight from the coldest part of your fridge, and toss the bowl and beaters in the freezer. Let your cake cool completely before pouring in the milk mix, or it’ll get soggy and flat.

Serving Ideas

Slice and serve with mango fans on each piece, and dust just a tad of cardamom up top for a pretty finish. Mint sprigs make things pop and add a little herby freshness. On special days, pour out mini mango lassis in glasses, maybe dress them with edible flowers. In the afternoon, pair cake with hot masala chai—the spices warm you up while the cake cools you down.

New Twists To Try

Switch up your fruit and add passion fruit pulp to the mango blend—it’ll really punch up the tropical vibes. Going dairy free? Swap in coconut yogurt and coconut cream for the yogurt and whipping cream. Stick extra mango cubes between cake and topping for more bite. A ring of crushed pistachios around the sides gives color, crunch, and a little luxury.

Storage Hacks

Keep leftovers in the fridge, pressed tight with plastic wrap on the surface so they stay nice and moist. You can even freeze single slices—wrap them first in plastic, then in foil, and pop on the topping fresh after thawing. When serving straight from the fridge, give slices 15 minutes at room temp so all those flavors wake up again.

This dessert adventure taught me great fusion happens where traditions meet. When Latin American soul food and Indian comfort drinks blend, there’s something magical you can actually taste. Every bite feels like catching a bit of summer at its sweetest. It proves new ideas and a love of good ingredients can turn simple favorites into something you’ll remember long after the season’s gone.

Frequently Asked Questions

→ Can I use canned mango pulp instead of fresh mangoes?
Absolutely! Canned mango pulp gets the job done. Use about 1½ cups when making the lassi mix. Just check the sweetness because canned versions can be sugary. Still, nothing beats fresh mango chunks for topping—they give the best look and bite.
→ How far in advance can I make this Mango Lassi Tres Leches Cake?
You’re good to prep the cake up to two days before you need it. Actually, letting it chill overnight deepens the flavors even more. Hold off on the whipped topping and fruit until the same day you serve, so everything looks fresh.
→ Can I make this cake gluten-free?
Yep, just swap the all-purpose flour for a gluten-free mix (pick one with xanthan gum for best results). The other stuff in this cake already fits gluten-free needs.
→ What can I substitute for cardamom if I don't have any?
No cardamom? Toss in a little cinnamon or maybe a drip of vanilla. The taste will shift a bit since cardamom is what usually gives that lassi flavor, but your cake’s still going to rock.
→ Why does my milk mixture take so long to absorb?
If the milk’s taking a while to sink in, either your sauce is too thick or the cake’s a bit heavy. Make sure you poke nice, deep holes with a fork, and thin out the milk with a bit more plain milk if needed. Sometimes, patience is all you need—let it sit and it’ll all soak through.
→ Can I freeze leftovers of this cake?
You can freeze the cake part, just know the whipped cream layer gets weird after freezing. If you have to stash extras, freeze just the cake and add fresh whipped cream after defrosting it in the fridge overnight.

09 ¼ teaspoon cream of tartar

→ Mango Lassi Ingredients

10 1½ cups diced ripe mango (frozen or fresh are fine)
11 ½ cup yogurt (plain and full-fat preferred)
12 ¾ cup milk of your choice
13 2-4 tablespoons sugar, depending on how sweet your mango tastes
14 A pinch of cardamom powder for fragrance

→ Three Milk Mix

15 ½ cup sweetened condensed milk (6 ounces)
16 6 ounces evaporated milk (this equals ¾ cup)
17 ½ cup regular milk
18 Half of your blended mango lassi

→ Whipped Mango Topping

19 1½ cups fridge-cold heavy cream for whipping
20 The rest of your mango lassi blend

22 Optional plain whipped cream for piping décor

Instructions

Step 01

Heat your oven to 350°F and line a rectangle 9×13-inch baking dish with parchment, leaving the edges a bit longer so you can lift the cake out later.

Step 02

Grab a large mixing bowl and combine the yolks, ½ cup sugar, salt, and vanilla. Whisk for 1-2 minutes until it's smooth, bubbly, and light yellow. Stir the milk in gently. Sift in flour, baking powder, and cornstarch, then mix just until it all comes together. Try not to overmix—it can make your cake dense.

Step 03

In a clean bowl with zero grease (important!), beat the whites with cream of tartar using an electric mixer. First, beat on medium until bubbles form. Slowly sprinkle in ¼ cup sugar while whipping until it creates stiff, glossy peaks when you lift the mixer.

Step 04

Take one-third of your airy egg whites and fold it carefully into the yolk mix—it'll lighten up the texture. Work gently. Then, fold in the rest of the whites the same way. Pour this fluffy batter into your lined pan, smooth the top, and bake for about 15 minutes. It's done when a toothpick inserted into the center comes out with no wet batter.

Step 05

As your cake cools off, grab a blender and toss in your mango chunks, yogurt, milk, sugar, and cardamom. Blend until creamy. Strain this mixture with a mesh sieve for extra smoothness. Taste-test: it should be sweet with a light cardamom aroma. Split into two portions; half you'll use now, half for later.

Step 06

Mix together condensed milk, evaporated milk, regular milk, and the first half of your mango lassi until it's smooth. It’ll look like thinned-down custard or slightly melted ice cream. If it feels too heavy, splash in a bit more milk and stir.

Step 07

Keep the cake in its pan and poke holes all over it (use a skewer or fork). Slowly pour in a bit of the milk mixture and let the sponge absorb it. Wait 20 minutes and repeat in small amounts until every drop is used up. You can refrigerate now and chill it for at least 2 hours—or keep it overnight for the best flavor.

Step 08

When you're ready to dress the cake, whisk your cold heavy cream in a chilled bowl until it thickens. Gradually add the remaining blended lassi while whipping, and stop when the cream has whipped peaks. It should look fluffy but smooth.

Step 09

Spread that gorgeous mango cream across the top of your chilled cake. If you want to get a bit fancy, pipe plain whipped cream as decoration. Pile fresh mango chunks generously on top. Keep cold and dig in whenever you're ready!

Notes

  1. Letting it chill overnight enhances both the flavor and texture balance.
  2. If your mangoes are not very sweet, just bump the sugar up a little in your lassi.
  3. Cardamom brings a lovely aroma and subtle flavor. Try not to skip it!
  4. The cake stays fresh in the fridge for up to three days.
