Heat oven to 375 degrees. Butter a 9-by-13-inch cake pan and dust with flour.
Prepare the cake: In the bowl of a stand mixer fitted with the whisk attachment, whip the egg whites with the cream of tartar on medium-high until soft peaks form, about 1 minute. Gradually add the sugar, whipping as you go, until fluffy with firm peaks, about 5 minutes.
In a small bowl, whisk together the flour and baking powder. In a medium bowl, whisk together the egg yolks, whole milk and vanilla until well combined. With the mixer running on medium speed, gradually add the wet ingredients to the whipped whites until well combined, stopping and scraping the bowl as necessary. Gradually add the dry ingredients until well combined, scraping the bowl as necessary.
Scrape the batter into the prepared pan, then spread evenly. Bake for 18 minutes, then rotate the pan and continue baking for another 8 to 10 minutes, until the top is golden brown. A toothpick inserted into the center should come out clean.
Remove the cake from the oven and let cool in the pan until slightly warmer than room temperature, about 30 minutes. Refrigerate the cake, still in the pan and uncovered, while you make the tres leches mixture.
Make the tres leches: In a small saucepan, warm the whole milk, evaporated milk and condensed milk over medium heat. Stir occasionally until just shy of simmering, steaming but not bubbling, 10 to 15 minutes. Whisk in the tea powder. Take the saucepan off the heat and let the tea steep for 10 minutes. (It will turn orange.) Using a fine-mesh sieve or tea strainer, strain into a liquid measuring cup or medium bowl.
Take the cake out of the refrigerator. Using a fork, poke holes all across the surface of the cake — the more holes the better — as close together as possible. With the cake still in the pan, cut it into 12 even pieces. (It will be more difficult to cut later, once the tres leches mixture has soaked through.)
Carefully pour the warm tres leches mixture slowly and evenly over the cake, pausing as necessary to let the cake absorb the mixture. The cake should be fully soaked through the center; the white of the crumb should not be visible. Cover the cake with plastic wrap and refrigerate overnight or for a minimum of 3 hours.
Just before serving, make the whipped cream: Combine the heavy cream, sour cream, sugar and vanilla extract in the bowl of a stand mixer. Whip on high speed until the cream doubles in volume and forms stiff peaks, about 1 minute.
When ready to serve, take the cake out of the refrigerator. Transfer each slice to a separate plate. (Leftovers can be refrigerated for up to 3 days.) Using a spatula, spread the whipped cream on top of each slice, or pipe it from a pastry bag. Scatter with the toasted coconut flakes until the whipped cream is covered completely. Finely grate lime zest directly over each slice. Serve cold: The cake should melt in your mouth, with a texture close to ice cream.
This is beyond tasty. The only difficulty was having patience to let it soak before devouring
What a brilliant idea. I've always liked the concept of tres leches cakes, but in practice they're invariably so supersweet that I find them cloying. Cutting all that sweetness with the astringency of tea seems like a tremendous idea. But before investing in the Thai powder, I think I'll experiment by heating the milk and steeping black tea in it. This might result in an unwelcome color, but I'll risk it.
The Wangderm Thai tea contains artificial color. Is there another similar product without this?
I made this for my husband’s birthday (he’s a huge fan of all thing tres leches). This cake blew his socks off! I used ChaTraMue brand tea; it has a little sugar, but I cut the added sugar by 1/3 for baked good recipes, so it didn’t much matter. This cake is a fair amount of process, but worth it. Since it was my first go at making it, aside from cutting sugar, I limited deviation. To the dry mix, added a pinch of cinnamon, cardamom, mace, 1/2 tsp vanilla bean, and 1/2tsp salt to punch it up.
Sacrilege I know, but can anyone recommend a “supermarket” style cake, or box cake mix that could substitute?
I'm extremely caffeine sensitive too, so have started researching. I haven't been able to enjoy a Thai tea in ages, so would love to experience that taste again! Checking labels/recipes - the Thai powder seems to be: Assam tea + spices (star anise, cardamom, cinnamon and/or clove) + sometimes vanilla and/or pandan + sugar. I can tolerate Harney & Sons decaf black teas lightly brewed (great quality + taste for decaf!) and they have a Decaf Assam. I'm going to try it with that and see.
I made this last night for a dinner party, following the Momofoku Bo Ssam. It was a hit! The toasted coconut and lime zest are so necessary and added some freshness from the lime and a nice slight crunch from the coconut. I made it 2 days in advance and flipped the slides over on the second day. It was hard not to keep sipping the tea steeped in the tres leches. Highly recommend!
Great recipe, my family loved it. Interesting twist on the classic and I actually prefer it! I added the lime zest to the whipped cream topping which added a nice flavor.
I love this recipe! I would definitely recommend adding 0.6 cups of Thai tea powder but it turned out amazing with only 0.5 cups. I would definitely recommend using this recipe 5/5 stars. Ps. Make it late at night so it soaks while you sleep if you are impatient.
I let the cake sit for only 8 hours and the milk mix had only made it half way down. Next time going for the full two days. Also, I am now obsessed with this whipped cream variant.
The sponge for this cake came out absolutely beautifully! Like this is the most beautiful cake I have ever seen! For the tres leches, I ended up using 3.5 cups of milk with the 1.5 cups of evaporated milk because I could only find cans in 12 oz portions, but I didn’t notice any obstacles to the process. It may seem like a lot of liquid at first, but this cake can take it.
I made this exactly as written but won't bother to make it again. I found it to be tasteless - not particularly sweet and the leches didn't add anything to it. The only thing interesting were the golden coconut and the lime zest. I bought Thai tea powder from my local Asian grocery so it was orange (and actually stained a plate!) but, again, meh.
How can you flip it without it spilling all over the place! (How to contain the juices upside down?)
Amazing flavor with two big notes. 1. Use tea leaves, not tea powder. It will get the same effect and is easier to strain. 2. The sponge cake is too dense. I followed the recipe to a Tea. I poked all kinds of holes and let it sit 24 hours before serving and only about half of the milk mixture absorbed.
I really wanted to like this cake but could not give it more than 3 stars. I wanted the Thai tea taste to come through more strongly - maybe it is quite important to soak for two nights. I did just one night, followed the recipe carefully. Honestly the toasted coconut was the most interesting thing about this cake. Pretty color though!
To DD, the whole point of a Tres Leches cake (or any "poke cake" for that matter) is to change the texture of the cake. Why not make it the way it's designed to be made? It's wonderful.
It is against my religion to soak cakes in anything that changes the texture,😱😁 My daughter wanted me to make this. I love Thai ice tea, one I indulge in very rarely. As a compromise, I made the Thai Tres leches about 2 cups and used a slice or two of regular cake to indulge her . Leftover tea diluted with water and ice made me an indulgent Thai ice tea. If anyone else feels the same way about soaking a big batch of lovely cake, here is another option.
Made with liquid Thai tea from Whole Foods and reduced the condensed milk to compensate for the extra liquid. Worked like a charm! Soaked for 2 days, came out delicious
10s 10s 10s all across the board. The cake recipe is quite stiff to accommodate all the milk tea and it holds up so well. I added lime zest to the whipped cream for double citrus vibes. Cannot recommend enough!
Does anyone have issues with the entire cake not turning orange? Any help would be appreciated
I think flipping the cake should help with the color dispersion
Had this for my birthday and it was magnificent. So most, so delicious, not too sweet. Loved the sour cream whipped cream frosting— but definitely had too much of it!
Subbed out the Thai tea powder for 1/3 C matcha powder. It turned out beautifully - light yet decadent, with the tea flavor cutting through the sweetness. For the tres leches, I loosely followed the proportions based on the can sizes- then filled out with whole milk. Great holiday dessert for a crowd!
