This is my favorite cake ever and not just because I seem incapable of screwing it up. It's pure indulgence, extravagant, and impressive, perfect for a dinner party, and so, so easy to make.
As with all of my favorite recipes, it's a great canvas for versatile flavors from fresh berries and fruit to caramel or chocolate sauces. This would be amazing later in the summer along with ripe peaches. Or add a bit of lemon zest to the whipped cream for a refreshing zing. I could keep riffing on ideas all day, but instead I'll just say: Make this!
Pastel de Tres Leches. Enjoy!
Note: If you do plan to make this cake but don't have a small kitchen scale, go ahead and buy one. You can get them for so little now, and measuring ingredients for baking by weight is really so much more effective. Hint: I use a coffee filter as a container, which is basically weightless, so I don't have to tare out its weight. Easy peasy.
Further: I just spray the cake pan (I use glass without any trouble) with cooking spray, because I'm too impatient to flour pans, and that always works just fine.
And more: There will seem to be too little batter for your 9X13 pan, but it's really alright. Don't panic.
