This low-fat tres leches cake recipe is a healthier version of the classic dessert. It uses skim milk instead of whole milk and evaporated milk, and replaces the heavy cream with Greek yogurt. The result is a lighter, less calorie-dense cake that still has all the delicious flavors of the original. The cake is soaked in a mixture of the three milks, which gives it a moist and creamy texture. This recipe is perfect for those who want to indulge in a sweet treat without the guilt.
