Start by combining the dry ingredients and placing them in a bowl and set aside.
Next separate the egg whites and yolks into separate bowls. Beat the egg yolks until they are pale yellow adding in milk and vanilla extract. Mix with a hand mixer or stand mixer on medium high until the mixture is light in color.
Gently fold in the egg yolk/milk mixture over the dry ingredients just until combined. (don't over mix)
Next, beat the egg whites with a mixer on high until soft peaks form.
Fold the egg whites into the main batter. *Gently* until combined, remember we want to keep the batter nice and fluffy.
Place in a 8X11 baking dish (grease with a bit of butter or nonstick spray) and bake for 25-27 minutes at 350 degrees Fahrenheit or until the top looks golden.
Once the cake is baked and slightly cooled take a fork and gently press holes all over the cake this will help the blueberry tres leches cake to soak in the milk blend.
In a large bowl combine the evaporated milk, condensed milk and heavy cream
Pour the milk mixture over the cake it may seem like a lot of liquid but it will soak in. Let it rest and refrigerate while we work on the delicious whipped topping and blueberry layer.
