Banana Tres Leches Cake – classic tres leches cake meets the flavors of the tropics to make one seriously incredible and addictive cake.  This cake is definitely one of my favorites!  I have made it many times and every time I can never stop at just one slice.  It’s not often I use a box cake mix, but with this recipe you would never now it started from a mix.

Tres Leches is such a creamy and moist cake thanks to its “tres leches” translated in English to “three milks.”  Then you throw bananas and coconut into it using this recipe and wow!  Basically this is the cake of Heaven =).

When I bake this cake I just like to pretend it’s my birthday even when it’s not, so I can eat as much of the cake as I want.  This cake was baking in my oven today while I was exercising and boy was it hard to keep going as I could smell the sweet, intoxicating aroma of this cake filling my home.

I kept imaging racing over, as though I had animal instincts and diving into the cake with my hands =).  This cake is just that good!

Wondering what to do with the left over coconut milk you have remaining after making this recipe, try my Pina Colada Floats, a refreshing tropical delight.
