Make the tres leches (milk mixture), pour it inside a squeeze bottle, and refrigerate until ready to soak the cake.
Preheat oven to 350 degrees. Grease your pan using non-stick spray. I used an 8x3 round pan.
In a large mixing bowl or a stand mixer beat butter and sugar on high speed until light and fluffy. For about 5 minutes.
Add eggs one at a time. Beating batter just to combine. Do not overmix.
Add vanilla extract. Then add flour alternating with milk. Starting with flour.
Pour batter into the mold. Bake for about 45-55 minutes. Baking time will depend on the type of mold that you use.
Check the cake with a toothpick/skewer by inserting it in the middle. If it comes out clean with no crumbs on it, the cake is ready to be removed from the oven.
Remove it to a cooling rack and allow it to sit for 10-15 minutes. Then invert it onto a cooling rack and allow it to completely cool before soaking. Divide your cake into two even layers using a serrated knife.
Put the cake layer inside a shallow dish and poke holes using a straw or a kebab stick. Use the squeeze bottle to soak the cake as much as you like.
Fill the cake with mango puree and fresh fruits like berries, mango, and kiwi. Cover with mango whipped cream and enjoy.
