Preheat oven to 350 degrees.
Grease your pan using non-stick spray.
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.
On low speed add flour alternating with coquito.
Pour batter into the mold.
Bake for about 40 to 45 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 to sit for 10-15 minutes. Then invert it onto a cooling rack and allow to completely cool before using.
Put the cake inside a shallow dish and poke holes using a straw or a kebab stick.
