First, mix the eggs, sugar, and vegetable oil. Add the flour, baking powder, and vanilla. Pour mixture into a greased cake pan and bake in oven for 30 minutes at 350 degrees F. When cake is finished poke it all over with a knife to create holes to absorb the milk mixture.
Mix the sweetened condensed milk, evaporated milk, half and half cream and regular milk in the blender. Pour milk over the cake little by little allowing it to absorb. Enjoy!!
