1 can (14 oz.) sweetened condensed milk (not evaporated)

Pour into prepared pan.

Bake the cake for 25-30 minutes, until a toothpick inserted in the center comes out clean.  

Meanwhile zest  limes. Do this on a grater with small holes, scraping off only the outside green to gain wonderful flavor. Do not grate into the white pith layer, as this makes the food bitter.Key Lime Poke CakeWhen the cake is cooked through, poke holes, about ½” apart over the entire cakeKey Lime Poke CakeIn a medium bowl, mix together the filling ingredients, just until combined well.

This will thicken up and take more effort to push into the holes if allowed to set up, so it’s best to mix it up as soon as the cake comes out of the oven.Key Lime Poke CakePour half of the filling mixture over the cake Key Lime Poke CakeSpread with a spatula to keep it from running down the side of the cake; directing it into the holes.
