The batter for this was really thick, almost like cookie dough. The cake comes out nice and moist (not to mention deslicious) with the top almost crunchy cookie-like. The guava is divine. I made this in a loaf pan and it is more like 8 servings, unless you are a piggie like me!
I have made this several times, using an 8x8 square pan. It is more like a big jelly-filled cookie than a cake, but delicious! It is sometimes a little difficult to spread the thick batter in the oiled pan, but a wet spatula helps. Here's a variation you may like to try to make the cake look prettier. If you have some shaped vegetable cutters, cut a slice of extra guava paste and cut out little shapes. Push them into the top layer of the batter.
This was the best ever! I am once again baking it for company today. I am adding a layer of puerto Rican white cheese on top of the guava. Can't wait to see how it turns out. Wonderful recipe. Thanks.
