Sue ~ My coworker is telling me about a Guava Cake with Guava puree on top instead of frosting. They describe it as a sponge type cake pink in color with pureed guava on top. Is this the type of cake this recipe makes? Do you know about the puree frosting? Where do I get pureed guava? I appreciate any help you can offer. This is for 2 coworkers birthdays celebration.

Here is a recipe for a guava cake that has that guava gel as part of the frosting. This one uses a package cake mix and adds some other things into the mix, so it's fairly fail proof.  The guava gel part is comprised of the guava juice, sugar, and cornstarch on the right hand side of the recipe. This should be fairly close to what you're looking for.

Or, there's another recipe for a guava chiffon cake that you can use to get the chiffon texture (try baking it in 8" square baking pans instead of the tube pan). Just frost it with the cream cheese/guava gel frosting from the first recipe and it'll be exactly what you're looking for. Or replace the cream cheese mixture with whipped cream that's been sweetened with powdered sugar and then put the gel on top of the cake.

Both recipes call for guava juice. Since you didn't say where you live (not in Hawai'i, probably), it's hard to tell you where you might be able to find the guava juice. You might be able to find it canned or frozen in a store
that sells Hispanic food in any large city. Or if you live in So. Cali, there are a lot of supermarkets that carry "local" kinds of foods.

Hope this helps. I'm sure your friends will be extremely pleased at your thoughtful gesture!
