For my DS1's first birthday I made a chocolate cake from my baking with agave cookbook that was made with wholesome flours, zucchini, and agave instead of refined sugar. The icing was buttercream also made with agave. It was wonderful!
For my DS2's first birthday I used the same book and made 3 kinds of cupcakes: fudgy chocolate (made with quinoa flour and iced with buttercream), another type made with zucchini and carrot (iced with cream cheese frosting), and apple cinnamon cupcakes (also with cream cheese frosting). They were sooo good.
