As mentioned before, you don’t want to try to substitute marzipan for almond paste with this recipe. Though some may say they are interchangeable, that is not the case. There are a few distinct differences that make almond paste better for this baking application. Marzipan is made with sugar, honey, and almond meal. It’s incredibly sweet. Marzipan does not hold up very well in baking. It’s usually used “as-is” as a filling or for dipping.  Almond paste has a higher amount of almonds than sugar compared to marzipan. It is more coarse than marzipan and holds up much better while baking.
