I improvised this recipe out of necessity to give to my neighbors as a thank you. I started with the basic idea of a frangipane base and substituted sweet potato butter for the almond paste and brown sugar for regular sugar. I upped the flour content and also added honey, cinnamon, nutmeg, and vanilla bean paste. I looked for a specific batter texture more than focusing on my measurements. I know that's a bit of a no no but sometimes you just have to roll with it, which in this instance turned out great. I candied some walnuts before baking the cupcakes and then added them to the top a few minutes before pulling out the cupcakes so they were a nice golden brown color and won't fall off the cupcake when eaten. These were amazing, everyone wants me to make them again... Which means I'll have to make sure to write things down next time.
