Grease & parchment line 3- 1/8" sheet pans & preheat the oven to 350°F
First prepare the almond paste (or use a good quality store brand) click through to that recipe to see how to make it!
Combine the softened vegan butter & the almond paste in a large mixer bowl & cream until blended together on low to medium speed, stopping to scrape the bottom & sides of the bowl often
Whisk together the cornstarch with the aquafaba then add this slowly into the creamed butter/ almond paste while continuing to mix on medium speed
Scrape the bottom & sides of the bowl again to mix evenly then whip on high speed for about 5 seconds
Add the flour & baking powder, mix to combine evenly
Divide the batter evenly into 3 portions one will be colored red, one green & the other will stay plain white or ivory batter~ Since all food color brands are different start with one tiny drop & go from there
Bake for 18-20 minutes or when the edges just start to get light golden brown~ check at 15 minutes since all ovens bake different~ you do not want to over bake these!
Cool completely then turn out onto a parchment lined sheet pan & freeze to make it easier to assemble
Spread 3 Tbs jam for the filling of each layer
Trim the edges of the frangipane cake & then temper your chocolate
