Preheat the oven to 325 degrees F.
Grease and flour three 8x2 round cake pans. We also like to line ours with circles of parchment paper (optional).
Divide up the half cup of crushed almonds, sprinkling into the bottom of each prepared pan. (To crush/chop, you can use a food processor or bullet blender, or you can place almonds in a ziplock bag and crush with a rolling pin. Crush to the size you like- ours were fairly small but not super fine.)
Add the remaining ingredients to the bowl of your mixer.
Mix the ingredients on low speed with an electric mixer for about 15 seconds to incorporate, then mix on medium speed for two minutes. Scrape down the bottom and sides of the bowl with a rubber spatula as needed.
Pour into prepared pans (over the crushed almonds), and bake at 325 degrees for 22-25 minutes or until an inserted toothpick comes out clean or with just a few crumbs attached. (If you don't have a toothpick, you can insert a thin, sharp knife.)
Cool the baked layers in their pans on a wire rack for ten minutes before turning out.
