Grease and line a springform 9-inch cake pan with parchment paper and preheat the oven to 350°F.
Place the melted butter and sugar in a bowl and beat on medium until light and fluffy, about 4-5 minutes.
8 tablespoons unsalted butter, 1 cup white sugar
Add in one egg at a time and beat until combined completely, about 1 minute per egg.
4 large eggs
Add in the vanilla extract, and almond extract and mix until combined.
2 teaspoons vanilla extract, 1 teaspoon almond extract
In a separate bowl, whisk together (or sift) the almond flour, flour, baking powder, and salt. Add to the butter mixture and fold until combined, being sure to scrape the sides of the bowl to ensure everything is incorporated.
½ cup + 2 tablespoons all purpose flour, 2 cups almond flour, 1 teaspoon baking powder, 1 teaspoon kosher salt
Pour into the cake tin and spread out evenly. Bake for 30-35 minutes, until golden brown, and the edges are beginning to pull away from the sides of the pan. The cake should spring back when touched. Don't turn off the oven!
