Preheat your oven to 325 degrees and grease an 8-inch square cake pan. Optionally, line the pan with parchment paper with overhanging edges for easy removal. In a large bowl, beat together the room-temp butter, oil, sugar, eggs, sour cream, vanilla extract, almond extract, flour, baking powder, and salt. This is a bit of an odd mixing method, but trust the process- you want to just beat everything together at once until just combined. The batter will be thick.
