Preheat the oven to 350℉ (180℃). Grease a 9x13 inch (23x33 cm) metal cake pan, then lightly dust with flour. Set aside.
In a medium bowl, sift together the flour, baking powder, baking soda and salt. Whisk for about 20 seconds and set asdie.
In a separate large bowl, beat together the eggs and sugar until they're frothy, have lightened in color and increased in volume - about 2 minutes.
Unsure the melted butter is cooled first, then whisk the melted butter, oil, vanilla extract and almond extract egg mixture.
Whisk the milk into the egg mixture. Then using a rubber spatula, gently fold the dry ingredients into the egg and butter mixture. Lastly, with a wire whisk, whisk in the sour cream. If there are a few lumps, that's OK.
Pour the batter into the prepared pan and smooth the top.
Bake in the middle of the preheated oven for 35-40 minutes, or until the top is set and the cake is starting to pull away from the sides of the pan. The top should be firm and slightly springy to the touch and an inserted toothpick should come out clean or with a few moist cake crumbs.
Cool the cake completely in the pan.
