Grease two 9-inch pans. Line the bottom with parchment paper. Preheat an oven to 350 degrees F.
In a large mixing bowl, use a hand mixer to cream the butter and sugar together. Beat in almond extract. Beat in sour cream until just combined.
Use a fork to combine the eggs and milk together in a bowl or 2 cup liquid measuring cup. Set aside.
In another mixing bowl stir together cake flour, baking powder, and salt.
Add 1/3 of the dry ingredients to the butter mixture and mix in until just combined. Add in half of the milk mixture and combine. Add in another 1/3 of the dry ingredients until combined followed by the remainder of the milk mixture. Add in the remainder of the dry ingredients and mix with the hand mixer until just combined, using a rubber spatula to scrape the sides and bottom to make sure everything is mixed in.
Divide the batter evenly between the prepared pans. Bake at 350 for 25 to 30 minutes. Let sit in pans for 5 minutes and then transfer to a wire rack to cool completely before layering and frosting.
Buttercream Frosting
Use a hand mixer to whip softened butter and almond extract together. Slowly add in powdered sugar, about 1 cup at a time. Thin out with milk if it gets too thick.
