Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large mixing bowl, combine the box white cake mix, buttermilk, melted butter, eggs, lemon juice, lemon zest, vanilla extract, and almond extract. Blend on medium speed until smooth, about 2-3 minutes.
Step 3: Grease your 9x13 inch baking pan and pour the cake batter into the pan, spreading it evenly with a spatula.
Step 4: Bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Step 5: Allow the cake to cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely.
Step 6: For the frosting, beat the softened cream cheese until smooth, gradually add powdered sugar, then fold in Cool Whip until fluffy.
Step 7: Spread the cream cheese frosting evenly over the cooled cake with a spatula.
Step 8: Slice into squares and serve chilled for a refreshing treat.
