Fire up your oven to 350°F (175°C). Spray the base of a 10-inch springform pan lightly with cooking spray.

Hold back 1 cup of the cake mix to create your topping later. In a big bowl, mix the rest of the cake mix with the oil, eggs, and ¾ cup + 1 tablespoon of milk. Use a mixer to combine on high for about 2 minutes—don’t stop until smooth. Pour into the prepared pan.

Mix the butter (melted) and vanilla in a different bowl. Add the reserved cup of cake mix and combine until the texture turns crumbly. Spread these crumbs gently across the uncooked cake in your pan.

Pop the cake into your preheated oven for 30–35 minutes. Use a toothpick to check—it’s done if it comes out clean. Let the cake cool in the pan until it’s at room temperature.

Blend ⅓ cup powdered sugar, lemon zest, lemon juice, and cream cheese together until creamy. Separately, whip the cream with the other ⅓ cup sugar until firm peaks form. Gently fold the cheese-lemon mixture into your whipped cream.

Carefully release the cake from the pan. Slice it horizontally into two even layers with a serrated knife. Spread the filling generously over the bottom layer, then place the top layer gently on top.

Let the assembled cake chill in the fridge for at least 4 hours. Before serving, sprinkle a little powdered sugar over the top for flair.
