<human>:  How do I make a homemade ice cream cake?
<bot>: To make a homemade ice cream cake, you will need ice cream, cake mix, eggs, butter, and some decorations. Begin by preheating your oven to 350°F. Next, mix the cake mix according to the package instructions, adding in the eggs and butter. Grease the bottom of an 8- or 9-inch round cake pan and pour the batter in. Bake for about 30 minutes, or until a toothpick inserted in the center of the cake comes out clean. Remove from the oven and let cool completely. Once the cake has cooled, scoop the ice cream onto the top of the cake and spread evenly. Place the cake in the freezer for at least 2 hours, or until the ice cream is frozen solid. Decorate with your favorite cake decorations and enjoy!
