Start by preheating the oven to 350F (175C).Place the 4 eggs in a large bowl and beat them for 4-5 minutes (you can use a hand mixer).
Start gradually adding the sweetener while mixing. Continue mixing until the mixture is light and fluffy. Then, add the vanilla extract and mix again.
Heat the milk and butter in a saucepan over medium heat for 2 minutes.
Start slowly adding eggs and mixing them until everything is well combined.
Pour into a medium baking dish. Bake for 35-40 minutes. After removing the carnivore cake from the oven, let it rest for at least 30 minutes. Enjoy!
Notes
The Right Baking Dish Makes a DifferenceBake in an 8 × 8-inch or 9 × 9-inch glass or ceramic pan. Larger pans make the cake thin and dry; smaller ones leave the center raw. Butter every corner so the cake slips out cleanly.Watch the Baking Time CloselyStart checking around 35 minutes because ovens vary. The middle should wobble just a little, not look wet, and a toothpick should come out with only a few moist crumbs.Let It Cool CompletelyLeave the cake to rest for at least 20–30 minutes. Cooling lets it finish setting and deepens the flavor; cut too soon and it can break apart.
