Step-by-Step Instructions
The first thing I always do is preheat my oven to 350°F (175°C) and lightly grease my baking pan. I’ve learned from experience that lining the pan with parchment paper makes removing the cake much easier later. In a large bowl, I mix the yellow cake mix, melted butter, and one egg until it forms a thick dough. The mixture will feel more like cookie dough than cake batter, which surprised me the first time I made it. (See the next page below to continue steps…)
