Before we dive in, remember to preheat your oven to 325 degrees Fahrenheit and generously butter a 10-cup cake pan.
Step 1: Cream butter and sugar
In a large mixing bowl, beat together 2 cups unsalted butter and 4 cups granulated sugar until they are light and fluffy. This should take around 5-7 minutes.
Step 2: Add eggs
Next, add 8 large eggs into the mixture one at a time, beating well after each addition.
Step 3: Add flour mixture
In another bowl, sift together 3 cups all-purpose flour and 1 teaspoon baking powder. Gradually add this to the butter mixture, alternating with 1 cup sweet milk, beginning and ending with the dry ingredients. Mix until just combined.
