The Secret Grandma Never Wrote Down
I remember watching my grandmother make her famous Oatmeal Cake Recipe, never measuring too precisely, just going by feel; and yet, it turned out perfect every time. One day, I noticed she’d always let the batter sit quietly for a few minutes before pouring it into the pan. That moment of rest, she said with a wink, was her “secret ingredient.”
Now I know why. Letting the batter rest for 10 minutes allows the oats to soak deeply and the flavors to marry, resulting in a melt-in-your-mouth crumb. But there’s more; combining brown sugar with granulated sugar gives this Oatmeal Cake Recipe a rich depth and warm sweetness that can’t be beat. It’s a humble step, but it transforms good cake into unforgettable comfort.
