How to Make Oatmeal Cake
CAKE: Start by pouring boiling water over the oats. This softens them so they blend nicely into the cake. It also helps add moisture to the cake. While that is soaking cream the sugar and butter together in a large bowl. Add the eggs and vanilla and mix until combined.
Stir in the oat mixture. Add the remaining ingredients and mix until combined. Spread in a greased 9×13 baking pan and bake at 350 degrees F for 30-35 minutes or until a toothpick inserted in the center comes out clean.
FROSTING: Melt the butter with the cream in a small saucepan. Add the remaining ingredients and remove from heat. Stir well to combine.
After you remove the cake from the oven spread the frosting in an even layer over the top. Place under the broiler just until golden in color.
