    Pro Tips and Substitutions

    • Swap Steel Cut for Old Fashioned Oats. If you only have old-fashioned rolled oats, you can pulse them in a food processor to make them more of the texture of quick-cooking. If you prefer a chewier texture, you're welcome to substitute the quick cooking oats with old fashioned oats 1 to 1. We prefer quick-cooking in ours.
    • Use your Favorite Nuts. Substitute walnuts or almonds for pecans if preferred.
    • Preferred Type of Brown Sugar. Regular or dark brown sugar will work for this cake. Dark will yield a more concentrated molasses-like flavor.
    • Use Regular Milk rather than Evaporated. Regular milk can be used in place of evaporated milk, but the topping may be slightly less creamy.
    • Serve with Ice Cream or Whipped Cream. This moist oatmeal cake is delicious with a cup of coffee and with a dollop of fresh whipped cream or a scoop of ice cream on top.
    • Frosting Alternative. While we feel it's the best part of the cake, you're welcome to opt to leave the topping off of the cake. Alternatively, you can allow the cake to cool and spread with this homemade whipped cream cheese frosting!

    Storage and Freezing

    Store leftover oatmeal cake in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Bring to room temperature before serving, or warm individual slices in the microwave for a few seconds.

    This cake can be frozen as well. Wrap it tightly in plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw in the refrigerator overnight before serving.

    Frequently Asked Questions

    Can I use old-fashioned oats instead of quick cooking oats?

    Yes, but the texture may be slightly different. Pulse them in a food processor to make them more like quick-cooking oats.

    Can I make oatmeal cake ahead of time?

    Yes, you can make this cake with oatmeal ahead of time. It tastes like it's been freshly made for 2-3 days! Just cover and store at room temperature. If you're storing it longer, refrigerate.

      Delicious! I made this cake for my parents when I was visiting them and everyone loved it - parents, husband, teenagers. Three-fourths of the cake was gone on Day 1, with the rest quickly disappearing the next day. Will definitely be making again soon. Next time, I will make 1 1/2 times the topping.
