If you are in the mood for a delicious cake that tastes like it’s straight out Grandma’s kitchen, then my oatmeal cake just might fit the bill. This old fashioned cake is tender but not too sweet, while the topping is a sweet glaze that highlights shredded coconut and pecans.
This humble cake is anything but plain. The topping is broiled until the glaze is almost like a brulee. It just might become a family favorite. You can serve this lovely dessert after dinner or any time of the day for a sweet treat.

MOIST OATMEAL CAKE INGREDIENTS
- Quick-cooking oatmeal: Make sure the oats are quick-cooking and not Old Fashioned oats. The quick-cooking oats are thinner and will cook faster.
- Baking soda: This is the leavening for the cake.
- Hot water: The oats will soften in the hot water. Use filtered or tap.
- Butter or margarine: I prefer unsalted butter.
- Brown sugar: This ingredient adds a nice deep sweet flavor to the cake.
- Granulated sugar: For straightforward sweetness.
- Eggs: I use large.
- Vanilla extract: 100% pure extract
- All-purpose flour: A pantry staple.
- Cinnamon: Ground cinnamon for those warm notes in the cake goes well with oats.
- Shredded coconut: For the glaze, so chewy and sweet!
- Pecans: A Southern classic. You may substitute for walnuts or chopped almonds too.
- Milk: Whole milk for a rich glaze.
TIPS
- Stand-Up Mixer: If creaming sugar and butter, I typically use the stand mixer. My arm gets tired with a handheld, and the stand mixer does the work for you.
- Variations: Add raisins (1/2 cup) if desired. Omit the shredded coconut and/or nuts and just top with the glaze. But don’t skip the last step. Getting the glaze hot and bubbly is a big part of this cake’s charm!
