    This old-fashioned oatmeal cake is a buttery cake loaded with oats and cinnamon and topped with a brown sugar and coconut topping, that gives it some extra texture and sweetness. It's warm and comforting like an oatmeal cookie, and pairs so perfectly with a scoop of vanilla ice cream or a dollop of whip cream.

    OLD-FASHIONED OATMEAL CAKE

    My Mom always made this cake in the fall, and I would look forward to it year after year. I tend to love anything with cinnamon and oats because it gives it such a wonderful flavor and texture, but eating it warm with a scoop of ice cream makes even better.

    It's the perfect cake to serve on a cold night when you want to sit and enjoy a little something sweet while watching a movie or having the fire going.

    all ingredients needed to make old-fashioned oatmeal cake

    WHAT IF I DON'T LIKE COCONUT?

    If you don't love coconut you could easily frost this cake with any kind of frosting you prefer. Cream cheese would be fabulous!

    CAN I ADD CHOCOLATE CHIPS?

    YES! ½ cup of chocolate chips would be a great addition to the inside or on top of this cake.

    CAN THIS CAKE BE DOUBLED TO SERVE FOR PEOPLE?

    You can double this recipe and bake in a 9x13 baking pan instead. I would just set the timer for 30 minutes instead and watch it.

    You could also double the recipe and still bake in a 8x8 baking pan for a taller slice of cake.

    Ingredients
     
     

    Oatmeal Cake:

    • ½ cup old-fashioned oats
    • ¾ cup boiling water
    • ¼ cup butter softened
    • ½ cup brown sugar
    • ½ cup granulated sugar
    • 1 large egg room temp
    • 1 teaspoon vanilla
    • ½ teaspoon baking soda
    • ¼ teaspoon salt
    • ½ teaspoon cinnamon
    • ¾ cup all-purpose flour

    Topping:

    • 1 tablespoon butter melted
    • ¼ cup brown sugar
    • 2 tbsp whipping cream
    • ½ cup shredded coconut

    Instructions
     

    • Preheat oven to 350 F. Spray a 8x8 baking pan with cooking spray and line with parchment paper.
    • Place oats in a bowl and pour boiling water over it. Set aside and allow to seap up the water and cool.
    • In a medium size bowl cream together butter and sugars until light and fluffy. Beat in egg. Add vanilla.
    • Add baking soda, salt and cinnamon and mix til combined.
    • Add cooled oats and any leftover liquid. Stir in flour.
    • Pour into greased and or lined pan. Bake for 25 minutes, or until a toothpick comes out clean.
    • Mix topping ingredients together and spread over hot cake. Return to the oven and bake for another 3-5 minutes. Make sure the coconut doesn't burn.

    Notes

    The butter and eggs should be room temperature. I try to let them sit out for about 30 minutes before I begin
    ½ cup of chocolate chips would be a great addition to this cake.
    I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
