When it comes to cake, you can’t beat an old fashioned recipe that has been passed down through the generations, and this oatmeal cake has been made in my family for years. Subtly spiced and the frosting is to die for!

How to Make This Old Fashioned Oatmeal Cake Recipe

• Place the oats and butter in a large bowl with boiling water and let stand for 20 minutes.
• In a separate bowl mix the flour, baking soda, salt, nutmeg, apple pie spice and cinnamon.
• Once the oatmeal has rested add in the sugars and eggs and mix. Add the flour mixture and combine.
• Pour into a pan and bake.
• Remove the baked cake and pour the frosting over the top.
• FOR THE COCONUT-PECAN FROSTING: In a pan on a medium hit, bring the cream, sugar and salt to a boil. Remove from the heat and stir in the coconut, pecans vanilla and lemon juice.

How long does this cake keep?

Once the cake has completely cooled, transfer it to an airtight container. Keep it in the fridge and it will keep well for two days. The cake can then be eaten cold, or you can gently reheat it in the oven just before serving.

What do oatmeal cakes taste like?

This oatmeal cake recipe is so perfectly moist with a soft crumb texture, it’s just like Grandma used to make! The cake itself is lightly spiced with cinnamon, nutmeg and apple pie spice and it’s perfectly soft. The coconut and pecan frosting adds a delicious sweetness to the cake, as well as a crunchy texture.

What do you serve with this cake?

This oatmeal cake recipe is perfect on its own with a mid afternoon cup of coffee, or served as a dessert. However, I love serving it warm out of the oven with a generous scoop of ice cream. Heaven! It’s perfect with any of these homemade ice cream recipes:

• Red Velvet Ice Cream (Cream Cheese Ice Cream)
• Easy Homemade Pumpkin Ice Cream Recipe

Top tips to make this oatmeal cake recipe

• Be sure to grease your pan before adding the cake mixture for easy removal.
• Don’t over mix when adding the dry ingredients to the wet, as this could cause the cake to become too stiff.
• The frosting should be warm when you pour it over the cake.
• If making ahead of time, allow the cake to cool fully before storing.

For the Coconut-Pecan Frosting

• ▢ 6 tablespoons unsalted butter 85 grams (¾ stick)
• ▢ ¼ cup heavy cream 57 grams
• ▢ ½ cup granulated sugar 100 grams
• ▢ ¼ teaspoon kosher salt

• ▢ 1 teaspoon pure vanilla extract 4 grams
• ▢ 1 tablespoon freshly squeezed lemon juice 14 grams, from ½ lemon

Instructions 

For the Oatmeal Cake

• Preheat oven to 350°F and adjust oven rack to middle position. Spray a 9-inch round cake pan with nonstick baking spray (I used the Nordic Ware Charlotte Cake Pan).
• Place oats and butter in a large bowl and pour boiling water on top. Stir, cover and let the oatmeal mixture stand 20 minutes.
  1 cup quick oats, ½ cup unsalted butter, 1¼ cups water
• In a separate medium bowl, whisk the flour, baking soda, salt, nutmeg, apple pie spice, and cinnamon together.
  1⅓ cup all-purpose flour, 1 teaspoon baking soda, 1 teaspoon kosher salt, ¼ teaspoon freshly grated nutmeg, 1 teaspoon apple pie spice, 1 teaspoon ground cinnamon
• After the oatmeal mixture has rested 20 minutes, add granulated sugar, brown sugar and eggs; stir until incorporated.
  1 cup granulated sugar, 1 cup dark brown sugar, 2 large eggs
• Add flour mixture to the wet ingredients and mix just until the flour in incorporated.
• Pour mixture into the prepared pan and bake at 350°F for 40-50 minutes or until a toothpick inserted in the middle comes out clean.
• While the cake bakes, make the frosting. Beat the butter, cream, sugar, and salt together in a medium saucepan set over medium heat. Bring to a boil and cook 15 seconds.
  6 tablespoons unsalted butter, ¼ cup heavy cream, ½ cup granulated sugar, ¼ teaspoon kosher salt
• Remove from the heat and add coconut, pecans, vanilla, and lemon juice. Mix well.
  ½ cup sweetened shredded coconut, 1 cup chopped pecans, 1 teaspoon pure vanilla extract, 1 tablespoon freshly squeezed lemon juice
• Reheat and stir the frosting to warm right before pouring over the warm cake.
• Remove the cake from the oven and pour the warm frosting over the top. Spread out the frosting to cover the entire cake.
• The cake can be served after 15 minutes (delicious with a scoop of ice cream) or served cold. I love it both ways.
• Allow cake to cool completely before covering for storage.

Becky’s Tips

• You can use half-and-half in place of the heavy cream in the frosting.
• Be sure to grease your pan before adding the cake mixture for easy removal.
• Don’t over mix when adding the dry ingredients to the wet, as this could cause the cake to become too stiff.
• The frosting should be warm when you pour it over the cake.
• If making ahead of time, allow the cake to cool fully before storing.
