Step-by-Step Instructions
- Preheat your oven to 350°F (180°C). Prepare three 8-inch round cake pans by lining the bottoms with parchment paper and greasing the sides.
- In a medium saucepan, bring 2 cups of water to a boil. Stir in 2 cups of quick cook oats, cover, and remove from heat. Let it sit for 20 minutes.
- In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of fine sea salt, 1 teaspoon of ground cinnamon, and ½ teaspoon of nutmeg.
- In a separate bowl, beat together ½ cup of unsalted butter and 1 cup of granulated sugar until light and fluffy, about 3-5 minutes. Add ½ cup of light brown sugar and 3 large eggs, 1 teaspoon of vanilla extract, and 1 cup of full-fat sour cream.
- Gently fold the cooled oat mixture into the wet ingredients, then gradually add the dry ingredients, folding until just combined.
- Divide the batter evenly among the prepared cake pans and bake for 20-22 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes, then invert onto wire racks to cool completely.
- For the frosting, combine 1 cup of unsalted butter, 4 cups of powdered sugar, 2 tablespoons of heavy cream, and 1 teaspoon of vanilla extract. Beat until light and fluffy, about 3-5 minutes.
- To assemble, place one layer on a plate, spread frosting on top, repeat with the second layer, and place the third layer on top. Use remaining frosting to frost the cake.
- Melt 1 cup of white chocolate chips with ½ cup of heavy cream in a small saucepan over low heat. Allow to cool slightly.
- Pour the melted glaze over the top of the assembled cake, letting it drip down the edges.
- Garnish the top with crushed oatmeal cream pie cookies and serve with a scoop of vanilla ice cream or whipped cream.
