Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Old-fashioned rolled oats provide the signature chewy texture and hearty base that defines oatmeal desserts.

All-purpose flour gives the cake structure while keeping the crumb soft and tender.

Baking soda helps the cake rise and keeps it light despite the oats.

Ground cinnamon adds warmth and classic oatmeal cookie flavor.

Salt balances the sweetness and enhances the spices.

Unsalted butter adds richness and moisture to the cake layers.

Brown sugar contributes deep sweetness and a slight caramel note.

Granulated sugar balances the brown sugar and helps create a soft crumb.

Eggs provide structure and richness to the cake batter.

Vanilla extract rounds out the flavors and adds warmth.

Milk keeps the batter smooth and ensures a moist cake.

Butter is the base of the cream filling, creating a smooth, rich texture.

Powdered sugar sweetens the filling without making it grainy.

Heavy cream lightens the filling and creates a fluffy, spreadable consistency.

Directions

Preheat the oven and prepare two round cake pans. In a bowl, combine the oats with hot milk and allow them to soften briefly. In another bowl, whisk together flour, baking soda, cinnamon, and salt.

In a large mixing bowl, cream the butter with brown sugar and granulated sugar until light and fluffy. Add the eggs one at a time, then mix in the vanilla extract. Stir in the softened oats, followed by the dry ingredients, mixing just until combined.

Divide the batter evenly between the prepared pans and bake until the cakes are set and a toothpick inserted into the center comes out clean. Allow the layers to cool completely.

For the filling, beat the butter until smooth, then gradually add powdered sugar. Pour in the heavy cream and beat until light and fluffy. Spread the filling generously between the cake layers, then assemble and serve.
