Ingredients

Scale

Cookie Cake

  • 1 3/4 cups (228g) all-purpose flour
  • 1 tsp baking soda
  • 3/4 tsp ground cinnamon
  • 1/2 tsp salt
  • 3/4 cup (168g) unsalted butter, room temperature
  • 3/4 cup (168g) packed light brown sugar
  • 1/2 cup (104g) sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 2 cups (175g) uncooked quick cook oats
  • 1 1/2 cups (225g) raisins

Buttercream Frosting

  • 1/2 cup (112g) unsalted butter, room temperature
  • 2 cups (230g) powdered sugar
  • 1/2 tsp maple extract
  • 1/2 tsp ground cinnamon
  • 1–2 tbsp heavy cream

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (180°C). Prepare a 9-inch cake pan by lining the bottom with parchment paper and coating the sides with baking spray to prevent sticking.
  2. Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt. Set aside.
  3. Cream butter and sugars: In a large mixing bowl, beat the room temperature unsalted butter with the brown sugar and sugar on medium speed until the mixture becomes light in color and fluffy, about 2 to 3 minutes. Scrape down the sides occasionally to ensure even mixing.
  4. Add eggs: Add the eggs one at a time to the creamed butter and sugar mixture, beating well after each addition to fully incorporate.
  5. Add vanilla extract: Mix in the vanilla extract until combined.
  6. Combine dry and wet ingredients: Gradually add the dry flour mixture to the wet ingredients, mixing just until combined to avoid over-mixing and tough dough.
  7. Stir in oats and raisins: Using a spatula, fold in the quick cook oats and raisins evenly into the dough. The dough will be thick and sticky.
  8. Press dough into pan: Transfer the cookie dough into the prepared cake pan, pressing it evenly across the bottom. Optionally, press a few extra raisins on top for garnish.
  9. Bake the cookie cake: Bake for 18 to 20 minutes, or until the edges start turning golden brown and the center is set.
  10. Cool the cookie cake: Remove from oven and allow to cool completely in the cake pan. Once cooled, transfer to a serving plate by flipping it out carefully, using two cooling racks to invert and right-side it.
  11. Prepare the buttercream: In a large bowl, beat the room temperature butter until smooth and creamy.
  12. Add powdered sugar: Add half of the powdered sugar to the butter and beat until smooth and incorporated.
  13. Add flavorings and cream: Mix in the maple extract, ground cinnamon, and 1 tablespoon of heavy cream until smooth.
  14. Finish the buttercream: Add the remaining powdered sugar and continue beating until smooth. Adjust consistency by adding more heavy cream if needed.
  15. Decorate the cookie cake: Fill a piping bag fitted with a large decorative tip (such as Ateco 844) with the buttercream. Pipe swirls around the outer edge of the cookie cake for an elegant finish.
  16. Storage: Store the cookie cake in an airtight container. It can be kept at room temperature for up to 24 hours, then refrigerated. Without buttercream, it can stay at room temperature longer. Serve at room temperature for best texture and enjoy within 4-5 days.

Notes

  • Do not overmix the dough after adding the dry ingredients to prevent a tough cookie cake.
  • The cookie cake is best served at room temperature as it firms up when cold.
  • You can press extra raisins on top before baking for a prettier presentation.
  • Buttercream can be piped or spread according to your preference.
  • To invert the cake after cooling, use two cooling racks to safely flip the cake without breaking.
  • This cookie cake keeps well for several days but is freshest within 4-5 days.
