Ingredients

Lemon Cake

Lemon Crunch

  • 10 lemon Oreo cookies
  • 3.4 ounce instant lemon pudding (use ½ of the box)
  • 2 tablespoons butter, melted
  • ½ teaspoon lemon juice

Lemon Cream Cheese Frosting

Instructions

  • Preheat the oven to 350 degrees. Grease and lightly flour (2) 8-inch round cake pans.

Lemon Cake

  • In a medium bowl, whisk flour, baking powder, baking soda, and salt together. Set aside.
  • In a large mixing bowl, beat butter until creamy. Add sugar, lemon juice, and lemon zest, and beat until combined.
  • Add eggs, one at a time, and beat until combined.
  • Next, add flour mixture, alternating with buttermilk, and mix on low speed after each addition until combined.
  • Pour cake batter evenly into prepared cake pans.
  • Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
  • Cool on a wire rack and remove from the pans after 10 minutes. Cool cakes completely before frosting.

Lemon Crunch

  • Line a baking sheet with parchment paper. Set aside.
  • In a food processor, pulse lemon cookies until coarsely crushed.
  • In a medium bowl, add the crushed cookies and mix with the lemon pudding.
  • Add melted butter and stir until combined.
  • Spread lemon crunch mixture onto the prepared baking sheet and bake for 10 minutes.
  • Remove from the oven and let cool.
  • Once the cake is frosted, add the lemon crunch to the sides of the cake and on top, if desired.

Lemon Cream Cheese Frosting

  • In a medium bowl, beat cream cheese, butter, and lemon juice until light and fluffy.
  • Gradually add powdered sugar, one cup at a time, and beat until desired consistency is obtained.
  • Stir in the lemon zest.
  • Add a layer of frosting between the layers of cake, and frost the sides and top.
  • Optional: slice each cake in half lengthwise to make a 4 layer cake, if desired.

Notes

Tips
  • Fresh Lemon Juice & Zest: Use fresh lemon juice and zest for the best flavor.
  • Cool the Cake Completely: Make sure cake layers are completely cool before frosting.
  • Chill Before Adding the Lemon Crunch: Chill the cake slightly before adding the crunch to make it easier to handle.
  • Don't Overmix: Don’t overmix the batter to keep the cake light and fluffy.
  • Line the Pans with Parchment Paper: Line the bottoms of the cake pans with parchment paper, leaving two strips hanging over the sides. The strips make handles for easy removal.
