This baklava layer cake has layers of honey cake that are brushed with a honey milk cake soak, filled with a honey walnut filling and honey buttercream, and drizzled with extra honey.
Preheat oven to 350 degrees. Spray three six-inch cake pans with non stick spray and line the bottoms with parchment paper rounds. Set aside.
Add the butter and sugar to a large bowl and cream together with an electric mixer.
Then add in the egg white and vanilla and mix until smooth, about 1 minute.
Next add in the honey and buttermilk and combine.
In a separate bowl whisk together the cake flour, cinnamon, baking powder, baking soda and salt.
Add the dry ingredients to the wet ingredients and mix until the batter is smooth.
Evenly divide the batter between the prepared cake pans. Bake the cakes for 29-34 minutes or until a toothpick comes out clean from the centers with a few moist crumbs.
Let the cakes cool in their pans for 10 minutes, then transfer them to a cooling rack to finish cooling.
For the Honey Buttercream
Add butter and salt to a large bowl and mix with an electric mixer until the butter is pale and fluffy, 5-10 minutes.
Then mix in the honey.
Add in sifted powdered sugar a little at a time until all is combined. Mix until the frosting is light and fluffy.
For the Walnut Filling
Add the chopped walnuts to a bowl along with 1 cup of the prepared honey buttercream. Mix until combined.
For the Honey Milk Cake Soak
Add the milk to a bowl and microwave it for 10-15 seconds, or until it's slightly warm.
Then add in the honey and stir to combine.
Assembling the Cake
When the cakes are completely cooled, assemble the cake.
First, make each cake layer even by cutting off the domed tops of the cakes.
Then place the first layer down and brush it with the honey milk soak, about ⅓ of the mixture.
Next spoon ⅓ of the walnut filling onto the center of the cake layer.
Add the honey buttercream to a piping bag fitted with a decorative tip. (My favorite tip to use is my Wilton 1M.) Then pipe swirls of frosting around the edges of the cake layer.
Place the next cake layer over the top and repeat the steps twice.
When the cake is assembled, add extra walnuts on top and drizzle on extra honey! Then serve.
Store leftovers in an air tight container for up to four days.
