Instructions

Prep:
Grease and generously flour a 9-inch non-stick cake pan. Toast walnuts in a dry skillet over medium-high heat until lightly golden, then chop finely.

Make Each Cake Layer:

1. Preheat oven to 380°F.
2. In a stand mixer bowl with a whisk attachment, beat 2 eggs and 1 cup sugar on medium-high speed until pale yellow, about 4 minutes. Lower speed to low and gradually add 1 cup flour, mixing until combined.
3. In a large measuring cup, combine 1 cup sour cream with 1 tsp baking soda and 1 tsp vinegar. The mixture will fizz and start to rise—stir immediately into the batter using a spatula.
4. For the first layer, add 1 Tbsp cocoa powder to the batter and mix well. Pour into the prepared pan and bake for 20-22 minutes or until golden and a toothpick comes out clean. Cool to room temperature.
5. Repeat the process for the second layer, adding 2 Tbsp poppy seeds to the batter before baking.
6. For the third layer, stir in ½ cup toasted chopped walnuts before baking.

Frosting:
Using a stand mixer with a whisk attachment, beat the cooked sweetened condensed milk and softened butter on high speed for 3-4 minutes until light and fluffy.

Assembly:
Once cake layers are completely cooled, spread frosting evenly on top of each layer. Stack the layers and frost the top and sides of the cake. Sprinkle the remaining chopped walnuts over the top.
