For the Orange Almond Cake:

1. Prep the pan: Preheat your oven to 350°F (175°C) and grease and flour a 9-inch cake pan.
2. Mix wet ingredients: In a bowl, whisk together the eggs, sour cream, almond extract, vanilla extract, orange extract, and orange zest.
3. Mix dry ingredients: In a stand mixer, combine the flour, ground almonds, sugar, baking powder, baking soda, and salt. Mix at low speed.
4. Combine wet and dry: Add the butter and the remaining sour cream to the dry ingredients and mix on low speed until evenly incorporated. Increase to medium speed and beat for 1-2 minutes. Add the wet mixture in parts, scraping the sides of the bowl to ensure even mixing.
5. Bake: Pour the batter into the prepared pan and bake for 35-45 minutes or until a toothpick comes out clean. Cool on a wire rack before removing from the pan.

4. Cream butter and sugar: Beat the butter and sugar in a stand mixer until light and fluffy. Add the egg and vanilla extract, mixing until incorporated.

For the Orange Cream Cheese Frosting:

1. Beat cream cheese and butter: Beat the room-temperature cream cheese and butter until smooth and creamy.
2. Add sugar and zest: Gradually mix in the confectioner’s sugar and orange zest. Continue to beat until smooth.

For the Rich Chocolate Frosting:

1. Heat cream: In a saucepan, heat the cream over medium heat until it starts to bubble at the edges.
2. Melt chocolate: Chop the semisweet chocolate and add it to the cream. Let it sit for a minute, then whisk until smooth.
3. Add butter: Stir in the butter until the frosting is glossy and smooth. Let it cool slightly before using.

Assembly:

1. Prepare cake layers: Once all cakes are completely cooled, trim the tops of the cakes to make them level if needed.
2. Layer the cakes: Place the orange almond cake layer on a cake stand or large plate. Spread a thin layer of the orange cream cheese frosting over the top.
3. Add chocolate layer: Place the chocolate cake layer on top of the frosting.
4. Frost with chocolate frosting: Pour the rich chocolate frosting over the top of the cake, letting it flow down the sides. Spread it evenly across the cake.
5. Decorate: If desired, press sliced almonds into the sides of the frosting or pipe decorative swirls on top.

Serving:

Let the cake chill in the fridge for at least an hour to set the frosting. Before serving, remove it from the fridge 1-2 hours to bring it to room temperature for the best flavor.
