Instructions: 1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
2. Prepare the Cake Batter: In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
3. Make the Madagascar Vanilla Custard Filling: In a saucepan, heat the milk and vanilla bean (seeds and pod) over medium heat until just simmering. In a separate bowl, whisk together sugar, egg yolks, and cornstarch until smooth and pale.
4. Assemble the Cake: Once the cake is baked, let it cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
5. Decorate and Chill: Chill the cake in the refrigerator for at least 1 hour before serving to allow the flavors to meld together.
6. Serve: Slice and serve your delicious Vanilla Madagascar Pie Cake and enjoy!
