Butterscotch Ice Cream Cake

Butterscotch Ice Cream Cake

Ingredients:
2 cups all-purpose flour
11/2 cup firmly packed brown sugar (I have used a combination of light and dark brown sugar)
100 gm salted butter, softened (If you are using unsalted butter then add 1/2 tsp salt to the flour)
1 tsp vanilla essence
1 cup milk, room temperature (full cream milk will give more richness to the cake)
2 eggs
3 tsp baking powder
1 liter vanilla ice cream
1 liter butterscotch ice cream
4-5 Alpenliebe, coarsely crushed- this is a caramel candy (optional)
Butterscotch sauce (optional)
Method:
Pre-heat the oven to 175 degrees C and place the rack in the center of the oven. 
Sieve together flour and baking powder. Also add salt if you are using unsalted butter. 
In a separate bowl whisk together butter and sugar until it is smooth in texture.
Add the vanilla essence. Beat in the eggs. Add one at a time so it will be easier for you to whisk.
Fold in the flour mix little at a time along with the milk. Mix to form a smooth batter.
Grease a spring-form pan. I have lined it with parchment paper. Now pour the cake batter in this and bake until a tooth pick inserted at the center of the cake comes out clean. Time to bake can vary from oven to oven so keep a close eye on the cake. In my oven it took almost 45-50 mins.
Remove the pan from the oven and let it cool completely. Butterscotch sponge cake is now ready.
Once the cake cools remove it from the pan and cut into half to form two layers.
Keep the butterscotch ice cream at room temperature to soften it. Make sure it doesn't melt you just have to soften it.
Place one layer of the cake back in the pan. Place the ice cream on it. Smoothly spread the ice cream on the cake layer. Now place the second cake layer on this. Once done place the pan in the freezer to set the ice cream layer. It can take 2-4 hrs for the ice cream to set.
Soften the vanilla ice cream to make the top layer of the cake. Take out the cake pan and place the vanilla ice cream on the cake to form the top layer. Smoothly spread it. You can sprinkle the crushed candies to decorate the top layer. You can even use butterscotch sauce for decoration like I did. Click the link for Butterscotch Sauce Recipe . Once done place the cake back in the freezer to set. 
Butterscotch Ice Cream Cake is ready to serve.
Tips!
Dip the knife in hot water, wipe it and then cut the cake with it. 
You can use ice cream flavour of you choice.
