Step 1

Preheat oven to 300°F (148°C).

Step 2

Put all dry ingredients in a large bowl and whisk together.

Step 3

Add eggs, buttermilk and vegetable oil to the dry ingredients and mix until smooth.

Step 4

Add vanilla to boiling water and add to mixture.

Step 5

Mix at medium speed until smooth.

Step 6

Pour into one 8-inch pan and bake 40-42 minutes.

Step 7

Remove from oven and let cool for 5-10 minutes in pans, then remove to cooling rack to finish cooling.

Step 8

Once cooled, cut off cake dome with a long serrated knife.

Step 9

Once the cake has cooled, make the strawberry ice cream. Combine the cream cheese and sugar in the bowl of a mixer until smooth. Add the milk and strawberry extract and mix until completely combined.

Step 10

Fold in the cool whip and food color, then set aside.

Step 11

To make the vanilla ice cream, combine the cream cheese and sugar in the bowl of a mixer until smooth. Add the milk, vanilla bean paste and vanilla extract and mix until completely combined.

Step 12

Fold in the cool whip.

Step 13

Line the sides of an 8-inch springform pan with parchment paper. The parchment paper should stick up above the top edge of the pan, since the cake will probably be a little taller than your pan. If you want, put a cardboard cake circle in the bottom of the pan. You should be using the same 8-inch pan you used for the cake. Not all 8-inch pans are exactly the same size. Your cake needs to fit in this pan.

Step 14

Put the chocolate cake in the bottom of your pan.

Step 15

Top cake with the strawberry ice cream and spread into an even layer.

Step 16

Carefully add vanilla ice cream and spread into an even layer.

Step 17

Allow ice cream cake to freeze completely, 6-8 hours.

Step 18

When frozen, remove cake from springform pan and remove parchment paper from sides.

Step 19

To make icing, put mixing bowl and whisk attachment in freezer for about 10 minutes.

Step 20

Remove bowl and whisk from freezer and whip cream on high until it begins to thicken.

Step 21

Add vanilla extract and powdered sugar and whip on high until thick and creamy.

Step 22

Ice cake and freeze until serving.
