Oatmeal cookies and ice cream

As dessert at Amanda and Josiah, Waverly gets oatmeal cookies and ice cream. Waverly has never had ice cream because there isn't any cows on the spaceship she comes from.

Oatmeal cookies:
1/3 cup butter
1 cup oatmeal
1/2 cup and 2 Tbs sugar
1 egg
1 Tbs all-purpose flour
1 tsp vanilla
1 tsp baking powder

Melt the butter and mix in the rest of the ingredients.
Put the dough on baking sheets with a teaspoon. There has to be a lot of space between them because they spreads a lot while in the oven.
Bake the cookies in a preheated oven at 356 Fahrenheit for 10 minuets. Cool the cookies on a wire rack.

Ice cream:
2 Tbs sugar
16 fl oz milk
3 oz sugar
3 egg yokes

Bring cream and vanilla to boiling point. Add sugar and stir until sugar is dissolved. Whisk together the egg yokes and whisk in the milk mixture. Put the cream in a freezer-proof box and put it in the freezer for 3-4 hours or until set.
