1 cup caster/ultrafine sugar

2 cups flour
1 ½ tsp baking powder
1/2 tsp salt
¼ cup poppy seeds

½ cup orange juice
3 eggs, room temperature
Icing:
8 oz cream cheese, softened
4 Tb unsalted butter, softened
1 tsp vanilla

Preheat oven to 325 degrees. Butter and flour a 8-9 inch round cake pan. Combine buttermilk and poppyseeds in a small bowl or glass measuring cup. Set aside. Sift flour, baking soda, and salt together, set aside.
Cream together the butter, sugar, and zest until pale and fluffy. Add eggs, one at a time, mixing till fluffy and scraping down between each. Add vanilla and mix till combined. Add dry ingredients, buttermilk mixture, orange juice, and mix until just combined. Pour into prepared cake pan and bake for 50-60 mins, or until toothpick inserted in the center comes out clean.
