English Walnut Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the egg yolks.
Pour the batter into a greased cake pan.
Top with English walnuts.
Bake for 25-30 minutes or until a toothpick comes out clean.
