Preheat oven to 350 degrees F

Generously grease an 8-inch square cake pan

In a large bowl, cream the butter and sugar together until light and fluffy (use hand mixer)

Add the egg, apples, nuts and vanilla and stir well

Sift in the dry ingredients and mix well

Pour the batter into the prepared pan & bake about 45 minutes, until the cake is lightly browned and a toothpick inserted into the center comes out clean.

Remove from over and let the cake set in the pan for 5 mins, then remove from pan (I didn't remove it).

Serve warm or at room temperature with whipped cream or vanilla ice cream.
