This is my Mom's recipe fleshed out a little - her directions are pretty sparse.
1 Cup sugar
2 eggs
1 tsp. baking soda
2 Tbsp. buttermilk or sour milk (mix a drop of lemon juice with milk)
2 Cups flour
1 tsp. vanilla
2 Cups apples, peeled and chopped
1/2 cup walnuts, chopped
1 tsp. cinnamon
1/4 tsp. nutmeg
1/8 tsp. ground cloves
Topping
2 Tbsp. butter, melted
2 Tbsp. sugar
2 Tbsp. flour
1 tsp. cinnamon
Preheat oven to 350 degrees.
Blend butter and sugar together. Add eggs and blend again. Dissolve baking soda in the buttermilk and add to butter and sugar mixture. Add the remaining ingredients and mix until combined. Spoon into a loaf pan. This will make one regular size loaf or two flat loaves. The batter does not rise much. We usually opt for two loaves as the bread is very moist.
Mix topping ingredients together and sprinkle on top of loaf. Bake 30 minutes to one hour until a toothpick comes out clean.
