Preheat oven to 325°F. Prepare a 9x5-inch loaf pan by spraying with a nonstick baking spray which contains flour.

In a medium bowl, whisk together flour, baking powder, baking soda and salt. Set aside.

In a large bowl, beat together butter and sugar until light and fluffy. Add the eggs, one at a time mixing after each addition. Add the vanilla with the last egg.

Mix in the flour mixture and sour cream, just until evenly moistened. Gently fold in the almonds, marshmallows and chocolate chips.

Spread batter into prepared pan and bake in preheated oven for 55-60 minutes or until a tester inserted in the center of the loaf comes out clean.

Move to a wire rack and cool in pan for 30 minutes then turn loaf out onto wire rack and cool completely.
