How To Make Martha Stewart Banana Nut Cake
- Prep oven and pan: Preheat your oven to 350°F. Butter a 9-by-5-by-3-inch loaf pan and set aside.
- Cream butter and sugar: In a stand mixer fitted with the paddle attachment, cream together butter and sugar until light and fluffy.
- Add eggs: Beat in the eggs one at a time until fully incorporated.
- Combine dry ingredients: In a medium bowl, whisk together flour, baking soda, and salt.
- Mix dry with wet: Gradually add the dry ingredients to the butter mixture, mixing until just combined.
- Add bananas and sour cream: Stir in the mashed bananas, sour cream, and vanilla until the batter is well mixed.
- Fold in nuts: Gently stir in the chopped walnuts or pecans.
- Bake the cake: Pour the batter into the prepared pan and bake for about 1 hour and 10 minutes, or until a tester inserted into the center comes out clean.
- Cool: Let the cake rest in the pan for 10 minutes, then transfer to a wire rack to cool completely.
