For the Cake:
- Flour-based cooking spray
- Vegan egg replacer equivalent to 1 egg (I used Bob's Red Mill)
- 3/4 cup granulated sugar
- 1/2 cup vegan sour cream
- 1/4 cup vegan butter softened
- 1 cup overripe bananas mashed
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/4 cup walnuts chopped
For the Frosting:
- 3 cups confectioners' sugar
- 1/4 cup vegan butter softened
- 1 tablespoon oat milk or other mild-flavored plant milk, such as unsweetened almond
- 3/4 teaspoon vanilla extract
- 1/4 cup walnuts chopped
For the Cake:
Preheat the oven to 350°F. Spray an 8x8-inch with flour-based cooking spray.
Prepare the egg replacer according to package directions; set aside.
In a medium bowl, use a hand mixer to cream the sugar, sour cream, and butter. Add the mashed banana and vanilla extract; mix just until incorporated.
Add flour, baking soda, and salt, then continue mixing until incorporated. Stir in 1/2 cup walnuts.
Spread the batter in the prepared pan and bake for 25 minutes, until a toothpick inserted in the center comes out clean. Set on a wire rack to cool completely.
For the Frosting:
In a small saucepan over medium heat, melt the butter and let it cook, stirring frequently, for 3-5 minutes, until bubbly and lightly golden brown in color. Remove from heat and cool completely.
In a medium bowl, use a hand mixer to combine the cooled butter with the confectioners' sugar, milk, and vanilla extract until the consistency is smooth.
Spread frosting over cooled banana bread cake, sprinkle with the remaining 1/4 cup walnuts, and serve.
