- I used bananas that were ripe but not completely dark and squishy.
- You will need about 3 cups of Nilla Wafer from an 11-ounce box to make 1 1/2 cups crumbs. Break up the wafers and pulse in a food processor until they become fine crumbs.
- To toast the nuts: arrange pecans in single layer on baking sheet. Bake in center rack in preheated 350°F oven until fragrant and golden, 7 to 10 minutes, shaking pan halfway through baking to redistribute pecans. Transfer baking sheet to cooling rack and cool pecans completely before chopping.

For the cake: Adjust oven rack to middle position and preheat oven to 350°F. Lightly coat cake pans with baking spray. Line bottoms of cake pans with parchment paper rounds and coat lightly with baking spray once again.
Melt 2 tablespoons butter in medium skillet over medium-high heat. Add mashed bananas and 2 tablespoons brown sugar and cook, stirring, until banana cooks down to a paste and reduces to 1/2 cup, about 10 minutes. Transfer to plate and cool completely, about 10 minutes.
In medium bowl, whisk together cookie crumbs, flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
In separate medium bowl, whisk together buttermilk, vanilla, and cooled mashed bananas.
In large bowl, beat remaining 2 sticks butter and remaining 2 cups brown sugar on medium speed until light and fluffy, about 3 minutes. Add eggs, one at a time, beating well after each addition.
Decrease mixer speed to low and add cookie crumb mixture in three batches, alternating with banana mixture. Scrape sides and bottom of bowl with rubber spatula as needed. Increase speed to medium and beat mixture just until combined, 20 to 30 seconds.
Scrape equal amounts of batter into prepared pans. Bake 30 to 35 minutes, rotating and alternating cakes’ positions halfway through baking, until a cake tester comes out clean when inserted in center of cakes. Transfer to cooling racks and cool in pans 10 minutes. Invert cakes directly onto cooling racks and cool completely, 2 to 3 hours.
For the frosting: Using whisk attachment, whip cream cheese, butter, vanilla, and salt on medium speed until light and fluffy, about 2 minutes. Reduce speed to low, add confectioners’ sugar and light brown sugar, and whip until incorporated, scraping bottom and sides of bowl with rubber spatula as needed, 30 to 60 seconds. Increase speed to medium-high and continue to whip until frosting is light and fluffy, 2 to 3 minutes. Stir in pecans.
To assemble: Place one cake round on serving dish or cake stand and spread with a heaping cup of frosting. Top with second cake round and frost sides and top of cake. Serve.
