Place 226 g unsalted butter in a light-colored saucepan over medium-low heat. Allow it to melt completely, then increase heat to medium and cook, swirling or stirring occasionally, until the butter’s solids turn a deep amber brown and emit a nutty aroma. Remove from heat immediately, pour into a heatproof bowl, and discard any burnt sediment. Let the browned butter cool completely to room temperature.

Preheat oven to 175°C. Grease and line the bases of three 20-cm round cake pans with parchment paper. Ensure the buttermilk and eggs are at room temperature and finely chop 160 g pecans to a coarse meal consistency.

In a large bowl or the bowl of a stand mixer, whisk together cake flour, granulated sugar, light brown sugar, baking powder, baking soda, and salt until thoroughly combined.

Add the cooled browned butter to the flour mixture. Mix with a paddle attachment on low speed until the dry ingredients are just moistened and resemble coarse sand.
05 -
In a separate bowl, whisk together buttermilk, eggs, and vanilla extract until fully combined.
06 -
With mixer on low, gradually add half the buttermilk mixture to the flour-butter mixture, mixing until just combined. Add the remaining liquid, mix briefly until smooth. Avoid overmixing. Scrape the bowl, then fold in 160 g very finely chopped pecans.

Divide the batter evenly among prepared pans and smooth the tops. Bake for about 30 minutes, or until a wooden skewer inserted in the center comes out clean and the surface springs back lightly.
08 -
Allow cakes to cool in the pans on wire racks for 15-20 minutes, then use a thin knife to loosen edges. Invert cakes onto racks, remove parchment, and cool completely.

In a stand mixer or large bowl, beat softened unsalted butter, softened cream cheese, light brown sugar, vanilla extract, and salt on medium-high until smooth and creamy, about 3-4 minutes. Scrape down bowl.

Reduce mixer speed to low. Gradually sift in the confectioners’ sugar, mixing just until incorporated after each addition. Increase to medium-high and beat until light and fluffy, 2-3 minutes. Add 1 tablespoon heavy cream, then adjust texture with more cream as needed. Optionally, fold in 35 g very finely chopped pecans.

Level cake layer tops if necessary. Place the first layer on a serving plate, spread with a generous amount of frosting. Repeat with the second layer. Place the third layer upside-down for a flat top, then frost the top and sides evenly.
12 -
Sprinkle additional finely chopped or toasted pecans over the top or sides as garnish. Optionally pipe decorative swirls if some frosting remains. Chill cake for 30-60 minutes to set the frosting before slicing. Serve at cool room temperature.
