Instructions
Pecan Pie Filling:
-
Whisk base: In a medium pot, whisk water, egg yolk, and cornstarch until smooth.
-
Add sweetness and nuts: Whisk in brown sugar and chopped pecans.
-
Cook to thicken: Set over medium heat. Whisk constantly until it bubbles and thickens; then boil 1 minute, whisking.
-
Finish and chill: Remove from heat; whisk in butter and vanilla. Transfer to a shallow dish. Cool to room temp, then chill until spreadable.
Note: A quick chill prevents melting the buttercream later.
Brown Sugar Cake:
-
Prep pans: Heat oven to 350°F (175°C). Grease, flour, and line two 8" (20 cm) pans with parchment.
-
Dry mix: In a bowl, whisk flour, baking powder, and salt; set aside.
-
Cream butter & sugars: In a stand mixer with paddle, beat butter, brown sugar, and granulated sugar on medium-high until pale and fluffy, about 3 minutes.
-
Add eggs and vanilla: Reduce speed. Beat in eggs one at a time, fully mixing after each; add vanilla.
-
Alternate additions: With mixer on low, add dry mix in 3 additions, alternating with milk in 2 additions, beginning and ending with dry. Mix just to combine.
-
Bake: Divide batter evenly between pans. Bake 35–40 minutes, until a toothpick comes out mostly clean.
-
Cool: Cool on a rack 10 minutes. Turn out, remove parchment, and cool completely.

Brown Sugar Swiss Meringue Buttercream:
-
Set up double boiler: Place egg whites and dark brown sugar in the stand-mixer bowl; whisk to combine.
-
Heat to dissolve: Set over simmering water. Whisk constantly until hot, glossy, and no longer gritty, about 3 minutes, or until 160°F (71°C).
-
Whip meringue: Move bowl to mixer. Whisk on medium-high until stiff, glossy peaks form and the bowl is cool, 5–10 minutes.
-
Emulsify with butter: Switch to paddle. Add room-temp butter a few cubes at a time; mix until smooth and silky.
-
Flavor: Beat in vanilla. If curdled, keep mixing; if soupy, chill 10 minutes, then beat again.
