from the Episode: Old-Fashioned Snack Cakes

To save time, let the eggs, buttermilk, and butter come up to temperature while the browned butter and spice mixture cools. To prevent unsightly air holes in the finished cake, be sure to follow the instructions for removing air bubbles in the batter (see illustrations below). Leftover cake can be stored, covered with plastic wrap, in the refrigerator for up to 2 days. The cake should be brought to room temperature before serving.

2. Heat 4 tablespoons butter in 8-inch skillet over medium heat until melted, 1 to 2 minutes. Continue to cook, swirling pan constantly, until butter is light brown and has faint nutty aroma, 2 to 4 minutes. Add spices and continue to cook, stirring constantly, 15 seconds. Remove from heat and cool to room temperature, about 30 minutes.

Reduce to medium speed and add cooled butter and spice mixture, ginger, and half of egg mixture; mix until incorporated, about 15 seconds. Repeat with remaining egg mixture; scrape down bowl again. Reduce to low speed; add about one-third flour mixture, followed by half of buttermilk, mixing until just incorporated after each addition, about 5 seconds. Repeat using half of remaining flour mixture and all of remaining buttermilk. Scrape bowl and add remaining flour mixture; mix at medium speed until batter is thoroughly combined, about 15 seconds. Remove bowl from mixer and fold batter once or twice with rubber spatula to incorporate any remaining flour.

6. For the frosting: In bowl of standing mixer fitted with paddle attachment, beat butter, sugar, and reserved 1/2 teaspoon spice mixture at medium-high speed until light and fluffy, 1 to 2 minutes. Add cream cheese one piece at a time, beating thoroughly after each addition. Add vanilla and beat until no lumps remain, about 30 seconds.
