Lobelia's Spiced Yule Cake
Despite the fact that Lobelia never got along with Bilbo, she took a strange liking to Thorin when he moved to the Shire. She would often (and much to Bilbo's chagrin) bring him gifts of food, including her famous Spice Cake. Thorin immediately fell in love with the cake, which prompted Bilbo to actually go to Lobelia and ask her for the recipe. She absolutely refused to share it with him, and so he stormed off in defeat.
Still, as a Yule gift that year, Lobelia gave Thorin himself the recipe, making him swear on his honor not to share it with anyone, Bilbo included. To his credit, Thorin respected her wishes, ushering Bilbo out of the kitchen whenever he prepared the cake. And though the first few times he had done so Bilbo huffed and fussed, eventually he accepted that to either make Thorin share the recipe with him or to sneak a peek while it was being prepared would not only be dishonorable, but also would damage Thorin's trust in him.
However, over the next year (and with Thorin's help), Lobelia and Bilbo's relationship improved somewhat, and when the next Yuletide came around, she at last gave Thorin her blessing to share the recipe with Bilbo.
Please feel free to take the recipe and distribute it as you like; no credit is necessary.
Lobelia's Spiced Yule Cake
1/2 cup buttermilk (see note)
Preheat oven to 350 degrees. Grease and flour an 8- or 9-inch cake pan (or line with parchment paper).
Beat together the butter and sugar until fluffy. Beat in the eggs, one at a time, until fully combined. Sift in the four, baking soda, and spices; mix until just combined. Add the buttermilk and mix on low until no flour streaks remain.
Turn batter into prepared pan. Bake for 25 - 30 minutes, or until surface is golden and a toothpick or butter knife comes out clean when inserted into the center.
Cool completely, then dust with powdered sugar.
Note: If you don't have buttermilk on-hand, you can simply put 1 1/2 teaspoons of vinegar or lemon juice into a measuring cup and fill up the rest of the way to the 1/2 cup mark with milk or half-and-half, then let it sit for about five minutes.
Note #2: You may want to adjust the spices for your liking, as one teaspoon of each may not suit everyone; and also, you might like to try other spices (such as cloves) as well!
