Old-Fashioned Rhubarb Cake

September 2036. Tommy's first birthday fell on a clear September day and the land was beginning the persimmon season—the early ones dropping, the main crop a few weeks from peak. I made the birthday food deliberately: a small portion of sweet potato mash that Tommy could manage, a piece of soft cornbread from the heritage grain, a spoon of the wild berry sauce. All food from the land and from the tradition. His first actual birthday meal. He ate the sweet potato with complete focus and looked at the cornbread with deep suspicion before trying it and then eating it in pieces, unhurriedly, with the attention of someone making a careful assessment.

He ate the berry sauce with both hands, which was expected, and was the color of the sauce by the end of it, which was also expected. Kai got a photo of his face. It's the best photo taken on this land since the food forest was planted.

The whole family gathered for the afternoon—the same people who had gathered at every birthday, every Thanksgiving, every important moment on this land. The thirteen-year gathering, you might call it, measured from the first cooking fire I'd built on this ground in the fall of 2022 when the land was new. The people had accumulated around the land the way the soil had accumulated depth—slowly, consistently, through repeated returns.

Tommy sat in the center of it all, berry-stained, studying faces, exactly where he belonged. One year old. A whole life ahead of him on this land if he wants it. I intend to make sure he does.

After a birthday afternoon like that one — berry sauce everywhere, thirteen years of gathered people, a one-year-old studying his cornbread like it owed him an explanation — I wanted a recipe to carry that same spirit forward. This old-fashioned rhubarb cake has always felt like land food to me: tart and sweet at once, nothing hidden, built from something you had to tend and wait for. It belongs at the same table where Tommy sat, stained and satisfied, exactly where he was supposed to be.

Prep Time: 20 minutes | Cook Time: 45 minutes | Total Time: 1 hour 5 minutes | Servings: 12

Ingredients

1/2 cup unsalted butter, softened
1 1/2 cups granulated sugar, divided
1 large egg
1 cup buttermilk
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
2 1/2 cups fresh or frozen rhubarb, chopped into 1/2-inch pieces
1 teaspoon ground cinnamon
1 tablespoon unsalted butter, cut into small pieces (for topping)

Instructions

Preheat and prepare. Preheat your oven to 350°F. Grease a 9x13-inch baking pan and lightly flour it, tapping out any excess.
Cream butter and sugar. In a large bowl, beat the softened butter with 1 cup of the sugar until light and fluffy, about 3 minutes. Add the egg and beat well to combine.
Add wet ingredients. Mix in the buttermilk and vanilla extract until just incorporated. The batter may look slightly curdled — that’s normal.
Combine dry ingredients. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually stir the dry ingredients into the wet mixture until a smooth batter forms. Do not overmix.
Fold in rhubarb. Gently fold the chopped rhubarb into the batter, distributing it evenly throughout.
Pour and top. Spread the batter evenly into the prepared pan. In a small bowl, mix the remaining 1/2 cup sugar with the cinnamon and sprinkle it over the top of the batter. Dot with the small pieces of butter.
Bake. Bake for 40–45 minutes, until a toothpick inserted into the center comes out clean and the top is golden and set. The cinnamon-sugar topping will form a light crust.
Cool and serve. Allow the cake to cool in the pan for at least 15 minutes before slicing. Serve warm or at room temperature. Pairs beautifully with a spoonful of wild berry sauce or a dollop of whipped cream.
