Raspberry Buttermilk Cake
Adapted from Gourmet, June 2009
You can just ignore the word “raspberry” up there and swap it up with any which berry you please, like blackberries or blueberries or bits of strawberries or all of the above. This is a good, basic go-to buttermilk cake (not unlike a lemon yogurt cake before it) — moist and ever-so-light — a great jumping off point for whatever you can dream up.
By the way, I was having a “moment” when I made this and for once, remembered to weigh my ingredients as I measured them, for all of you people out there that know weighing is way easier than dirtying a zillion cups and spoons. Now let’s just hope my scale is accurate.
Makes one thin 9-inch cake, which might serve eight people, if you can pry it from first two people’s grasp
1 cup (130 grams) all-purpose flour
1/2 teaspoon (2 grams) baking powder
1/2 teaspoon (2 grams) baking soda
1/4 teaspoon salt
1/2 stick (56 grams) unsalted butter, softened
2/3 cup (146 grams) plus 1 1/2 tablespoons (22 grams) sugar, divided
1/2 teaspoon pure vanilla extract
1/2 teaspoon finely grated lemon zest (optional)
1 large (57 grams) egg
1/2 cup well-shaken buttermilk
1 cup fresh raspberries (about 5 oz)
Preheat oven to 400°F with rack in middle. Butter and flour a 9-inch round cake pan.
Whisk together flour, baking powder, baking soda, and salt and set aside. In a larger bowl, beat butter and 2/3 cup (146 grams) sugar with an electric mixer at medium-high speed until pale and fluffy, about two minutes, then beat in vanilla and zest, if using. Add egg and beat well.
At low speed, mix in flour mixture in three batches, alternating with buttermilk, beginning and ending with flour, and mixing until just combined.Spoon batter into cake pan, smoothing top. Scatter (see Note) raspberries evenly over top and sprinkle with remaining 1 1/2 Tbsp sugar.
Bake until cake is golden and a wooden pick inserted into center comes out clean, 25 to 30 minutes (but check in on it sooner, please. Because my oven is new and far from correctly calibrated, I can’t weigh in on the accuracy of this baking time.) Cool in pan 10 minutes, then turn out onto a rack and cool to warm, 10 to 15 minutes more. Invert onto a plate.
Note: Directions like “scatter” always scare me. Where’s the science? Here’s what my neuroses taught us: the ones that were downward were almost all swallowed by the batter. The "o" ones stayed empty, like cups. Both were delicious.
Make your own buttermilk: No need to buy buttermilk especially for this or any recipe. Add one teaspoon of vinegar or lemon juice to one cup of milk and let it sit until it clabbers, about 10 minutes. Voila, buttermilk!
