Berry Buttermilk Cake

This recipe is from the July issue of Bon Appétit magazine, originally for Blackberry Buttermilk Cake. I used blueberries and raspberries, as the blackberries from the garden have already come and gone.

If you read the comments on the recipe link, you'll see that there was a wide range of results, from overcooked to raw. I used a 10", glass-bottomed springform pan, set slightly higher than the middle of the oven. At 1 hr, the top of the cake did look quite brown, probably due to my poor positioning of the oven rack, so I covered it with a loose piece of foil, and it turned out just right when checked at 1:20.

As I sometimes (but not always) do when trying a recipe for the first time, I followed the recipe almost to the letter, including the double-sifting of the cake flour. (I did leave out the orange zest.) All ingredients were at room temperature. The sugar was a slightly coarser grain than my usual baking sugar, but as I said, it seemed to turn out just fine. The cake was moist and had a nice, creamy flavor, and the raspberries added just the right tang to the sweet blueberries. (About 3/4 blueberries to 1/4 raspberries).

When I do this again, I don't see any reason to use a springform, rather than the upside-down cake method (Plum or Pear) in a regular pan, as long as your pan is both wide and high enough to hold this amount of batter. A thicker pan will transfer heat more evenly than a thinner pan, so use a good quality cake pan.

I found the sequence below of, "Remove pan sides. Invert cake onto rack and remove pan bottom; peel off parchment." to be unnecessarily complex, not to mention awkward with a warm cake. (We had a bit of a fail on this part, which didn't affect the deliciousness.) Much easier to invert a single cake pan onto a plate, allow to cool further and remove, or, if you've used a parchment circle, cool, invert, de-pan, remove parchment. If you do use a springform, I'd recommend loosening the edge with a knife, then inverting onto a plate, then removing the sides, then the bottom, then the parchment, rather than trying to get a rack involved.

All that said, this is a very tasty cake. I may just adapt my normal USDC recipe and use sifted cake flour and buttermilk to get the flavor without the fuss.

Berry Buttermilk Cake

Ingredients

3/4 cup (1 1/2 sticks) unsalted butter, room temperature, plus more for pan and parchment
2 1/3 cups cake flour (sifted, then measured) plus more for pan
2 1/2 cups (10 ounces) fresh blackberries
1/4 cup plus 1 1/3 cups sugar
1 1/2 teaspoons baking powder
3/4 teaspoon salt
1/2 teaspoon baking soda
3 large eggs, room temperature
2 teaspoons vanilla extract
1 1/2 teaspoons finely grated orange zest
1 cup well-shaken buttermilk
Powdered sugar (for dusting)
special equipment:

Use a 9"-10"-diameter springform pan
Preparation

Position a rack in middle of oven and preheat to 350°. Butter pan; line bottom with a round of parchment paper. Butter parchment. Dust with flour; tap out excess. Arrange berries in a single layer in bottom of pan; sprinkle evenly with 1/4 cup sugar.
Sift 2 1/3 cups flour, baking powder, salt, and baking soda into a medium bowl; set aside. Using an electric mixer, beat 3/4 cup butter and remaining 1 1/3 cups sugar in a large bowl at medium-high speed, occasionally scraping down sides of bowl, until pale and fluffy, about 2 minutes. Add eggs, one at a time, beating well after each addition. Beat in vanilla and zest. Reduce speed to low; beat in flour mixture in 3 additions, alternating with buttermilk in 2 additions, beginning and ending with flour mixture and beating just until incorporated. Pour batter over berries in pan; smooth top.
Bake until cake is golden brown and cake bounces back when pressed gently with fingertip, about 1 hour 25 minutes for a 9" pan and about 1 hour for a 10" pan. Let cool in pan set on a wire rack for 15 minutes, then run a thin, sharp knife around the edge of the pan to loosen. Remove pan sides. Invert cake onto rack and remove pan bottom; peel off parchment. Dust top generously with powdered sugar and let cool completely.
