Huckleberry Crumb Cake

Originally posted on August 7, 2013

In a previous post I wrote about New York Style Crumb Cake.  Here’s what I said: “There’s crumb cake and there’s coffee cake, and in New York never the twain shall meet. Crumb cakes get their name from their special topping—buttery pea-sized crumbs resting atop a fine-textured butter cake.  You can drink coffee with crumb cake, of course, but don’t call it coffee cake, a non-specific descriptive of just about any kind of cake to enjoy with coffee.”Now that huckleberries are in season where I live, I decided to add some to the cake, and I can tell you, the cake is sensational. Wild Maine blueberries are an excellent substitute for the wild huckleberries that grow in the mountains of western Montana.

The crumb layer for this cake  is thick, and in some recipes it can even equal the thickness of the cake. I like a ratio of 1 part topping to 2 parts cake, because the cake is also a big part of the show. The cake should be moist, tender, and have a fine crumb. The huckleberries add a welcome tang.

Huckleberry Crumb Cake

There’s a lot of butter in this cake, which is why it’s so irresistible. Make the topping first to allow the flour to become completely absorbed by the butter.

Crumb Topping

1 cup firmly packed dark brown sugar
2 ½ cups unbleached all-purpose flour (12 ½ ounces; dip dry measures into flour, fill to overflowing, and sweep off excess level with the cup)
½ teaspoon salt
2 teaspoons ground cinnamon
1 cup (2 sticks) unsalted butter, melted and cooled slightly

Cake

1 ¾ cups unbleached all-purpose flour (9 ¼ ounces; dip dry measures into flour, fill to overflowing, and sweep off excess level with the cup)
2 teaspoons baking powder
½ teaspoon salt
2 cups huckleberries, fresh or frozen
12 tablespoons (1 ½ sticks) unsalted butter, cold
1 cup granulated sugar
2 teaspoons pure vanilla extract
2 large eggs, room temperature
2 large egg yolks, room temperature
Finely grated zest of 1 lemon
1 cup whole milk
Confectioners’ sugar to sprinkle on top of baked cake, optional

Adjust an oven rack to the center position and preheat the oven to 325 degrees.  Butter or coat with cooking spray a 13 x 9 x 2-inch baking pan, dust all over with flour, and knock out excess.
For the Crumb Topping, put the brown sugar into a large bowl and break up any lumps with your fingertips.  Add the flour, salt, and cinnamon, and whisk thoroughly—about 30 seconds—to combine well.  Add the melted butter and stir with a rubber spatula until the mixture gathers into large clumps. Set aside while you make the cake batter.
For the Cake, sift together the flour, baking powder and salt. In a medium bowl, toss 2 tablespoons of the dry ingredients with the huckleberries. Cut the cold butter into tablespoon-size pieces and put them into the bowl of an electric mixer. Let stand 10 minutes to soften slightly. Beat with the flat beater until the butter is smooth and creamy, about 1 minute.  Add ¼ cup of the granulated sugar and the vanilla and beat on medium speed 1 minute.  Scrape the bowl and beater.

While beating on medium speed, gradually add the remaining ¾ cup granulated sugar in a steady sprinkle, taking about 30 seconds to do so. Scrape the bowl and beater. Set the speed to medium high, and beat 4 minutes until smooth and fluffy.

On medium speed, beat in the whole eggs one at a time, then add both yolks and beat 1 minute more.  Scrape the bowl and beater. Beat in the lemon zest.

On low speed, alternately add the dry ingredients in 3 additions and the milk in 2 additions, beginning and ending with the dry ingredients, and mixing after each addition only until smooth. Fold in the floured huckleberries. Scrape the batter into the prepared pan and spread level.

Grab handfuls of the crumb topping, squeeze firmly to compress, and pinch off pea-sized pieces.  You can do this right over the cake in piecemeal fashion or form all the crumbs separately and strew them over the cake all at once.  In either case, the crumbs must cover the batter completely. Very gently, pat the topping in place with the palm of your hand to make an even layer. Do not pack it down.

Bake 40 to 50 minutes, until a toothpick inserted into the center of the cake comes out clean. Make sure the cake is baked all the way through!

Cool completely on a wire rack. Dust with powdered sugar if desired, and cut into squares for serving.

Huckleberry Crumb cake is best when very fresh. Cover leftovers and store at room temperature for a day or two. To refresh, reheat, loosely covered with foil, in a 350 degree oven for about 5 minutes.

Makes 15 to 18 servings.
