On Friday, I was reading Dorie Greenspan's excellent blog where she wrote about a blueberry breakfast cake. That got me thinking about her recipe for Blueberry Crumb Cake from her book, Baking: From My Home to Yours. Soft and flaky, with fresh blueberries bursting in each bite. I can't stop thinking about it. I made it yesterday morning with the idea of having it for dessert last night but by mid afternoon I couldn't resist any longer! My family came home to a beautiful crumb cake sitting on the counter, missing a big piece! I, of course claimed that I needed to sample it in the name of quality control!
Blueberry Crumb Cake
Adapted from Baking: From My Home to Yours by Dorie Greenspan
INGREDIENTS:
For the crumbs:
5 tbsp unsalted butter, at room temperature
1/4 cup sugar
1/3 cup (packed) light brown sugar
1/3 cup all purpose flour
1/4 tsp salt
1/2 cup chopped walnuts (I omitted this)
For the cake:
1 pint (2 cups) blueberries (preferably fresh, or frozen, not thawed)
2 cups plus 2 tsp all purpose flour
2 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1/4 tsp ground cinnamon
1/8 tsp freshly grated nutmeg
2/3 cup sugar
grated zest of 1/2 lemon or 1/4 orange
3/4 stick (6 tbsp) unsalted butter, at room temperature
2 large eggs, at room temperature
1 tsp pure vanilla extract
1/2 cup buttermilk
DIRECTIONS:
Preheat
oven to 350 and place the rack at the middle position in the oven.
Butter an 8-inch square pan and put it on a baking sheet.
To make
the crumbs: Put all the ingredients except the nuts in a food processor
and pulse just until the mixture forms clumps and curds and holds
together when pressed. Scrape the topping into a bowl, stir in the nuts
and press a piece of plastic wrap against the surface. Refrigerate
until needed. (Covered well the crumb mix can be refrigerated for up to
3 days.)
To make the cake: Using your fingertips, toss the
blueberries and 2 tsp of the flour together in a small bowl just to
coat the berries; set aside. Whisk together the remaining 2 cups flour,
baking powder, baking soda, salt, cinnamon and nutmeg.
Working
in the bowl of a stand mixer or in another large bowl, rub the sugar
and zest together with your fingertips until the sugar is moist and
aromatic. Add the butter and, with the paddle or whisk attachment, or
with a hand mixer, beat the sugar with the butter at medium speed until
light, about 3 minutes. Add the eggs one by one, beating for about 1
minute after each addition, then beat in the vanilla extract. Don’t be
concerned if the batter looks curdled — it will soon smooth out. Reduce
the mixer speed to low and add the flour mixture and the buttermilk
alternately, the flour in 3 parts and the buttermilk in 2 (begin and
end with the dry ingredients.) You will have a thick, creamy batter.
With a rubber spatula, gently stir in the berries.
Scrape the
batter into the buttered pan and smooth the top gently with the
spatula. Pull the crumb mix from the fridge and, with your fingertips,
break it into pieces. There’s no need to try to get even pieces — these
are crumbs, they’re supposed to be lumpy and bumpy and every shape and
size. Scatter the crumbs over the batter, pressing them down ever so
slightly.
Bake for 55 to 65 minutes, or until the crumbs are
golden and a thin knife inserted into the center of the cake comes out
clean. Transfer the cake to a rack and cool just until it is warm or
until it reaches room temperature.
