Recipe: Honeyberry Buckle (modified from a blueberry buckle recipe, ’cause “honeyberry buckle” is fun to say)
Batter: 3/4 cup sugar, 4 tbsp. butter, 1 large egg, 1/2 cup milk, 2 cup all-purpose flour, 1/2 tsp. salt, 1/4 tsp. each cinnamon and cardamom, 1 tsp. vanilla extract. 2 cups fresh honeyberries OR 2 cups frozen NOT thawed. (Add while still frozen, or the batter will turn an unpleasant pinky-purple color.)
Streusel: 1/2 cup sugar, 1/2 cup all-purpose flour, 1 tsp. cinnamon, 2 tsp. lemon zest, 1/2 tsp. salt, 5 tbsp. softened butter.
For the batter: Preheat the oven to 375 degrees F. Cream the butter and sugar, then add egg and mix at medium speed for 1 minute. Whisk the dry ingredients in a separate bowl. Stir half the dry ingredients into the butter/egg mixture, then stir in the milk and vanilla. Add the rest of the dry ingredients, then gently fold in honeyberries. Spread the batter in a greased 9-inch square or 9-inch round pan.
For the streusel: In a small bowl, whisk the sugar, flour, cinnamon, lemon, and salt. Add the butter and mix with a fork or your fingers to make medium-sized crumbs. Spring the streusel evenly over the batter.
Bake: 45-50 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and cool in its pan on a rack. Serve with coffee in the morning or with whipped cream or ice cream for dessert.
