How to Make It
Preheat the oven to 350°.
To prepare cake, coat a 12-cup Bundt pan with cooking spray; dust with breadcrumbs.
Combine granulated sugar and butter in a large bowl; beat with a mixer at medium speed until light and fluffy (about 5 minutes). Add eggs, one at a time, beating well after each addition. Weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 4 ingredients (through salt); stir with a whisk. Add blueberries to flour mixture; toss to coat. Combine 3/4 cup buttermilk, 1/3 cup juice, and extracts. Add flour mixture and buttermilk mixture alternately to sugar mixture, beginning and ending with flour mixture. Pour batter into prepared pan.
Bake at 350° for 45 minutes or until a wooden pick inserted in center comes out clean. Cool pan on a wire rack 10 minutes. Remove cake from pan; cool on rack.
To prepare glaze, place powdered sugar in a small bowl; add 1 tablespoon buttermilk and 1 tablespoon juice, stirring with a whisk until combined. Pour glaze over warm cake; cool completely.
