Blueberry Cinnamon Swirl Bundt Cake Recipes

Steps:

• Heat oven to 350 degrees and set a rack in the center. Spray an 8-by-8-inch square pan with cooking spray and line the pan with a strip of parchment paper that hangs over two sides.
• Make the crumb topping: In a medium bowl, combine the flour, light brown sugar, oats, cinnamon and salt. Add the butter and squish it together with your fingertips until it's evenly moistened, and pebble-size crumbs form.
• Make the cinnamon swirl: In a small bowl, combine the granulated sugar and ground cinnamon; set aside.
• Make the cake: In a large bowl, beat the sugar and butter together with an electric mixer on medium-high speed until light and fluffy, about 4 minutes. Add the eggs one at a time, mixing in one egg completely before adding the next. Add the sour cream, cinnamon, vanilla and salt, and beat to combine.
• Stop the mixer and add the 1 1/2 cups/195 grams flour, the baking powder and baking soda; mix on low speed until just combined. Toss the blueberries with the remaining 1 tablespoon flour, then gently fold them into the batter.
• Assemble the cake: Spoon half the batter into the pan and smooth it to cover the bottom of the pan in an even layer. Sprinkle the cinnamon sugar evenly over the top of the batter. Spoon the remaining cake batter over the top and gently smooth it to cover the cinnamon sugar. Sprinkle the crumb topping over the top.
• Bake the cake for 45 to 55 minutes until puffed and golden, and a tester inserted into the center comes out clean. Serve warm or at room temperature. Store the cake loosely wrapped at room temperature for up to 3 days.

Steps:

• Preheat oven to 400 degrees F (205 degrees C). Grease a 10-inch bundt pan.
• Beat butter and sugar with an electric mixer in a large bowl until light and fluffy. The mixture should be noticeably lighter in color. Add eggs one at a time, allowing each egg to blend into the butter mixture before adding the next. Mix in vanilla.
• Combine flour, baking soda, and baking powder. Pour flour mixture into batter alternately with the sour cream, mixing until just incorporated. Fold in walnuts, mixing just enough to evenly combine. Pour half the batter into the prepared pan.
• Mix the remaining 1/4 cup of white sugar with the cinnamon.
• Sprinkle cinnamon sugar over the batter in the pan. Drop remaining cake batter in heaping spoonfuls over filling, covering it as best you can.
• Bake in preheated oven for 8 minutes. Lower heat to 350 degrees F (175 degrees C) and bake for an additional 40 minutes, or until a tester comes out clean.
