1/2 cup chopped pecans
1/4 cup packed light brown sugar
3 tablespoons butter, softened
1/2 teaspoon ground cinnamon
1 package plain yellow cake mix
1 package cream cheese, at room temperature
1/2 cup vegetable oil
1/2 cup granulated sugar
1/4 cup whole milk
3 large eggs
1-1/2 cups fresh blueberries
Spray a bundt pan with vegetable oil spray. Set pan aside.
To make the streusel place pecans, brown sugar, melted butter and cinnamon in a small mixing bowl and stir until it is well combined. Set the bowl aside.
Place cake mix, cream cheese, oil, sugar, milk and eggs in a large mixing bowl. Blend with an electric mixer on low speed for 1 minute. The batter should look thick and well blended. Pour batter into the prepared pan, smoothing it out with the rubber spatula. Sprinkle the blueberries over the top. Drop streusel mixture by the teaspoonful over blueberries. Place pan on center rack of preheated 350-degree oven.
Bake cake until it is golden brown 45 to 47 minutes.
