• In another bowl, add sugar and butter, cream until fluffy and light in color. Make sure to scrape the side of the bowl. Add the eggs one at a time, continue mixing until well incorporated.
• Add the limoncello, vanilla, lemon zest, and sour cream, mix until well combined.
• Add the dry ingredients gradually. Alternately add dry ingredients and cream. Add them a third at a time. Continue mixing at a low speed, do not overbeat. It's ok if you see bits of flour, just use the spatula to carefully mix the batter until well incorporated.
• Fold in half of the blueberries into the batter. Pour half of the batter into the bundt cake pan, then add the rest of the blueberries. Pour the rest of the batter, tap the pan two times on a flat surface to eliminate air pockets.
• Bake for 35-40 minutes or until the toothpick inserted comes out clean. Cool completely before icing.
