Preheat oven to 350F. Butter and line with parchment paper a loaf cake tin.
In a large bowl, combine the sugar and lemon zest. Mix with your hands to release the lemon essence.
Add the eggs, olive oil, and lemon juice. Mix well.
In a separate bowl, mix the flour, baking powder, and salt. Fold in the blueberries.
Add the heavy cream and blueberry-flour mixture into the sugar mixture bowl. Mix just until combined. Transfer the batter into the prepared loaf cake tin.
Bake for 50-60 minutes, until a toothpick inserted into the center comes out clean.
To make the glaze, simply combine the powdered sugar and lemon juice until a thick glaze.
Once the cake has cooled for 15 minutes, add the glaze on top. Let cool another 15-20 minutes for the glaze to set.
Enjoy warm with Vita Ice Acai Blueberry Pomegranate for a refreshing complementary drink! The loaf cake can be stored up to 3-4 days on the counter.
