Pre-heat oven to 350 degrees and lightly coat a 5x9" loaf pan in cooking oil.
In the bowl of a stand mixer or in a large bowl with a hand mixer, combine eggs and sugar. Add the milk, vegetable oil, vanilla, cinnamon, nutmeg, lemon juice and lemon zest and mix gently until all ingredients are incorporated.
In separate bowl, whisk together flour (be sure to reserve 2 Tbsp of it), salt, and baking powder. Slowly incorporate the flour mixture into the egg mixture, taking care not to over-mix.
Lightly toss the blueberries in reserved 2 Tbsp flour to prevent them from sinking while the bread bakes. Carefully fold blueberries into the batter.
Pour the batter into the prepared loaf pan and top with coarse sugar.
Bake bread for 50-55 minutes, until it's nicely browned or until a toothpick comes out clean.
