Preparation
- Preheat oven to 425°F.
- Make the streusel by mixing brown sugar, 1/3 cup flour, ground cinnamon, and melted butter until pea-sized chunks form. Set aside.
- In a large bowl, whisk together cornmeal, 2 cups flour, baking powder, and salt.
- In a medium bowl, whisk sugar and eggs until smooth. Whisk in melted butter and canola oil until mixed. Add buttermilk and vanilla, whisking until combined.
- Fold the egg mixture, half of the blueberries, and lemon zest into the flour mixture until just moistened. Do not overmix.
Baking
- Divide batter into muffin tins.
- Top each muffin with the remaining blueberries and sprinkle with streusel.
- Bake for 13 to 15 minutes.
- Optionally, make a lemon glaze by mixing lemon juice and powdered sugar for drizzling on cooled muffins.
