Method
Prep the oven and batter base
- Preheat oven to 375°F and line a muffin tin with paper liners so the muffins release easily after baking.
- Whisk the flour, granulated sugar, baking powder, and salt in a large bowl until the dry ingredients look evenly combined.
- Whisk the eggs, milk, vegetable oil, and vanilla extract in another bowl until smooth and slightly foamy.
- Fold the wet ingredients into the dry until just combined, stopping as soon as you no longer see streaks.
- Fold in the elderberries gently so they stay intact and streaks of purple don’t take over the batter.
- Divide the batter among muffin cups so they’re evenly filled for consistent domes.
Make and add the streusel
- Rub the flour, brown sugar, cinnamon, and cold butter together until crumbly, with pea-size bits of butter visible.
- Sprinkle streusel generously over each muffin and press it lightly so it adheres during baking.
Bake
- Bake at 375°F for 20-22 minutes, until tops are golden and a toothpick inserted in the center comes out clean.
Notes
For best results, toss frozen elderberries in a little flour before folding in so they don’t sink and streak the batter. Cool fully before storing; keep in an airtight container at room temperature for up to 3 days. Freezer: yes—freeze cooled muffins in a sealed bag for up to 2 months and thaw at room temperature. For a lower-sugar option, reduce the granulated sugar to 1/2 cup and consider slightly increasing the streusel cinnamon to keep flavor balanced.
