Cinnamon-y blueberry muffin perfection. What everyone should wake up to for breakfast!
Muffins:
Crumb Topping:
Preheat Oven to 350* and line muffin tins with liners.
In a mixer or in a mixing bowl with hand held beaters, combine oil, eggs, sugar, and vanilla extract. Combine until creamy and smooth. Add vinegar, sour cream, yogurt, and cinnamon. Incorporate flours and cinnamon at a slower speed, until combined (don’t over mix)
Fold in blueberries, scoop into prepared muffin tins.
If using crumble topping, mix brown sugar, cinnamon, and flour together, and cut in butter until crumbly.
Sprinkle on top of muffins, and bake for 18 minutes.
