Ingredient Notes

Butter – used for both the streusel and muffins for that perfect buttery texture
Light brown sugar – Used for both the streusel and muffins, brown sugar adds so much flavour and caramelization
Granulated Sugar – will give sweetness and a denser texture
Eggs – will create a muffin that is moist, spongy and tall
Sour Cream – gives so much moisture and is key to create that classic muffin texture
Vanilla Paste – adds so much flavour and richness
Baking Powder + Baking Soda – creates height for the best bakery style muffin tops
Fresh Blueberries – are the best to create moist muffins and get a lot of blueberry flavour
Plain Flour – is all we need to create these simple and wonderfully textured muffins
Salt – will balance out the muffins and bring out more blueberry flavour
Milk – adds some tenderness and more moisture

Fresh blueberries vs. Frozen blueberries
Personally I like using fresh as it stays intact and doesn’t bleed too much into the batter but, honestly frozen berries also work and are great when you are in a pinch! The frozen berries add more colour to the batter but can add a lot of water content so, baking the muffins for a little longer is recommended.
