Bakery Style Quality

Anytime I see a muffin with a crumb topping, I know it is going to be excellent. And, while you may think by being a bakery style muffin, it is difficult to make, it really is very easy!

To me, a high quality muffin does not always mean a large muffin with a ton of calories. This blueberry muffin is not packed with calories. It is not heavy or dense and it is not packed with so much sugar you need a drink to wash it down with.

This muffin is graced with a small amount of lavender buds in the crumb topping. The lavender lends a delicate flavor that puts these muffins in the out of this world delicious bracket!

💭 Top Tips

For tender muffins, don't overmix the muffin batter. Fold the wet and dry ingredients together until they are just combined.
Always mix the wet and dry ingredients separate first. Then combine the two.
Be gentle when folding in the blueberries so they don't burst.
Crush the lavender buds with a mortar and pestle to release more of the aroma before adding to the crumb topping.
If using frozen blueberries, add them to the batter when frozen. Do not thaw them first.
Check the muffins for doneness with a toothpick or cake tester. The muffin is ready if it comes out clean after being inserted into the center.

📖 Variations

Quick oats can be substituted for whole oats.
Leave out the lavender and add 1 teaspoon of cinnamon to the crumb topping.
Substitute Greek yogurt for the sour cream.
Use ½ teaspoon almond extract in place of the vanilla.
