What are Wild Maine Blueberry Muffins?
Maine is the largest producer of wild blueberries – about 99% of all wild blueberries harvested in the US come from Maine! (source). European settlers of Maine who normally used bilberries in baking swapped these berries for the abundant wild blueberries found in this New England State. Blueberry muffins, like many other blueberry baked goods, became a common tradition in Maine. This recipe has the added flavor of lemon, which perfectly compliment the sweet and tart wild blueberries.

Healthy Ingredients in These Wild Maine Blueberry Muffins
Wild Blueberries: you can use either fresh blueberries or frozen. If you use frozen, make sure to thaw and drain them first or the muffins will have excess moisture.
Maple Syrup: maple syrup adds a natural sweetness to the batter without having to use white sugar!
Flour: I like to use ancient grain flour such as einkorn or spelt in this recipe, but you can use regular whole wheat or white flour if you prefer.
Can You Use Regular Blueberries?
If you can’t find wild Maine blueberries or any other wild blueberries, feel free to use regular blueberries in this recipe. The flavor will vary slightly, but will still be delicious!
Topping Options for Wild Blueberry Lemon Muffins

You can either keep these muffins plain or add a variety of toppings! These three topping options are included in more detail in the recipe at the bottom of the post.
Crumble Topping: you can make a healthy crumble topping with sprouted oat flour, butter, and natural sugar! Add the crumble topping on to the batter in the muffin pan orior to baking. The topping will turn golden brown and have a wonderful buttery, caramelized flavor.
Lemon Glaze: prefer a more tart topping? Make a lemon glaze with sugar and lemon. Add this topping after the muffins have baked and cooled off a bit.
Natural Sugar Topping: this is my favorite blueberry muffin topping! Sprinkle natural sugar like sucanat, panela, or coconut sugar on top of the batter in the muffin pan prior to baking. Once baked, the sugar will add a delicious taste and texture to the top of the muffin,
How to Store Wild Maine Blueberry Muffins
Once fully cooled, store in an airtight container on the counter for up to 3 days, the refrigerator for up to 6 days, or the freezer for up to 4 months.
Tips and Tricks
If using frozen blueberries, make sure to thaw and drain them before use or the batter may be too much moisture in the batter.
See the recipe below to adjust for using whole wheat or all purpose flour.
Make sure to cool the butter slightly after melting to avoid killing bacteria in the sourdough starter.
Add the blueberries and lemon after the batter has fermented.
