Directions 4 steps | 30 Minutes
Preheat oven to 360°F and prep and gather all ingredients.
In the large bowl, mix sugar and eggs. Beat the eggs and sugar for 5 minutes or until the mixture is doubled in size. Slowly add flour, and mix well until combined. Add milk, orange zest, vanilla extract and mix well. Slowly add oil and baking soda. Mix very slowly after adding oil as the oil is heavy. Finally, fold in the blueberries. Add the batter into the muffin tray.
Make the topping by mixing together the flour, sugar and butter until the butter is pea-sized and the mixture is crumbly. Sprinkle the topping over the muffins. Bake the muffins for 15 minutes.
Let muffins cool completely and serve plain or with butter, almond butter or jam. Enjoy!
