Preheat the oven to 375° Fahrenheit.
In a large mixing bowl, mix together all of the dry ingredients, except for the ones for the crumb topping. Make a well in the center to add the wet ingredients in.
Add in the eggs, milk, applesauce, vanilla, and almond extract. Stir until everything is incorporated-- don't worry about getting all the lumps out.
Stir in the blueberries.
Spray the bottoms of a 12 cup muffin tin (I recommend Baker's Joy spray), and divide the muffin batter among the cups.
Make the crumb topping by mixing the oats, sugar, butter, and cinnamon together in a small bowl.
Sprinkle the topping evenly on all of the unbaked muffins.
Bake for about 18 minutes.
