Add 1 1/4 cups unsweetened milk of choice, 1/2 cup chia seeds, 1/3 cup maple syrup, 1/2 cup creamy almond butter, and 1 teaspoon vanilla extract to a mixing bowl, then use a whisk to mix well.
Let that mixture rest for 20 minutes to soften the chia seeds.
When the mixture has finished resting, preheat the oven to 375 degrees Fahrenheit.
Add 1 cup whole wheat flour (spooned into the measuring cup, then leveled—not scooped), 2 teaspoons baking powder, 1/4 teaspoon ground cinnamon, and 1/4 teaspoon salt to a separate bowl, then mix well.
Transfer the dry ingredients into the bowl with the wet ingredients, then whisk to combine.
Add 1 cup fresh or frozen blueberries, then gently mix to combine.
Divide the batter evenly into 12 portions in a muffin pan lined with paper baking cups.
Bake for 22 minutes or until a toothpick inserted into the center of a muffin comes out looking clean.
Let the muffins cool to room temperature before removing from the pan and serving.
