Preheat oven to 400°F. Line a 12-cup muffin pan with paper liners.
In a large bowl, whisk together flour, baking powder, flaxseed, and salt. Add berries and toss to coat.
In another bowl, combine milk, oil, Splenda Sugar Blend, eggs, and almond extract. Whisk until smooth.
Pour egg mixture into flour mixture and gently mix with a fork to moisten the dry ingredients. Don’t overmix (a few lumps in the batter are fine).
Spoon about ⅓ cup of batter into each of the prepared muffin cups.
Bake for 20–24 minutes, or until a wooden pick inserted into the center of a muffin comes out clean. Let cool for 5 minutes on a rack before serving warm.
