Preheat oven to 375°F and fill a muffin pan with liners or grease with non-stick spray.
In a medium bowl, whisk together 2 cups of flour, the baking powder, and salt.
In a large bowl, whisk together the vegetable oil, sugar, eggs, vanilla extract, almond extract (if using), and strawberry kefir.
Chop and measure the strawberries. Pat them dry if they're super juicy.Set aside ½ cup of the chopped berries. Coat 1½ cups of them in ¼ cup of flour.
Stir the dry ingredients into the wet ingredients until just a few flour streaks are visible.
Fold the flour-coated strawberries into the batter just until combined.
Fill the muffin liners about ¾ full with batter. Top with the remaining ½ cup of strawberries and optional coarse sugar.
Bake on the middle rack until a toothpick comes out of the center clean (about 20-25 minutes).
Once the muffins are cool enough to touch, transfer them to a wire cooling rack.
