Heat oven to 325°F. Coat doughnut pan with oil or nonstick spray and set aside.
In large bowl, whisk flour, cocoa powder, baking soda, and salt.
In small bowl, whisk buttermilk, brown sugar, egg (replacement), vegetable oil and vanilla extract until smooth.
Add milk mixture to flour mixture; whisk until fully blended.
Spoon batter into large Ziplock bag (and cut corner) or pastry bag and squeeze into pan until pan is about ⅔ full.
Bake 10 to 12 minutes, or until you can insert toothpick in center of doughnut and it comes out clean.
While doughnuts bake, blend strawberries until relatively smooth and add to a mixing bowl. Slowly stir in confectioner’s sugar until completely mixed.
Cool in pan 5 minutes, then turn over onto cooling rack.
Dip doughnut tops into glaze and enjoy!
