In a small bowl mix together the egg, vanilla extract, almond extract, and half & half. Add this mixture all at once to the flour mixture. Stir slowly with a spoon until just combine. Gently mix in the diced strawberries.
Divide batter into the prepared muffin cups. Bake for 25 minutes or until a tester inserted in centre comes out clean. Sprinkle with powdered sugar.
