1. Preheat oven to 350F. Line a 12-count muffin tin with cupcake liners, or you may make your own liners. Cut 5 inch x 5 inch parchment paper squares. Place the center of the square on bottom of glass, and using hands, firmly press parchment paper against sides of glass. Place the muffin liners in muffin tin. If they don’t stick down into the wells, don’t worry, the muffin batter will hold them down into the tin.

2. In a large mixing bowl, whisk together oil and sugars until combined. Add in the eggs and milk mix until combined. Add in the flour, baking soda, baking powder and salt and mix just until combined. Fold in the apples.

3. In a small bowl, add ingredients for streusel. Using a fork, press the butter into the dry ingredients, until pea sized morsels are formed.

4. In a small bowl whisk together cinnamon and sugar for cinnamon sugar swirl.

5. Scoop roughly 1 tablespoon muffin batter into prepared muffin tin/liners. Sprinkle cinnamon sugar mixture over batter. Evenly divide remaining batter over top of the cinnamon sugar mixture. Sprinkle the streusel over the muffins.

6. Bake in oven for 25-30 minutes, or until golden brown and a toothpick inserted into the center comes out clean.

7. In a small bowl, stir together ingredients for icing. Drizzle with icing. Serve and enjoy!
