Preheat the oven: Set to 375°F (190°C). Line 4 wells of a muffin tin with paper liners or grease lightly.

Mix dry ingredients: In a medium bowl, combine all-purpose flour, whole wheat flour, baking powder, baking soda, salt, and ground cinnamon. Stir in raisins and set aside.

Mix wet ingredients: In a separate bowl, whisk together milk, honey or maple syrup, egg, oil, and vanilla extract until smooth.

Combine batter: Pour the wet mixture into the dry mixture and stir gently with a spatula until just combined. Do not overmix; the batter should be slightly lumpy.

Fill muffin wells: Divide the batter evenly between the 4 prepared muffin wells, filling each about ¾ full.

Bake: Place in the preheated oven and bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the tin for 5 minutes, then transfer to a wire rack.

Prepare fruit: Rinse and slice fruit as needed. Divide between two bowls or plates.

Pour milk: Divide oat milk into two glasses.

Serve: Plate one muffin per person with fruit on the side. Serve with cold oat milk. Enjoy!
