Making Chocolate Almond Butter Swirl Muffins is a breeze when you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a mixing bowl, whisk together the all-purpose flour, whole wheat flour, baking powder, baking soda, and salt until combined.
3. Combine Wet Ingredients: In another bowl, whisk together the granulated sugar, brown sugar, egg, milk, almond butter, vegetable oil, and vanilla extract until everything is smooth.
4. Combine Mixtures: Pour the wet ingredients into the bowl of dry ingredients. Stir gently until just combined, being careful not to over-mix. It’s okay if there are a few lumps.
5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips, ensuring an even distribution throughout the batter.
6. Fill Muffin Tins: Divide the batter evenly among the muffin cups, filling each about ⅔ full.
7. Create Swirls: If desired, drop spoonfuls of additional almond butter on top of the batter in each muffin cup. Use a toothpick or knife to swirl it into the batter gently.
8. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes. Muffins are done when a toothpick inserted into the center comes out clean.
9. Cool: Remove the muffins from the oven and let them cool in the tin for about 5 minutes before transferring them to a wire rack to cool completely.
