These Peanut Butter Muffins are soft, fluffy, and bursting with rich peanut butter flavor. Perfect for breakfast, a quick snack, or even dessert, they’re simple to make, customizable, and a guaranteed family favorite!
Preheat oven to 350°F (175°C) and prepare muffin tins with liners or grease lightly.
In a bowl, whisk together flour, baking powder, and salt until combined.
In another bowl, mix peanut butter, sugar, milk, and egg until smooth and creamy.
Slowly add wet ingredients to dry ingredients. Mix gently until just combined—do not overmix.
Fill muffin cups two-thirds full with batter.
Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
Cool muffins in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Customize these muffins with chocolate chips, banana, granola, or a drizzle of honey for a fun twist. Store in an airtight container for up to 3 days, or freeze for longer freshness.
