Preheat and prep
Preheat your oven to 190°C / 375°F. Line a muffin tin or grease it well. Future you will thank you.
Mix the dry stuff
In a large bowl, whisk together flour, sugar, baking powder, and salt. Keep it light—no aggressive mixing needed.
Mix the wet stuff
In another bowl, whisk melted butter, eggs, milk, and vanilla. It should look smooth and friendly, not chaotic.
Bring it together
Pour the wet ingredients into the dry ones. Stir gently until just combined. Overmixing is the enemy of fluffy muffins.
Add raspberries carefully
Gently fold in raspberries. If using frozen, don’t thaw them—unless you enjoy pink batter and regret.
Fill the muffin cups
Divide batter evenly, filling each about ¾ full. Sprinkle coarse sugar on top if you’re feeling fancy.
Bake and wait (impatiently)
Bake for 18–22 minutes, until tops are golden and a toothpick comes out mostly clean. Cool slightly before inhaling.
