Preheat & Prep: Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly. Do not skip preheating—rookie mistake.
Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, and salt. Keep it light and fluffy—no aggressive stirring needed.
Mix Wet Ingredients: In another bowl, whisk melted butter, eggs, milk, and vanilla until smooth. If it smells good already, you’re on the right track.
Combine: Pour wet ingredients into the dry ingredients and gently mix until just combined. Key tip: Lumps are fine. Overmixing is not.
Fold in Strawberries: Gently fold in the diced strawberries. Be kind to them—they bruise easily and will leak juice if bullied.
Fill the Muffin Cups: Scoop batter into muffin cups, filling about ¾ full. Sprinkle tops with coarse sugar if using.
Bake: Bake for 18–22 minutes, until tops are lightly golden and a toothpick comes out clean.
Cool & Enjoy: Let muffins cool for 5–10 minutes, then enjoy warm or at room temp. Or eat one immediately and pretend it “doesn’t count.”
