Ingredients (makes 12 standard muffins or 6 jumbo)Dry ingredients2 1/2 cups (315 g) all-purpose flour1 cup (200 g) granulated sugar2 1/2 tsp baking powder1/2 tsp baking soda1/2 tsp fine saltWet ingredients2 large eggs, room temperature1 cup (240 g) sour cream (or full-fat Greek yogurt)1/2 cup (120 ml) neutral oil (canola/vegetable)1/3 cup (80 ml) milk (any kind; buttermilk is great too)2 tsp vanilla extractZest of 1 lemon (optional but excellent with blueberries)Blueberries2 cups (about 300 g) blueberries, fresh or frozen1 tbsp flour (to toss with blueberries)Optional “bakery top” finish2–3 tbsp coarse sugar (or regular sugar) for sprinkling2 tbsp melted butter for brushing tops (optional)Optional lemon glaze (very good if you like a sweet finish)3/4 cup (90 g) powdered sugar1–2 tbsp lemon juice (or milk)1/2 tsp vanilla (optional)EquipmentMuffin pan (12-cup)Paper liners (optional)Mixing bowls + whiskSpatulaIce-cream scoop or 1/3 cup measure (for easy portioning)Step-by-step Instructions1) Prep the oven and panHeat oven to 425°F (220°C).Line a muffin tin with liners or grease well.If your oven runs hot, place a rack in the middle (not too close to the top heating element).Why this helps: Starting hot gives you that tall “dome” like a bakery muffin, then you’ll lower the temperature to bake the centers gently.2) Mix dry ingredientsIn a large bowl, whisk together:flour, sugar, baking powder, baking soda, and salt.Whisking evenly prevents “pockets” of baking powder and helps the muffins rise uniformly.3) Mix wet ingredientsIn a second bowl, whisk until smooth:eggs, sour cream, oil, milk, vanilla, and lemon zest (if using).Sour cream (or Greek yogurt) is the secret for a tender, moist crumb that stays soft even the next day.4) Combine wet + dry (don’t overmix)Pour wet mixture into the dry bowl.Fold together with a spatula just until you don’t see dry flour.Important: A few small lumps are fine. Overmixing makes muffins tough and can create tunnels inside.5) Add blueberries without turning the batter purpleToss blueberries with 1 tbsp flour (this helps them stay suspended instead of sinking).Gently fold blueberries into the batter.If using frozen blueberries: Don’t thaw them. Fold them in straight from frozen to reduce streaking.6) Rest the batter (optional but recommended)Let batter sit 10–15 minutes at room temperature.This short rest hydrates the flour and often gives a taller rise.7) Fill the muffin cups highScoop batter into prepared pan:Fill cups nearly to the top for tall bakery-style muffins.Sprinkle coarse sugar on top for a crisp, crackly finish.8) Bake with the “high-then-low” methodBake at 425°F (220°C) for 5 minutes.Without opening the oven, reduce heat to 350°F (175°C).Continue baking:12–16 minutes for standard muffins20–26 minutes for jumbo muffinsMuffins are done when:tops are deep golden, anda toothpick comes out clean or with a few moist crumbs (not wet batter).9) Cool properly (prevents soggy bottoms)Let muffins cool in pan 5 minutes.Transfer to a wire rack to cool.If you leave them too long in the hot pan, steam can soften the bottoms.Optional FinishesLemon glaze (pretty + crowd-pleasing)Whisk powdered sugar with lemon juice until thick but pourable.Drizzle over fully cooled muffins.Warm-butter topsBrush muffin tops lightly with melted butter while warm for an extra rich, “bakery” feel.Flavor Variations (choose one)Blueberry Streusel: Top with a crumble of 3 tbsp flour + 3 tbsp sugar + 2 tbsp cold butter (pinched into crumbs) + pinch of salt/cinnamon.Blueberry-Lemon Poppy: Add 1 tbsp poppy seeds + extra lemon zest.Blueberry Cream Cheese: Drop a small cube (or spoonful) of sweetened cream cheese into the center of each muffin before baking.Storage & Make-AheadRoom temp: Store in a container (not airtight-sealed tight) for up to 2 days.Fridge: Up to 5 days (warm 10–15 seconds in microwave to soften).Freeze: Wrap well and freeze up to 2–3 months. Thaw at room temp or microwave briefly.Troubleshooting (quick fixes)Muffins didn’t rise much: Make sure baking powder is fresh; use the 425°F старт and fill cups higher.Dense/tough texture: Batter was overmixed—fold only until combined.
