📝 Key ingredients
Read through the tips for success below. Full ingredients and steps are in the recipe card.
- Butter & oil: Butter adds flavor while oil keeps the muffins moist. Use real butter for best taste; vegan butter can be substituted.
- Buttermilk: Store-bought buttermilk or kefir works best. To make a quick substitute, combine ¾ cup milk (or plant milk) with 2 teaspoons vinegar and let sit for a few minutes.
- Blackberries: Fresh or frozen blackberries both work; keep frozen berries frozen when adding to the batter. You can swap blueberries or raspberries if you prefer.
- All-purpose flour: For consistent results weigh your flour. If you don’t have a scale, stir the bag, spoon flour into the cup, and level off without packing.
👩🍳 How to make blackberry buttermilk muffins
Prep: Preheat the oven to 195°C (385°F). Line a 12-cup muffin pan with tulip or regular liners, or make DIY parchment liners (instructions below).
Step 1: Make the crumble by combining brown sugar, granulated sugar, flour, and a pinch of salt. Stir in melted butter until the mixture forms coarse crumbs. Set aside.
Step 2: Toss the blackberries with 1 teaspoon of flour to help prevent them from sinking in the batter.
Step 3: In a large bowl whisk together eggs, granulated sugar, and salt until combined. Add melted butter, oil, lemon juice, buttermilk, and vanilla; whisk until smooth.
Step 4: Sift the flour and baking powder over the wet ingredients and fold gently until no dry streaks remain. Fold in the flour-coated blackberries carefully so they don’t break up too much.
Step 5: Fill each liner nearly to the top with batter to encourage domes. Generously sprinkle the crumble over each muffin.
Step 6: Bake 18–22 minutes, until the tops are golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Cool slightly and serve.
✔️ Expert tips
- Weigh your flour: A kitchen scale gives the most consistent results. If measuring by cup, stir the flour, spoon it into the cup, and level off without packing.
- Don’t overmix: Fold until flour streaks disappear; a few lumps are fine and keep the muffins tender.
- Coat berries in flour: This helps the fruit stay suspended in the batter instead of sinking.
- Fill liners high: Filling near the top encourages tall, bakery-style domes.
- Avoid overbaking: Remove muffins as soon as they are golden and a toothpick shows a few crumbs to keep them moist.
🥄 Make ahead and storage
These muffins freeze well—store in an airtight container or freezer bag for up to 2 months. At room temperature, keep in an airtight container for up to 3 days. Reheat briefly to restore the crumble’s crispness.
❔ How to make DIY bakery-style muffin liners
DIY parchment liners are quick to make and create a pretty tulip shape. Cut twelve 4″–5″ squares of parchment. Press each square over an upside-down glass to crease the sides, then transfer into the muffin tin. The liners will settle into shape once you add batter.
🍞 How to get the perfect dome on muffins
A thicker batter and a higher initial oven temperature help create steam that lifts the tops for tall domes. Filling liners nearly to the top gives more batter to rise above the rim. If your oven runs hot or cool, use an oven thermometer for accurate baking.
