📝 Key ingredients
Read the tips below for success. Full ingredient list and step-by-step instructions are in the recipe card further down.
- Butter & oil: The combination gives both flavor and moisture. Use real unsalted butter for the best taste; a vegan butter can be substituted.
- Buttermilk: Store-bought buttermilk or cultured kefir work best. You can make a quick substitute by combining ¾ cup room-temperature milk (dairy or plant-based) with 2 teaspoons vinegar.
- Blackberries: Fresh or frozen berries are both fine. If using frozen, add them straight from the freezer — do not thaw. This recipe also works well with other berries such as blueberries or raspberries.
- All-purpose flour: For consistent results, weigh the flour. If you don’t have a scale, stir the flour, spoon it into the measuring cup, then level it off with a knife without packing.
Leftover buttermilk can be used to make scones, pancakes, or other baked goods.
👩🍳 How to make blackberry buttermilk muffins
Prep: Preheat the oven to 195°C (385°F). Line a 12-cup muffin tin with tulip-style or regular liners, or make DIY parchment liners using the method shown below.
Step 1: In a medium bowl, stir together the brown sugar, granulated sugar, flour, and salt for the crumble.
Step 2: Add melted butter and mix until the crumbs form. Set the crumble aside while you prepare the batter.
Step 3: Toss the blackberries with 1 teaspoon of flour to help prevent them from sinking during baking. Set aside.
Step 4: In a large bowl, whisk the eggs with the granulated sugar and salt until combined.
Step 5: Whisk in melted butter, oil, vanilla, lemon juice, and the buttermilk until the mixture is smooth.
Step 6: Sift the flour and baking powder over the wet ingredients and fold gently until the batter has no obvious dry streaks. Carefully fold in the flour-coated blackberries.
Step 7: Divide the batter among the prepared liners, filling them almost to the top for a nice dome. Generously sprinkle the crumble on each muffin.
Step 8: Bake for 18–22 minutes, until the tops are golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Allow to cool briefly before serving.
✔️ Expert tips
- Measure flour correctly: Weigh flour for the most reliable results. If using measuring cups, stir the flour, spoon it into the cup, then level off without packing.
- Don’t overmix: Small lumps are fine. Mix just until the dry streaks disappear to keep the muffins light and tender.
- Coat the berries: Tossing berries in a teaspoon of flour helps keep them from sinking to the bottom of the muffins.
- Fill the liners high: Fill the liners near the top to encourage tall, domed muffin tops.
- Avoid overbaking: Remove the muffins when they are golden and a toothpick comes out mostly clean to retain moistness.
🥄 Make ahead and storage
These muffins freeze well and are ideal for make-ahead breakfasts. Store in an airtight container or freezer bag for up to 2 months. Thaw and warm briefly so the crumble becomes crisp again.
At room temperature, store the muffins in an airtight container for up to 3 days.
❔ How to make DIY bakery-style muffin liners
DIY parchment liners are quick to make and give a bakery look. Cut twelve 4″–5″ square pieces of parchment. Place a square over an upside-down glass, press the sides to crease, then lift the parchment off and place it into the muffin tin. The liners will open further once batter is added.
Step 1: Cut parchment into squares and press each square over an inverted glass to form the crease.
Step 2: Place each molded square into the muffin tin. The liner may appear small until you add batter and it expands to fit the cup.
🍞 How to get the perfect dome on muffins
A thicker batter helps form a high dome because it provides more structure. Filling liners nearly full and baking at a relatively high temperature produces steam that lifts the tops quickly, giving a bakery-style dome. If your oven tends to run hot or cool, use an oven thermometer to confirm the actual temperature.
📖 Recipe FAQs
The oil helps keep the muffins moist while the butter adds rich, familiar flavor.
Yes — granulated sugar works, though brown sugar adds a deeper flavor and color.
Fill the liners almost to the top and bake at the suggested temperature. The higher initial heat produces steam that helps the tops rise.
Coating the berries in a bit of flour helps the batter cling to them. A thicker batter also reduces sinking.
Yes — blueberries, raspberries, diced apples, or sliced strawberries can be substituted using the same method.
Yes. Add frozen berries directly to the batter without defrosting.
Yes. Use the same instructions and fill the liners high for good domes.
