Anna Louise A truly good blueberry muffin is one of the most satisfying things in all baking. It has a domed top — properly domed, the kind that rises above the paper case and catches the eye — with a slightly crunchy sugar surface.
Inside, the crumb is light and open, not dense or cakey, with blueberries distributed throughout that burst during baking and give pockets of jammy, vivid, slightly tart fruit in every bite.
The mistake people most often make with muffins is overmixing. The batter should be mixed as briefly as possible — the dry ingredients folded into the wet with the minimum number of strokes to just combine them.
Lumps in the batter are completely correct. A smooth muffin batter gives a dense, tough muffin. A lumpy, barely combined muffin batter gives a light, open crumb that is completely wonderful.
I make these with both fresh and frozen blueberries — frozen blueberries go in from frozen and give a slightly more vivid colour bleed into the surrounding crumb, which is beautiful. Fresh blueberries give a slightly more defined berry in the finished muffin. Both are excellent.
Ingredients for Mary Berry Blueberry Muffins (Makes 12)
For the Muffins
- 300g plain flour, sifted
- 150g golden caster sugar
- 2 tsp baking powder
- ½ tsp bicarbonate of soda
- ½ tsp fine salt
- 1 tsp ground cinnamon — gives warmth that suits blueberry beautifully
- 2 large eggs, at room temperature
- 200ml whole milk
- 100ml sunflower oil — gives a lighter, more open crumb than butter
- 1 tsp vanilla extract
- Finely grated zest of 1 unwaxed lemon — gives brightness that lifts the blueberry
- 250g fresh or frozen blueberries — plus extra for pressing into the tops
For the Crunchy Sugar Topping
- 2 tbsp demerara sugar — scattered over each muffin before baking
- Or 2 tbsp granulated sugar mixed with ¼ tsp ground cinnamon
How to Make Mary Berry Blueberry Muffins
Step 1 — Preheat and Prepare
Preheat your oven to 200°C / 180°C fan / Gas 6. Line a 12-hole muffin tin with paper muffin cases.
Step 2 — Combine the Dry Ingredients
Sift the flour, caster sugar, baking powder, bicarbonate of soda, salt, and cinnamon into a large bowl. Stir briefly to distribute.
Step 3 — Combine the Wet Ingredients
In a separate large jug, whisk together the eggs, whole milk, sunflower oil, vanilla extract, and lemon zest until just combined.
Step 4 — Bring Together
Pour the wet ingredients into the dry ingredients. Fold with a large spatula — ten to twelve strokes maximum. Stop the moment no dry flour is visible. The batter will look lumpy and slightly rough. This is exactly correct. Do not be tempted to smooth it.
Step 5 — Add the Blueberries
Fold the blueberries through the batter with two to three gentle strokes. If using frozen blueberries, fold them in directly from the freezer — defrosted blueberries bleed dramatically into the batter.
Step 6 — Fill and Top
Divide the batter between the twelve muffin cases — filling each case to approximately three-quarters full. The batter should dome slightly above the rim of each case before baking.
Press two or three extra blueberries into the top of each muffin — they give additional fruit on the top and look beautiful once baked. Scatter the demerara sugar generously over each muffin top.
Step 7 — Bake
Bake for 20 to 24 minutes until the muffin tops are deeply golden, the sugar has caramelised slightly, and a skewer inserted into the centre of a muffin comes out clean.
Leave in the tin for five minutes. Transfer to a wire rack. Serve warm — blueberry muffins at their best are still slightly warm from the oven.
My Top Tips For Best Mary Berry Blueberry Muffin
Fold the batter with ten to twelve strokes — then stop. This is the single most important instruction in every muffin recipe. Overmixed muffin batter develops gluten and gives a dense, rubbery, tunnel-filled crumb. Ten to twelve folds — stopping with lumps still visible — gives a light, open, properly domed muffin. Count the strokes if it helps.
Oil rather than butter gives the lighter crumb. Butter gives a richer, slightly denser muffin. Oil gives a lighter, more open crumb. For blueberry muffins — where the fruit and the crumb together are the point — oil is the better choice.
The lemon zest is the detail that makes the blueberries more vivid. Lemon and blueberry is one of the great flavour combinations — the citrus sharpness makes the blueberry taste more of itself. One lemon’s worth of zest in the batter gives a brightness throughout that makes these muffins noticeably better than those without.
Use frozen blueberries directly from the freezer. Defrosted blueberries release their juice before going into the batter and can colour the entire mix a murky purple-grey. From the freezer, they hold their shape during mixing and burst during baking, giving vivid pockets of blue-purple in a golden crumb.
Fill the cases generously. Three-quarters full in the case gives a muffin with a pronounced dome that rises above the paper. Half full gives a flat-topped, slightly mean-looking muffin. The dome is the visual signature of a good muffin.
Serving Suggestions
Warm from the oven with a cup of coffee — the finest breakfast or mid-morning combination. At room temperature as a snack. Split and spread with a little cold salted butter — simple and completely wonderful.
How to Store Mary Berry Blueberry Muffin
At room temperature: Store in an airtight container for up to 3 days. Warm briefly in a 160°C oven for five minutes before eating on day two or three.
In the freezer: Freeze in individual bags for up to 3 months. Defrost at room temperature for one hour or warm from frozen in a 180°C oven for twelve minutes.

Notes
Frequently Asked Questions
Can I use self-raising flour instead of plain flour and baking powder?
Yes — replace the 300g plain flour and 2 tsp baking powder with 300g self-raising flour. Keep the bicarbonate of soda.
Can I add a cream cheese filling?
Yes — place a teaspoon of batter in each case, add a small spoonful of sweetened cream cheese (cream cheese beaten with a little sugar and vanilla), cover with remaining batter, and bake as directed. The cream cheese centre is completely wonderful.
Can I use raspberries instead of blueberries?
Yes — fresh raspberries (not frozen — they are too fragile and break apart during folding) give a vivid, sharp alternative. Fold in very gently with two strokes only.
Why are my muffins flat rather than domed?
The most common causes are: overmixed batter, too little baking powder, or an oven that was not sufficiently preheated. All three affect the rise. Check the baking powder is fresh, preheat thoroughly, and count your mixing strokes.
