Ingredients Needed

Blueberries. Fresh or frozen both work. If using frozen, add them straight from the freezer—do not thaw. Coat frozen berries carefully in a little flour before folding them into the batter to avoid colour bleeding and soggy muffins.

Sorghum flour. A mild whole grain flour that blends smoothly with other gluten-free flours and contributes a pleasant texture.

Almond flour. Use blanched, finely ground almonds (often labelled “ground almonds” in some supermarkets). Almond flour gives density and structure, helping the batter suspend the blueberries.

Cassava flour. A neutral, starchy flour that helps bind the muffins without adding strong flavour.

Greek yoghurt. Thick Greek yoghurt adds moisture, a touch of tang, and helps create the thicker batter needed to hold the fruit in place.

Unsalted butter. Use melted butter in the batter and room-temperature butter in the streusel so you can control the salt and achieve the right texture.

Brown sugar and caster sugar. A mix of sugars gives the best balance of flavour and texture: brown sugar for moisture and caramel notes, caster (or fine granulated) sugar for structure.

Eggs, vanilla, baking powder, bicarbonate of soda and salt. Standard baking essentials that provide lift, flavour and balance. Check that baking powder is gluten-free if required.

How To Make Gluten-Free Blueberry Muffins

The following section gives a concise step-by-step method. For full quantities and timings see the recipe card below.

Start by preparing the streusel: whisk together the streusel flours, brown sugar and a pinch of salt. Rub in the softened butter with your fingertips until the mixture resembles coarse breadcrumbs and set aside.

For the muffins, whisk the sorghum, almond and cassava flours with baking powder, bicarbonate of soda and salt. In a separate bowl, beat the caster and brown sugars with the eggs, Greek yoghurt, melted butter and vanilla until smooth. Combine wet and dry ingredients to form a thick batter.

Toss the blueberries with a small amount of the reserved dry mix so they’re lightly coated. This helps prevent them sinking. Fold the berries gently into the batter so they remain whole and evenly distributed.

Spoon the batter into lined muffin tins, add a couple of extra blueberries to the top of each muffin for appearance, then sprinkle the streusel evenly over the tops. Bake briefly at a high temperature for five minutes to encourage lift, then reduce the oven temperature and continue baking until golden and cooked through.

Tips & Troubleshooting

• Measure melted butter after melting; a little is lost during melting and this keeps quantities accurate.
• Coat blueberries in reserved flour to prevent them sinking and to avoid colour bleeding.
• If using frozen berries, keep them frozen until ready to add to the batter and toss in the flour while still frozen.
• Pressing a few extra berries into the top of each muffin before adding streusel makes them visible after baking and adds a fresh burst of fruit on top.
• Remove muffins from the tin as soon as they are cool enough to handle to stop residual heat from over-baking the edges.
• For crunchier streusel, chill it briefly in the freezer while you prepare the batter so it holds its shape during baking.

Recipe Variations

Lemon Blueberry Streusel Muffins: Add the zest of 2 lemons to the batter and drizzle each muffin with a simple lemon glaze after baking for a bright, citrus lift.

Dairy-Free option: Replace the butter in the batter with neutral oil (such as olive oil) and use a plant-based yoghurt in place of Greek yoghurt. Use a tablespoon of oil in the streusel instead of room-temperature butter for a dairy-free streusel.

Mixed Berry Streusel Muffins: Substitute frozen mixed berries for the blueberries for a different berry profile and colour.
