Why You’ll Love This Recipe

• • Bakery-Style Dome – The two-stage baking method creates that tall, dramatic cracked top straight out of a professional kitchen
• Incredibly Moist Crumb – Greek yogurt, buttermilk, butter, and oil together produce a tender interior that stays soft for days
• Bold Lemon Flavor – Zest from two full lemons runs through both the batter and the crumble for bright citrus in every layer

Serving Suggestion

These muffins are best enjoyed about 15 minutes out of the oven, when the crumble is still crisp and the blueberries are warm and jammy. Serve alongside a strong coffee or Earl Grey tea, which pairs beautifully with the lemon. For an extra indulgent touch, slice a warm muffin in half and add a small spread of salted butter, it melts straight into the crumb and takes the whole thing to another level.

Pro Tips for Perfect Muffins

• Do Not Overmix – Fold just until no dry flour remains to keep the crumb light and tender
• Fill the Cups Generously – Fill each jumbo cavity almost to the top for that signature tall dome
• Use Fresh Blueberries – They hold their shape better; if using frozen, fold them in straight from the freezer without thawing
• Zest Before Juicing – Always grate the lemon before cutting and squeezing it
• Rest Before Removing – Let muffins cool in the tin for at least 10 minutes before turning out

Ingredient Notes

• Greek Yogurt – Full-fat gives the best result, adding creaminess, tang, and structure to the batter
• Buttermilk – Reacts with baking soda to create lift and keeps the crumb soft. Substitute with regular milk plus one tablespoon of lemon juice if needed
• Butter – Softened for the batter, cold and cubed for the crumble so the topping stays chunky
• Lemon Zest – Most of the lemon flavor comes from the zest, not the juice — do not reduce the quantity
• Blueberries – Toss in a teaspoon of flour before folding in to keep them from sinking to the bottom
• Crumble Topping – Rub cold butter into the dry ingredients until rough and clumpy.

Instructions

Preheat the oven

Set to 220°C. Line a jumbo muffin tin with large liners or grease each cavity generously.

Make the crumble

Combine flour, sugar, and lemon zest. Rub in cold butter until rough and clumpy. Refrigerate while you make the batter.

Mix the wet ingredients

Beat softened butter and sugar until pale. Add eggs one at a time, then stir in yogurt, buttermilk, oil, vanilla, lemon juice, and lemon zest.

Add the dry ingredients

Sift in flour, baking powder, baking soda, and salt. Fold gently until just combined, do not overmix.

Fold in the blueberries

Toss blueberries in a teaspoon of flour, then fold carefully into the batter.

Fill the tin

Divide batter between 8 jumbo cups, filling almost to the top. Add crumble generously over each muffin and press lightly to adhere.

Bake at high heat

Bake at 220°C for exactly 6 minutes to create the dome.

Reduce and finish

Without opening the oven, reduce to 180°C and bake for 30 to 35 minutes until golden and a toothpick comes out clean.

Cool and serve

Rest in the tin for 10 minutes, then transfer to a wire rack. Serve warm for the best experience.
