Step-by-Step Instructions
Ready? Let’s bake this beauty together:
Preheat the Oven
Set your oven to 375°F and grease an 8×8-inch baking dish with butter or non-stick spray. A glass dish works best for even browning.
Make the Crumb Topping
In a bowl, mix sugar, flour, and lemon zest. Add butter chunks and use a fork (or your fingers) to work them in until the mixture looks like coarse crumbs. Set aside—you’ll thank yourself later when the topping turns golden and crunchy..

Mix the Dry Ingredients
In a large bowl, whisk together flour, baking powder, and salt. Keep this bowl handy—you’ll be adding to it soon.

Cream the Butter & Sugar
In another bowl, beat the sugar and butter together until light and fluffy. This step traps air, which gives your cake a tender crumb. Add the egg, then the milk and lemon juice. Mix until smooth. Scrape down the sides so nothing gets left behind.

Combine Wet & Dry
Gradually add the dry ingredients to the wet mixture. Stir gently until just combined—overmixing can make the cake dense.

Fold in the Fruit
With a spatula, gently fold in the blueberries and lemon zest. The goal is to keep those berries whole and evenly distributed.

Top & Bake
Spread the batter evenly into your prepared dish. Sprinkle the crumb topping across the surface. Bake for 25–30 minutes, or until golden brown and a toothpick inserted in the center comes out clean.

Cool & Serve
Let the cake cool completely before slicing. If you’d like, dust with powdered sugar for a bakery-style finish.
Cooking Tips & Techniques
Flour the Berries – Toss blueberries lightly in flour before folding them in. This keeps them from sinking to the bottom.
Check for Doneness – Don’t rely only on time; ovens vary. A toothpick test is your best friend.
Use Fresh Lemon Zest – It packs way more flavor than bottled juice alone.
Recommended Equipment
8×8-inch baking dish – The perfect size for this buckle.
Mixing bowls – One for wet, one for dry, one for the topping.
Fork or pastry cutter – Ideal for crumb topping.
Hand or stand mixer – Helps cream butter and sugar to fluffy perfection.
Spatula – Gentle enough to fold in blueberries without breaking them.
