Blackberry Lemon Crumb Bars
Crust Ingredients
- Butter – The heart of a good crust, giving it that rich, melt-in-your-mouth flavor.
- Brown sugar – Adds sweetness with a hint of molasses depth.
- Lemon zest – Brightens the whole dessert with a citrusy punch.
- All-purpose flour – The sturdy base for your dough.
- Baking soda – Keeps the crust from feeling too heavy.
- Salt – Brings out all the other flavors.
- Cinnamon – The perfect warm spice.
Filling Ingredients
- Granulated sugar – Sweetens the tart berries perfectly.
- All-purpose flour – Helps thicken the fruity filling.
- Fresh blackberries – Juicy pops of berry flavor in every bite.
- Lemon zest – Doubles down on the citrus flavor.
- Fresh lemon juice – Adds just the right tangy balance to the sweetness.

1. Heat oven to 350 F. Line an 8-inch square baking pan with parchment paper.
2. In a large mixing bowl, whisk together the butter, brown sugar, and fresh lemon zest thoroughly.
3. Add flour, baking soda, salt, and cinnamon and mix until the dry ingredients are fully incorporated.
4. Take 1 cup of the base mixture and set aside for later.
