Ingredients
Main Ingredients
- 142 g cold unsalted butter, divided and cut into pieces
- 200 g dark brown sugar, tightly packed
- 1 large egg (kept cold)
- 2 tsp vanilla extract
- ½ tsp fine sea salt
- ¼ tsp cinnamon powder
- ¼ tsp baking powder
- ¼ tsp baking soda
- 190 g all-purpose flour
- 85 g white chocolate (chips or chopped pieces)
- 75 g blueberry jam well mixed before use
Instructions
Preparation
- Preheat oven to 350°F (180°C). Prepare an 8×8-inch pan by greasing it and lining it with parchment paper leaving overhang for easy removal.
- Melt most of the butter (about 113 g) over medium heat, then continue cooking while stirring until it turns golden brown and smells nutty. Set aside.
- In a bowl, mix brown sugar with the remaining butter. Pour in the browned butter and whisk until combined, even if the texture looks slightly uneven.
- Add egg, vanilla, salt, and cinnamon, then whisk until the mixture becomes smooth and glossy.
- Mix in baking powder and baking soda. Gently fold in flour and white chocolate until no dry streaks remain.
- Spread the batter evenly into the prepared pan. Spoon blueberry jam on top and swirl it through the batter using a knife or skewer.
- Bake for about 25-27 minutes, until the surface is golden and the center still has a slight soft wobble.
- Allow to cool completely in the pan before lifting out using the parchment. Cut into squares once fully cooled and store in an airtight container.
Notes
Serve at room temperature with a dollop of whipped cream or a scoop of vanilla ice cream. Consider topping with crushed nuts or powdered sugar for presentation.
