Strawberry Oatmeal Crumble Bars (Print Version)

# Ingredients:

→ Oatmeal Crumble

01 - 125 g all-purpose flour
02 - 100 g old-fashioned rolled oats
03 - 115 g unsalted butter, cold and diced or grated
04 - 65 g granulated sugar
05 - 65 g brown sugar, packed
06 - 1 teaspoon baking powder
07 - 0.25 teaspoon salt
08 - 0.5 teaspoon ground cinnamon

→ Strawberry Filling

09 - 300 g fresh strawberries, hulled and sliced or thawed frozen strawberries, well-drained
10 - 25 g granulated sugar
11 - 12 g brown sugar
12 - 2 teaspoons lemon juice
13 - 1 teaspoon finely grated lemon zest
14 - 60 g strawberry jam
15 - 8 g cornstarch (plus 1 extra teaspoon if using frozen strawberries)

# Instructions:

01 - Cut cold butter into small cubes or grate using a box grater. In a large bowl, combine flour, oats, granulated sugar, brown sugar, baking powder, salt, and cinnamon. Add the cold butter and blend with a pastry cutter or fork until the mixture forms pea-sized crumbs. Chill the crumble mixture in the refrigerator for at least 30 minutes.
02 - If using fresh strawberries, rinse and drain thoroughly; if using frozen, thaw completely and drain excess liquid. In a saucepan over medium heat, combine strawberries, granulated sugar, brown sugar, lemon juice, lemon zest, strawberry jam, and cornstarch. Bring to a gentle boil, then reduce heat and simmer, stirring, until thickened to a jam-like consistency, about 5–7 minutes. Set aside to cool slightly.
03 - Preheat oven to 175°C (350°F). Line a 20 x 20 cm (8-inch) square baking pan with parchment paper. Press about two-thirds of the chilled crumble mixture evenly into the base of the pan to form the crust. Bake the crust for 10–12 minutes, until pale golden.
04 - Spread the prepared strawberry filling evenly over the baked crust. Sprinkle the remaining crumble mixture evenly on top of the filling.
05 - Return pan to the oven and bake for 30–35 minutes, or until crumb topping is golden brown and filling is bubbling at the edges.
06 - Allow bars to cool completely in the pan. For cleaner slices, chill in the refrigerator or freezer for 15 minutes before cutting. Slice into squares or bars.

# Notes:

01 - Chilling the bars before slicing ensures neater portions.
02 - Avoid overbaking to keep the crust and topping tender.
03 - For a softer texture, serve slightly warm; for firmer bars, chill before cutting.
04 - Optionally, serve with a scoop of vanilla ice cream or a drizzle of melted chocolate.
05 - Store in an airtight container at room temperature for 2 days, refrigerate up to 5 days, or freeze for up to 2 months.
