Preheat oven to 180°C / 350°F (160°C fan forced).
Place the flour in a medium sized bowl. Add brown sugar and baking powder. Mix it through, and then add melted butter. Mix well – the mixture will resemble crumbs. Reserve one cup of the biscuit mixture for the topping and set aside.
Top the crumble base with strawberry jam, then the fresh chopped strawberries.
Cut them into slices, and then serve at room temperature. This recipe yields 16 bars (sized 2 cm by 2 cm). Nutrition information is keeping in mind one bar for one person.
The jam bars can be stored in an airtight container for 3 – 4 days in a cool place. In case the temperature is hot, they are best kept in the fridge.
