1-First Step: Prep the pan and oven Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal. This prevents sticking and simplifies cleanup. Spray lightly with cooking spray if desired. Mise en place: Measure all ingredients and cube cold butter. Cold butter ensures flaky texture in both crust and topping.

2-Second Step: Make the shortbread crust In a medium bowl, combine 1 cup flour, 1/2 cup sugar, and 1/2 cup cold butter. Use a pastry cutter or fork to mix until crumbly, like wet sand. It should hold together when pressed. Press evenly into the prepared pan, using the back of a measuring cup for a flat surface. Bake for 15 minutes until lightly golden. This par-bake sets the base without over-browning.

3-Third Step: Prepare the streusel topping While crust bakes, mix 3/4 cup oats, 1/2 cup shredded coconut, 1/2 cup flour, 1/3 cup sugar, 1/4 cup cold butter, and pinch of salt. Cut in butter until coarse crumbs form. Pro tip: Chill this mixture for 10 minutes in the fridge for larger crumbles that stay distinct. Avoid overmixing to keep texture crunchy. This coconut oat layer mimics linzer torte streusel.

4-Fourth Step: Add the apricot jam layer Remove crust from oven. Warm 1 cup apricot jam in microwave for 10-15 seconds to soften spreading. Stir to smooth, then spread evenly over hot crust. Use an offset spatula for thin, uniform coverage. The heat helps jam melt slightly for bubbling later. Opt for jam with fruit chunks like Bonne Maman for texture.

5-Fifth Step: Top and bake Sprinkle crumbly topping evenly over jam, pressing lightly in spots for adhesion. Return to oven and bake 25-30 minutes until topping turns golden brown and edges bubble. Rotate pan halfway for even baking. Test doneness: Jam should simmer visibly. Total bake time around 40 minutes.

6-Final Step: Cool and serve Cool in pan on wire rack for 30 minutes, then lift out using parchment. Chill 1 hour for clean cuts. Slice into 16-24 squares while slightly warm. Dust with powdered sugar. Serve at room temp for best flavor. Pairs with tea or ice cream. Store as noted below. These no bake apricot bars alternative? Chill crust instead, but baking enhances texture.
