Making Strawberry Crunch Brownie Bars is quite simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper.

2. Prepare Brownie Batter: In a medium saucepan, melt the unsalted butter over low heat. Remove from heat and stir in granulated sugar, eggs, and vanilla extract until smooth.

3. Combine Dry Ingredients: In a separate bowl, sift together flour, cocoa powder, salt, and baking powder. Gradually add this mixture to the butter mixture, stirring until fully combined.

4. Bake Brownies: Pour the brownie batter into the prepared baking pan. Spread evenly and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

5. Cool Brownies: Remove from the oven and allow to cool in the pan for about 15-20 minutes. Once cooled, lift the brownies out using the parchment paper and let them cool completely on a wire rack.

6. Prepare Strawberry Topping: In a medium bowl, combine the sliced strawberries, granulated sugar, and lemon juice. Toss gently and let sit for about 10 minutes to release juices.

7. Make Crunch Topping: In another bowl, mix together crushed graham crackers, coconut flakes, melted butter, and sugar until crumbly.

8. Assemble Bars: Once the brownies are completely cool, spread the macerated strawberries evenly over the brownie layer. Then, sprinkle the crunch topping generously over the strawberries.

9. Chill: Place the assembled bars in the refrigerator for at least 30 minutes to set before slicing.

10. Slice and Serve: Cut into squares and serve chilled or at room temperature.
