Creating Strawberry Brownies can be a straightforward process if you follow these easy steps:

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

2. Melt the Butter: In a medium saucepan over low heat, melt the butter slowly. Remove from heat and allow to cool slightly.

3. Mix Sugars and Butter: In a large bowl, combine the melted butter, granulated sugar, and brown sugar. Stir until well mixed.

4. Add Eggs and Vanilla: Add the eggs, one at a time, mixing thoroughly after each addition. Then stir in the vanilla extract.

5. Combine Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, salt, and baking powder until combined.

6. Incorporate Dry Ingredients: Gradually fold the dry ingredient mixture into the wet ingredients until fully combined. If desired, mix in the chocolate chips for added richness.

7. Add Strawberries: Gently fold in the sliced strawberries, ensuring they are evenly distributed throughout the brownie batter.

8. Spread and Bake: Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

9. Cool: Remove the brownies from the oven and let them cool in the pan for 15 minutes. Then, lift the brownies out of the pan using the parchment paper and allow them to cool completely on a wire rack.

10. Dust with Powdered Sugar: Once cool, dust the top with powdered sugar if desired for an elegant finish before slicing.
