Follow these steps to make your delicious Chocolate Covered Strawberry Brownies:

1. Preheat your Oven: Set your oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray or line it with parchment paper.
2. Mix Wet Ingredients: In a large mixing bowl, combine the melted butter and granulated sugar. Stir until well integrated. Add the eggs and vanilla extract, mixing until smooth.
3. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
4. Combine Mixtures: Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
5. Add Chocolate Chips: Fold in the chocolate chips until evenly distributed throughout the brownie batter.
6. Spread Batter: Pour the brownie batter into the prepared baking pan, spreading it evenly with a spatula.
7. Bake: Place in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out mostly clean (a few moist crumbs are okay).
8. Cool Brownies: Remove the brownies from the oven and set them aside to cool in the pan for about 15-20 minutes. Once cooled, transfer them to a wire rack to cool completely.
9. Prepare the Chocolate Coating: In a microwave-safe bowl, combine the semi-sweet chocolate and vegetable oil. Heat in 30-second intervals, stirring in between until the chocolate is smooth and melted.
10. Add Strawberries: Dip the sliced strawberries into the melted chocolate, ensuring they are fully coated. Allow any excess chocolate to drip off before placing them on a parchment-lined tray to set.
11. Top the Brownies: Once the brownies are completely cool, arrange the chocolate-covered strawberries on top of the brownies.
12. Final Chill: You may place the assembled brownies in the refrigerator for 10-15 minutes to help set the chocolate topping.

Now, your Chocolate Covered Strawberry Brownies are ready to be served!
