Making Raspberry Brownie Parfaits involves several straightforward steps. Here’s how you can create this fantastic dessert:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking pan.

2. Melt Butter and Sugar: In a medium saucepan over low heat, melt the butter. Once melted, add granulated sugar and stir until well combined.

3. Add Eggs and Vanilla: Remove from heat. Let it cool slightly, then stir in the eggs, one at a time, mixing well after each addition. Add the vanilla extract and mix until smooth.

4. Mix Dry Ingredients: In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually add this mixture to the wet ingredients, stirring until just combined.

5. Bake the Brownies: Pour the brownie batter into the prepared pan. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

6. Cool the Brownies: Remove the brownies from the oven and allow them to cool completely in the pan. This will ensure they’re firm enough to cut.

7. Prepare the Whipped Cream: In a large mixing bowl, combine heavy whipping cream and powdered sugar. Beat with an electric mixer on medium speed until stiff peaks form.

8. Cut Brownies: Once the brownies are cool, cut them into small squares or rectangles for easy layering.

9. Layer the Parfaits: In serving glasses or bowls, layer brownie pieces at the bottom, followed by a layer of whipped cream, and then a layer of fresh raspberries. Repeat the layering until the glasses are filled, finishing with whipped cream and a scattering of raspberries on top.

10. Chill: Optionally, refrigerate the parfaits for about 15-30 minutes before serving to allow the flavors to meld.
