Get Ready: Preheat your oven to 350°F (175°C). Lightly grease a 24-cup mini muffin pan and dust it with a little flour.
Mix Brownie Batter: In a medium mixing bowl, combine the brownie mix, eggs, oil, and water. Stir until everything is just combined and no dry spots remain – avoid overmixing for tender brownies!
Bake Brownies: Spoon the batter into each muffin cup, filling them about ¾ full. A 1-inch cookie scoop works perfectly to keep them uniform. Bake for approximately 12 minutes.
Cool Brownies: Remove the pan from the oven and let the brownie bites cool in the pan on a wire rack for 15 minutes. Then, gently remove them from the pan (a small fork can help ease them out) and place them directly onto the wire rack to cool completely. This is key before decorating!
Whip Cream: While the brownies cool, use a mixer with a wire whip attachment to whip the heavy cream in a large mixing bowl until soft peaks form.
Stabilize Cream: Add the instant vanilla pudding mix to the whipped cream and continue whipping until stiff peaks form. Be careful not to overmix, or it can become grainy. This pudding helps the cream hold its shape!
Prepare for Decorating: Transfer the whipped cream into a piping bag fitted with a #21 star tip (or any small star/round tip you have). Prepare your strawberries by cutting off the green tops and slicing a tiny bit off the pointed end to create a flat base, ensuring they sit nicely.
Assemble Santa Hats: Pipe a generous layer of whipped cream onto the top of each cooled brownie bite. Gently place a prepared strawberry, cut-side down, onto the cream layer. Finish by piping a small dollop of cream on the very tip of the strawberry to create the "pom-pom" of the Santa hat.
Serve & Enjoy: Serve these adorable, festive bites immediately, or store them in an airtight container in the refrigerator until you're ready to share the holiday cheer!
