1-First Step: Prep the pan and oven Start by heating your oven to 350 degrees Fahrenheit. Spray egg-shaped silicone molds with nonstick spray so the brownies release easily after baking. If you do not have egg molds, you can also bake the brownies in a pan and cut egg shapes later, but the mold gives the cleanest result for this easy fudgy chocolate treat.

2-Second Step: Mix the brownie batter Prepare the brownie batter according to the package directions using the 18.3 ounce box fudgy brownie mix, 2 large eggs, 2/3 cup vegetable oil, and 3 tablespoons water. Stir just until combined. Overmixing can make brownies tougher, so stop once the batter looks smooth.

3-Third Step: Fill the molds Spoon the batter into each mold cavity until it is about 3/4 full. This leaves enough room for the brownies to rise without spilling over. Tap the mold gently on the counter if needed to settle the batter and remove large air pockets.

4-Fourth Step: Bake until just set Bake the brownies for about 22 minutes, or follow the package directions if your mix suggests a slightly different time. At 350 degrees Fahrenheit, they should be done when a toothpick inserted in the center comes out with moist crumbs. That is the sweet spot for fudgy brownies, not dry cake-like ones.

5-Fifth Step: Shape the centers While the brownies are still warm, gently press a small cavity into the center of each one. You can use the back of a spoon or a small measuring spoon. Do this carefully so the brownies do not crack. Pressing them while warm helps keep the shape smooth and neat.

6-Sixth Step: Cool completely Let the brownies cool fully before adding frosting. This matters because warm brownies can melt the filling and make the swirl slide around. Cooling also helps the texture firm up, which makes the final look much cleaner.

7-Seventh Step: Make the frosting In a bowl, beat the softened cream cheese, powdered sugar, and vanilla until smooth. You can use a hand mixer or stand mixer for this step. If you want a stronger holiday look, tint the frosting with a little food gel color before piping.

8-Eighth Step: Pipe the frosting Transfer the frosting to a piping bag fitted with a 1M tip. Pipe a swirl into the center cavity of each brownie so it looks like the filling of a deviled egg. If you do not have a piping bag, you can spoon the frosting in, but the swirl tip gives the prettiest finish.

9-Ninth Step: Add the finishing touch Top each brownie with 1 to 2 teaspoons festive sprinkles. Then place the finished brownies on a deviled egg tray for a cute display. Serve them right away, or chill them briefly if you want the frosting to firm up a little more.
