• Turn the oven on and make brownie batter according to package instructions. When the batter is stirred well and complete, pour on to a small sheet pan and press batter down flat with a spatula or your fingers until the batter is smooth, and spread out over the entire sheet pan. Cook according to brownie package instructions.
• When the brownies are done, take out of oven and set aside until completely cooled off.
• While you are waiting for the brownies to cool off, prep the berries and frosting.
• Rinse the blueberries and strawberries.
• Slice the strawberries long ways from the top down to the bottom tip of the strawberry, discard the side parts (the middle is the best to use to make a beautiful strawberry pattern, on your dessert pizza from the lines of the strawberry).

To make the frosting:

• Melt butter in a microwave-safe dish and microwave until melted (about 10 seconds or so).
• Transfer to a bowl (or electric mixer), on low, and beat with cream cheese and vanilla extract until nearly fluffy. This will take about 5 minutes. Gradually stir in confectioner's sugar into cream cheese mixture to make a smooth frosting.
• Store in refrigerator.

Dessert Pizza:

• To finish your dessert pizza, spread your homemade frosting thick on to your pizza (about 1/2 in.). Place your blueberries in a 6 by 8 rectangle shape in the left upper corner of the frosted brownies. Next, make 4 strawberry stripes, starting at the very top of the sheet pan and working your way down.
• Eat immedietly!
