Preheat the oven to 425 degrees Fahrenheit. Greased a 9×13 rimmed sheet pan with butter or nonstick spray, making sure to cover the entire pan.
Next, make a simple batter. To do this, combine flour, brown sugar, granulated sugar, baking powder, and salt in a large mixing bowl.
Then, add eggs, milk, unsalted butter, and vanilla extract. Whisk until all ingredients are combined.
Pour the pancake batter onto the baking sheet. Tap the pan a few times until the batter is evenly distributed. And now for the fun part!
Make a mental visual division in the batter and arrange your desired toppings on top. I divided the space into six sections. I swirled some raspberry jam into the batter for the first one. To make this, combine one tablespoon of jam with a teaspoon of water and stir. This will make the jam slightly more liquid. Then, using a toothpick, create marble-like patterns. Have some fun with it.
For the second section, I added blueberries, which are my favorites. For the third section, I used mini chocolate chips and crushed some of those chips for the fifth section. Lastly, I combined unsalted butter,(melted) cinnamon, and brown sugar for my last two sections. I did enjoy the last two with a cup of hot coffee the next day.
Place the sheet pan in the oven and bake for 15-20 minutes. Using a cookie cutter, trace those squares and serve with your choice of syrup.
