Preheat oven to 350°F and line a 9x13 inch baking dish with parchment paper. Place peanut butter in a microwave safe bowl and heat for 30 seconds or until peanut butter is warm and loose in texture. Repeat same process with jam. Set aside.

In a large bowl whisk together flour, baking powder, salt and sugar. In a separate bowl whisk together milk and eggs. Add wet ingredients to flour mixture and stir until just combined. Add melted butter and mix until incorporated.

Pour batter into prepared pan, spreading evenly. Dollop peanut butter and jam over surface of batter and use a dinner knife to swirl into batter. Bake for 15-18 minutes or until set.

Slice into squares and top with Greek yogurt, chopped peanuts and maple syrup.
