Fudgy brownies topped with a swirl of fresh balsamic strawberries. Rich chocolate pairs perfectly with a little tang and tartness.
Preheat oven to 350 degrees F.
Melt the butter and mix with yogurt in a large bowl. Add the sugar and beat with a hand mixer. Add in one egg at a time, beating well after each addition. Stir in the vanilla. In a medium bowl, whisk together the cocoa, flour, and salt. Add to the wet ingredients and use a spatula to mix together. Grease a 9x13 inch pan and pour batter into pan. Smooth the top and set aside.
In a small saucepan over medium heat, combine the strawberries, sugar, and 1 T balsamic vinegar. Bring to a simmer and cook, while smashing down the strawberries with a spatula. When the mixture has reduced a little, remove from heat and stir in the second T of balsamic vinegar. Add spoonfuls of strawberry mixture over the brownie mixture and swirl it in. The strawberry mixture should mostly remain on the top, so don't mix too much! Sprinkle the chocolate chips over the top and place in oven. Bake for 30-45 minutes or until toothpick comes out clean (make sure you aren't poking through a chocolate chip or it might not look clean!).
Remove from oven and allow to cool. Cut into squares and serve!
