I'm pretty sure that everyone likes a thick and gooey brownie. I mean, if there are people out there who don't like big slabs of chocolatey goodness, then I've certainly never met them.
1/2 - 1cupdulce de lechedepending on how caramel-y you want it
Instructions
Pre-heat the oven to 350 degrees. Butter a 9x13 baking dish.
In small saucepan over low heat, melt butter completely. Stir in sugar and continue cooking for 1-2 minutes, stirring constantly. Do not allow sugar mixture to boil.
Pour butter mixture into a large bowl or stand mixer, beat in cocoa powder, eggs, salt, baking powder, espresso powder, and vanilla extract. Mix until well combined.
Stir in the flour and chocolate chips until well combined.
Pour half of the batter into the prepared pan. Drop spoonfuls of half of the dulce de leche over the top and swirl with a butter knife. Top with the remaining brownie batter and dulce de leche, swirling with a knife. Bake for about 30 minutes, until a tester comes out mostly clean. The edges should be set and the center should still look slightly moist, but not uncooked. Cool on a wire rack.
