These rolo brownies are a chewy, fudgy chocolate brownie loaded with bits of toffee pieces and rolo candies. They're rich, decadent and incredibly delicious!
Preheat oven to 350 F. Line a 8x8 pan with parchment paper and spray.
Start by melting the butter and chocolate chips together in the microwave. I start with 30 seconds and then stir, continue in 15 second intervals until melted.
In a medium mixing bowl, mix melted butter/chocolate with oil and both sugars. Add the eggs, yolk and vanilla and mix again for about 1-2 minutes.
Whisk in baking powder, salt, flour and cocoa powder. Fold in toffee bits. Pour batter into prepared pan and then sprinkle the top of the batter with cut rolo's.
Bake for about 30-35 minutes. You want the edges to start to pull away from the sides of the pan and darken, and a toothpick inserted in the middle to come out clean. Sprinkle with sea salt if you like. Allow to completely cool before cutting into.
Notes
I have made these with gluten free flour and they turned out perfect.You can skip the toffee bits if you don't have them, or sub in chocolate chips.I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
