Luxury Chocolate Brownies using Ooni Halo Pro

Originally created in late 19th century America, over the years Chocolate Brownies evolved to include chocolate chips for added sweetness. This recipe honors that evolution, combining the decadence of a rich dark chocolate base with the indulgence of layered white and milk chocolate chips. The end result offers a mix of textures and flavors with every bite – gooey and fudgy, with crispy edges and pockets of molten chocolate.

Luxury Chocolate Brownies using Ooni Halo Pro
  1. Preheat your oven to 325°F Fan / Gas Mark 3 / 170°C. Grease and line a 13x10-inch cake tin (similar to the Ooni Detroit-Style Pizza Pan).
  2. Melt the chocolate and butter. Place the chocolate and butter in a medium saucepan and gently heat until melted. Leave to cool for 10 minutes.
  3. Add sugar, salt and vanilla. Attach the silicone beater to the mixer, and add the sugar, salt and vanilla to the bowl. Pour the melted chocolate and butter into the bowl. Mix at 50% power (195 RPM) for 1 minute. Pause the mixer, this helps to not to overmix the ingredients, and allows time for you to prepare for the next step. Overmixing the ingredients would put too much air in and affect the end results. 
  4. Combine eggs. Turn the mixer up to 70% power (255 RPM) and add the eggs one at a time. Normally about 50-60 seconds between eggs. Pause the mixer after all the eggs are added.
  5. Stir in flour and cocoa powder. Sift the flour and cocoa powder into the bowl. Mix at 70% power (255 RPM) for 1 minute. Pause mixer.
  6. Add chocolate chips. Add white and milk chocolate chips. Mix at 70% power (255 RPM) for 30 seconds. Pause mixer. 
  7. Empty into baking tin. Using a spoon or spatula, empty the brownie mix into the prepared tin, and smooth out with a spoon for an even bake. 
  8. Bake. Bake uncovered for 35-40 minutes. If using a larger tin, the mixture will be spread out more and this will take a shorter time. If using a smaller tin, the bake will take longer as the mixture will be thicker.
  9. Serving. Once baked, leave to cool in the tin. Remove and cut up to desired size of brownies. For example, 12 squares for the 13x10-inch tin.
