High Altitude Olive Oil Fudge Brownies (Dairy Free)

Heather Smoke
These olive oil brownies are incredibly moist, dense, fudgy, chewy, and deep-dark-chocolatey. Made with oil instead of butter, they are dairy free, but not vegan.

Equipment

Ingredients
 

  • ¾ cup olive oil or vegetable oil (choose an oil with a neutral flavor)
  • 2 cups granulated sugar
  • 4 large eggs
  • 4 tsp vanilla extract
  • 1 cup (6 1/2 oz) semi-sweet chocolate chips, melted (use dairy free chocolate chips if dairy is not tolerated)
  • 1 ⅓ cups unsweetened Dutch processed cocoa powder
  • cup all-purpose flour, fluffed, spooned and leveled
  • 4 tsp instant espresso powder or instant coffee
  • ½ tsp coarse Kosher salt (if using table salt, use half the amount)

Instructions
 

  • Preheat the oven to 325 F, and position a rack in the center of the oven. Line a 9x9 inch baking pan with parchment paper. The paper ensures easy release of the brownies, and helps with cutting them cleanly.
  • Using an electric mixer (stand or hand-held), beat together the oil, sugar, eggs and vanilla for 5 minutes on medium speed until well-aerated. If you don't have a mixer, you can use a whisk and beat the mixture by hand, but this will be pretty tiring.
  • Add the melted chocolate and whisk until smooth. The best way to melt the chocolate is either to use a double boiler, or in the microwave, for about 2 1/2 - 4 minutes on 50% power, stirring until smooth and melted.
  • In a separate bowl, sift together the cocoa powder, flour, espresso powder and salt. Add the dry ingredients to the batter, and use a spatula to stir everything together until combined. Spread the batter into the prepared pan.
  • Bake the brownies for 30 minutes, until the edges and center appear set. Place the pan on a cooling rack and let cool completely before cutting.
  • If you rush cutting the brownies, they'll have the gooey texture of under-cooked brownie batter. You really need to let them cool and set for at least 6 hours, but personally, I like to bake them at night, then let them cool and set up overnight (12 hours) before cutting.
  • To cut the brownies, lift them out of the pan using the paper, and set them on a cutting board. Use a sharp non-serrated knife, wiping the blade clean in between cuts.

Notes

Store leftover brownies in an airtight container at room temperature for up to 3 days, or in the freezer for up to 3-6 months.
With no dairy (butter or milk products) in these brownies, this is a dairy free recipe, but it is not vegan since it contains eggs.  Eggs are not considered a dairy/milk product.  Be sure to check the ingredients on your chocolate chips and use a dairy-free product if dairy is a concern.
