150gketo-friendly sweetener of choiceerythritol works well
90gmelted unsalted butter
4tbspextra virgin olive oil
⅓tspbaking soda
⅓tspsalt
a few tbsp of cold waterif necessary
Instructions
In a large bowl, mix all the dry ingredients. Add both the olive oil and the melted butter and, while mixing, you'll notice that the ingredients start to form a sort of crumble. Add the eggs (whisked) and adjust the consistency o the batter with a few tablespoons of water, if necessary.
Using a spatula, spread the batter into a 20x20 cm baking pan (lined with parchment paper or well-coated with olive oil). Bake in a preheated oven at 180°C for approx. 20 minutes for a fudgier consistency or 30 minutes for cakey brownies. Allow the brownies to cool completely before cutting them.
Notes
For extra fudgy brownies, you can add some pieces of a 100% cocoa chocolate bar (approx. 20-30 g) melted in a Bain Marie. Since this chocolate is unsweetened, you may want to slightly increase the amount of sweetener in the batter.
Add a few tablespoons of cold water to adjust the consistency of your batter. The final result should be a thick batter that you have to spread in the baking pan using a spatula; it's not a smooth batter like the one you usually make for cakes.
Using this recipe and a 20x20 cm baking pan, you'll be able to make 6 large brownies but you could also decide to cut them into smaller pieces.
