    Ingredients

    • 2 cups | 250 g all-purpose flour
    • 2 tsp | 2 tsp baking powder
    • 1/2 tsp | 1/2 tsp baking soda
    • 1/4 cup | 30 g unsweetened cocoa powder
    • 3/4 cup | 150 g sugar
    • 1 packet vanilla sugar
    • 2 eggs
    • 7 tbsp | 100 ml neutral vegetable oil
    • 1 cup | 250 ml buttermilk or plain yogurt
    • 3.5 oz | 100 g dark chocolate, chopped or in chips

    Step-by-Step Recipe

    1. Preheat the oven to 356°F | 180°C. Line an 8×8 inch | 20×20 cm square pan with parchment, leaving overhang for easy lifting.
    2. In a large bowl, whisk together the flour, baking powder, baking soda, cocoa powder, sugar, and vanilla sugar.
    3. In another bowl, lightly beat the eggs, then add the oil and buttermilk (or yogurt), mixing until smooth.
    4. Pour the wet ingredients into the dry ingredients and gently fold with a spatula just until combined. Do not overmix if you want the brownies to stay tender.
    5. Add the chopped dark chocolate and briefly fold again.
    6. Transfer the batter to the prepared pan and smooth the surface.
    7. Bake for 20-25 minutes, until a toothpick comes out with a few moist crumbs.
    8. Leave in the pan for 10 minutes, then lift out using the parchment and cool completely on a wire rack. Cut into 12 squares.

    FAQ

    What can I use instead of buttermilk if I don’t have any?

    Use plain yogurt or kefir in the same amount. Or mix 1 cup | 250 ml milk with 1 tbsp lemon juice and let stand for 10 minutes until slightly thickened.

    Can I make them without eggs?

    Yes, replace 2 eggs with 4 1/4 oz | 120 g unsweetened applesauce or with 2 tbsp ground flaxseed mixed with 6 tbsp water, then let it sit for 10 minutes to thicken. The texture will be a little more moist.

    How can I make them even more chocolatey?

    Add 1 tsp instant espresso to the dry ingredients, or drizzle the cooled brownies with a thin layer of chocolate ganache. You can also increase the chocolate chips to 5.3 oz | 150 g.

    Tips and Variations

    • Pan and baking time: in an 8×8 inch | 20×20 cm pan, the thickness is ideal. If you use a larger pan, check for doneness sooner.
    • Doneness test: do not overbake. The toothpick should come out with a few moist crumbs so the crumb stays tender.
    • Muffins instead of brownies: divide the batter among 12 paper liners and bake for 18-20 minutes at 356°F | 180°C.
    • Add-ins: nuts (walnuts, hazelnuts), dried cherries, or orange zest all pair beautifully with chocolate.
    • Storage: keep in an airtight container at room temperature for up to 3 days, or freeze in portions for up to 2 months.
