    A super simple recipe for Brownie Blondies! This delicious combo is the ultimate sweet treat and perfect if you can't decide whether to have a brownie or a blondie.

    We love this recipe; it takes a little longer than traditional brownie and blondie recipes, but patience pays off. The brownie batter is made first, followed by the blondie batter, and then swirled together in the baking tin. The result is this fabulous marble-topped creation.

    What is a Brownie Blondie?

    A Brownie Blondie is equal parts of brownie batter mixed with blondie batter. Brownie batter is soft and gooey, and Blondie batter is cakier.

    Why We Love This Recipe

    • Sweet, sinful, indulgent.
    • Soft and fudgy with a crinkle top.
    • It looks so cute!

    Ingredient Notes

    Note: The full quantities are shown in the recipe card below.

    Unsalted butter - unsalted butter gives you complete control of the overall flavour of your recipe, as the salt content in different butter brands can vary a lot.
    White sugar - also known as granulated sugar.
    Brown sugar - adds a lovely rich caramel flavour.
    Cocoa powder - use good-quality cocoa powder. Either Dutch-processed for a deep, smooth flavour or unsweetened cocoa powder if that's what you have available.
    Eggs - use large eggs if possible.
    Plain flour - also known as all-purpose flour.
    Vanilla extract - use vanilla extract or pure vanilla bean paste. Avoid using vanilla essence, as it's less intense.
    Baking powder - also known as baking soda.

    Step by Step Directions

    Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.

    1. Start by making the brownie batter. If you use large eggs, the consistency will be quite runny (which is better for swirling).

    2. Pour the brownie batter into the prepared baking tin.

    3. Make the blondie batter - it's a little thicker than the brownie batter.

    6. Bake in the oven for 35-45 minutes until a toothpick inserted into the middle comes out clean. Leave the brownie blondie to cool in the tin for 30 minutes before slicing it into 16 squares.

    Serving Suggestions and Variations

    We love our Brownie Blondies served with vanilla ice cream for dessert or just plain and simple for afternoon tea.

    For variations to the recipe, you could always add chocolate chips or walnuts to the batter before baking.
