Tell me about these rocky road brownies!
- Texture: if you love a fudgy brownie, then this is the recipe for you! These brownies with marshmallow fluff are super soft, chewy and rich. The toasted pecans and mini chocolate chips on top give a great crunch
- Flavour: with a combination of melted chocolate, cocoa powder and chocolate chips, these brownies are mega chocolatey! The pecans balance out the sweetness of the brownie and marshmallow fluff.
- How easy are they: with no mixer required, these marshmallow swirl brownies are super easy! The only slightly tricky part is melting the chocolate over a double boiler, but you could also melt it in the microwave.
- Time: these brownies only take 20 minutes to prep, and 25 minutes in the oven – giving you brownies in under an hour! Definitely let them sit for at least an hour before cutting, as they’re so gooey they’ll need a bit of time to set.
How to make extra fudgy brownies
- Cocoa powder replaces some of the flour, which makes these brownies less cakey and more dense and moist.
- I don’t use any baking powder. Adding baking powder lifts things up and makes it cakier, which is the opposite of what I want!
- I use a combination of butter and oil, the butter gives us all the flavour but the oil gives us that soft texture. I also use a mixture of white sugar and light brown sugar because they both bring something to the table! White sugar is what gives us a crackled top, and light brown sugar brings moisture.
- This recipe uses a lot of eggs! Those extra egg yolks give a lot of structure to the brownie
What substitutes can I make?
- If you’re feeling adventurous, make your own marshmallow fluff! I have a recipe for it here.
- Add mini marshmallows on top! If you do this, add them in the last 5 minutes of baking the brownies.
- Swap out pecans for any other nuts you like
- Substitute the chocolate chips on top for butterscotch chips or peanut butter chips
FAQs and Tips
How do I know when these brownies are done?
A toothpick inserted in the brownies should come out with a few crumbs, and the brownies will finish baking when you take them out of the oven. You don’t want to overbake these!
How do I store these?
These brownies last 5 days in an airtight container, although mine definitely get eaten before that!
What should I do with the extra egg whites I have leftover?
You can freeze egg whites! Freeze them in a clean container and then thaw them for future recipes. You could also use egg whites for your breakfast omelette, keep them to brush the bottom of a pie, or keep them to make your own marshmallow fluff!
