Tips to Make Fudgy S’mores Brownies
- For best results, use high-quality chocolate chips and cocoa powder to enhance the flavor.
- Ensure you don’t overmix the brownie batter; folding just until combined will yield the fudgiest texture.
- If you want a more intense s’mores flavor, consider using flavored marshmallows or adding a layer of chocolate ganache on top.
Variation
You can customize these brownies by adding different flavor extracts, such as almond or hazelnut, or experimenting with different types of chocolate, such as milk chocolate or white chocolate. For a nutty twist, add in crushed nuts or a swirl of nut butter before baking.
FAQs
Can I make these brownies ahead of time?
Yes! These brownies can be made a day or two in advance. Store them in an airtight container and they will still taste delicious.
Can I use a different type of cracker?
Absolutely! While graham crackers are traditional, you can use any cookie or cracker of your choice, such as chocolate wafer cookies for a richer flavor.
What if I don’t have a candy thermometer?
You can test the sugar mixture by dropping a small amount into cold water; it should form a soft ball when ready. Alternatively, using a digital thermometer can help ensure accurate results.
