But the magic doesn’t stop there – it isn’t just drizzled with any old hot fudge, it’s topped with peanut butter hot fudge you’ll be tempted to drink for breakfast. Dessert just got taken to a whole new level.

Recipe FAQs

What is the best chocolate to use for homemade brownies?

I use the Ghirardelli’s 100% cocoa bars found in the baking aisle for the unsweetened chocolate. Man, it’s good!

Does hot fudge need to be refrigerated?

Make sure that your hot fudge is completely cooled before putting it in an airtight container and placing in the refrigerator. The hot fudge will last up to 2 weeks. Simply reheat when you are ready to use the hot fudge again.

How long should I let brownies cool before cutting them?

I know that it is so tempting to jump into freshly baked brownies, but if you want a really crisp, clean cut line you need to wait until the brownies are completely cooled. This typically takes about 30 minutes and an abundance of self control.

Expert Tips

  • Don’t overbake the brownies so they stay nice and fudgy.
  • If you need to keep the sauce warm for a while (for a party or other get together), put it in a crockpot set to warm for up to 4 hours.
  • A dollop of whipped cream is always a fun touch on top of a sundae.
  • This showstopper sundae would be a delicious dessert for Sunday dinner or to celebrate a special occasion. It has all of the classic sundae vibes with the yummiest peanut butter twist.
  • In order to cut down on the preparation time, I like to bake the brownies and make the hot fudge ahead of time. Then it only takes a few minutes to assemble the sundae and you are ready to dive in.

Notes
