Out of the Box Desserts! This book reflects Hayleyโcreative, fun, and full of personality. When we first got our copy, my kids eagerly flipped through the pages and bookmarked nearly every recipe they wanted to try. Only a handful of recipes were left unmarkedโtheyโre determined to make the rest! What I love most about these desserts is how approachable they are. Every recipe is delicious and simple enough for my kids to help. Itโs a mouthwatering collection thatโs as fun to create as it is to eat!
I met Hayley through blogging, and what I grew to love about her is her edge; she is constantly pushing the envelope. She is accurate and lets you in her inner circle with every recipe.

I can’t wait for you to try this Hot Fudge Slow Cooker Brownies recipe. It is so easy, delicious, and, well, it is made with hot fudge, so you know, you can’t get any better than that.
Step to making hot fudge slow cooker brownies
Grease your slow cooker generously with cooking oil. Set aside.
If you make your hot fudge (which I strongly suggest as it only takes 10 minutes and is SO MUCH tastier), prepare hot fudge sauce. Click here for directions.
In a large mixing bowl, add brownie mix, oil, 1/4 cup water, and eggs until well combined. Pour batter into the slow cooker.

Whisk together 12 ounces of hot fudge sauce and 3/4 cup hot water until smooth. Pour over the brownie batter in the slow cooker. Top slow cooker with lid and cook on high for 3 to 3 1/2 hours or until the edges are cooked.

Hayley mentions the center will be gooey, which is how it should be. Trust me, you want the center gooey. It is oh-so good.
Serve immediately, top with ice cream and hot fudge or caramel sauce. Grab a spoon and dig in!

I’m betting that every recipe in this book is amazing but the Mint Cookie Overload Cake is the one I can’t stop thinking about!
I really want to try the Baklava Brownie Bombs. They sound awesome!
Oh this looks so good! I really want to try this one! I have to get her book, I want to try everything!
I’d love to try all of her recipes! But her granmothers coffee cake is calling my name.
I would love to try the Damn Good chocolate cake or anything chocolate! I LOVE chocolate anything! This Hot Fudge brownie looks amazing!
Looks great!
Can this recipe be doubled? If so, does that change the cooking time? I have a 7 quart slow cooker and this sounds great for a crowd..
I have never doubled this recipe and not sure how it would turn out. If you try it I would say yes, you would need to increase the time but not sure you would double it. San
