Ser-lutty Brownies

print recipe

Let’s talk about my SER-LUTTY BROWNIES! It I want something truly indulgent, completely and utterly over the top and full of every kind of chocolate, this is what I make. OOFT GET IN MY FACE IMMEDIATELY.

Let me describe it a little for you in case you’re still not convinced. This set-lutty brownie creation consists of a chewy chocolate chip cookie layer, a crunchy biscuity Oreo layer and a rich and gooey dark chocolate brownie layer. If that isn’t enough, I like to top it off with lashings of silky white warm chocolate sauce to thoroughly make sure I’ve got every type of chocolate possible on it. I can’t write this without my mouth watering and I’m currently in a public setting so this is actually quite embarrassing.

I’ve also developed an air-fryer friendly recipe so you can have this baked treat of gooey goodness even quicker. Find this recipe and many many more in my book, Poppy Cooks: The Actually Delicious Air Fryer Cookbook. That’s right, I got a sneaky book plug in there hehe.

For another recipe just as rich but with ONLY 6 INGREDIENTS, I recommend trying my chocolate salted caramel tart. You get the same level of indulgence but without the need to buy less 87 types of chocolate.
