World's Best Chocolate Oat Hot Fudge Cake with that gooey bottom (sometimes called chocolate pudding cake)

Every spring lemon, berry and cupcakes start filling the internet and I’ll be honest with you. I’m totally a fan. Especially of the lemon and berry desserts. Is there really any better combination? Well, maybe chocolate and berries, especially raspberries. I wanted to mix things up a little bit this spring so I started experimenting with chocolate and Quaker Oats Steel Cut Quick 3-Minute Oats . I know, not where you thought I was taking this right, but working with Quaker totally sparked a flame in me for a world’s best chocolate oat hot fudge cake and I just had to test it out.

You see, I don’t think that chocolate needs to disappear when the weather starts warming up. In fact, Cade votes for chocolate all year round and who can really argue with that? I love an old fashioned oatmeal cake but I wanted to make an apple version (don’t worry, it’s coming I just have to work on the recipe more) and immediately Cade said, but doesn’t chocolate sound more fun?

Quaker Quick Steel Cut Oats

Oh gosh, of course it sounds fun! I’m such a fruit addict though, I could not help but toss a few sweet raspberries in with everything and you know what? It was way better than normal! I’ve had issues with steel cut oats for a while. I love them. They fill me up more than other breakfasts and in a good way, but they take forever to make! I was so thrilled to find out Quaker has quick steel cut oats now made from 100% whole grains that are expertly cut to preserve texture. Plus, they’ve got individual servings in different flavors. Booyah!

How to make a hot fudge cake

Don’t be afraid of this recipe and the part about sprinkling the cocoa on top and pouring hot water on that. I promise it’s normal and what will make that pudding bottom.

And those steel cut oats? Don’t worry they cook up into little bits that everyone was convinced were pieces of toffee! HA! I love that! But do not get fooled, this is not your normal cake, but more like a pudding cake with a fudge bottom so don’t overbake it.

Our girls had so much fun making this recipe. They were so worried about those steel cut oats at first, but as you can see, the moment I finished photographing and started cleaning up I had a little one sneak over and start devouring the whole thing. And just like any good mom I had to capture the moment because heaven knows these kids are growing up way too fast.

Are Oats Gluten Free?

Non-contaminated, pure oats are gluten-free.

Contamination can occur when oats are processed in a facility that also processes wheat products.

Always read the label to be safe.

Is Oatmeal Good For You?

Oats are some of the healthiest grains on earth.

They’re a gluten-free whole grain and a great source of important vitamins, minerals, fiber and antioxidants.

Oats and oatmeal have many health benefits.

Oats can help with weight loss, lower blood sugar levels and a reduced risk of heart disease.

What Can Be Substituted For Buttermilk?

For each cup of buttermilk, you can use 1 tablespoon of white vinegar or lemon juice plus enough milk to measure 1 cup.
