This is called Picnic Cake for many good reasons. It is the perfect cake to take on a picnic because, without frosting, it is easy to transport and it doesn’t have to be kept refrigerated. The richness of the cake makes it great for serving a crowd because you can serve smaller pieces and everyone is still super satisfied! The cake is moist and delicious on its own and the chocolate chip topping adds just the right amount of extra sweetness. Adding oats to the mix is what makes this cake is so rich and dense. I have never put oats in a cake before, but — trust me — it is AMAZING! We got this recipe from my Aunt Cathie, who is an amazing cook! Everything she bakes is so delicious and this recipe definitely does not disappoint. (If you are looking for other tasty treats to bring to a picnic, our Salted Caramel Rice Krispie Treats also came from her recipe book, and they are DIVINE!) If you’re eating this cake at home, or if you bring a cooler on your picnic, this cake is great served with whipped topping or vanilla ice cream.
