My mom’s slow cooker chocolate cake is a straightforward recipe that’s a great way to introduce little ones to cooking. I measured out all of the ingredients, and then had my daughter do all the mixing. Serve Slow Cooker Chicken Tacos with this cake for dessert, and there you have it: an easy, kid-friendly menu. Note: You’ll need a medium-sized, 3.5-quart, slow cooker for this recipe. If you use a large, 7-quart, slow cooker the edges tend to burn.
