After that, add in your vanilla, eggs, and Greek yogurt, and again, mix well. Pretty standard operating procedure here, folks. Meanwhile, in a separate bowl, put your dry ingredients in together, and whisk, so that they are well incorporated.
Your wet ingredients may look a little lumpy, but that's okay! With your mixer running on low, slowly add in your dry ingredients. Otherwise, you will be wearing more of the flour mix than goes in the bowl!
Once its all mixed, add about 1/2 C of mini chocolate chips, and let these mix in for a few seconds before turning your mixer off. You want these to just mix in!
Once you have enough hearts lined up, take them out and set them aside. Take about 1/3 of the cake batter, and smooth it out into a level layer. Take your line of hearts (or, whatever shape you're using) and gently press them into the batter, again, making sure that the first shape is about 1/4" away from the edge of the pan, and that the last heart is about 1/4" away from the other end of the pan.
So, with that in mind, run some batter on either side of the hearts, then over the top, smoothing over the top. Once your batter is all smooth and pretty, feel free to sprinkle with another 1/2 C or so of the mini chocolate chips. I always do! Who ever complained that something was too chocolaty?! You don't need that kind of negativity in your life, that's for sure. Once you're ready, pop this beauty into the preheated oven, and bake for 40-50 minutes, or until the cake is cooked all of the way through. Let cool for about 15 minutes in the pan, then move to a wire rack.
Slice in front of your audience, and accept all of the, "Ooohhh"s and "Aaahhhh"s with a smile, and don't tell anyone how amazingly easy this was!
I hope you all have a lovely Valentine's Day, and spend it with those that you love! See you next week, everyone!
