Cinnamon Coffee Cake

Does it seem like holiday parties are happening earlier this year? I went to one on Tuesday and today I have our departmental party. Since there are so many holiday parties going on now and with each holiday desserts like peppermint chocolate roll cakes or vanilla pomegranate oatmeal cookies. I am sharing with you something different you can bring along to your next holiday gathering. This cinnamon coffee cake will be perfect to add to a dessert table filled with peppermint and cranberries.

I actually made this coffee cake for the first time two months ago, and it has quickly become a favorite snack cake around here. My husband loved how different it was with the M&Ms and I loved how easy it is to put together. The cake itself is light and fluffy, lightly spiced with cinnamon. As if that is not enough, this delicious cake is topped with a crunchy crumb layer made with toasted hazelnuts and crunchy M&Ms.

Now I know the M&Ms addition sounds strange in a cinnamon cake but trust me it works. It’s the slightest addition of chocolate that brings a true flavor kick. Although you could also just do chocolate chips if you’d like or skip the M&Ms all together. You will still be left with a crazy good cinnamon coffee cake you will love. 

I don’t think any of my weekend brunches will be complete without this cinnamon coffee cake in my future. Make this holiday season special by baking something different to bring to your holiday gatherings. I will definitely enjoy a slice (or two) of this snack cake as I tackle the end of this busy week, before hitting the holiday party!! I hope you have a great weekend.
