Step 1

Preheat oven to 375°F. Grease and flour a large bundt pan and set aside. In a stand mixer fitted with a paddle attachment beat the butter and sugar together until light and fluffy. Scrape down the bowl and add in the yogurt, vanilla, and eggs, and mix well.

Step 2

In a separate bowl mix together the flour, baking soda, and salt. Add the dry ingredients to the wet ingredients and mix until combined and no clumps of flour remain. Using a rubber spatula, fold in the chocolate chips.

Step 3

Meanwhile, using a fork, whisk together brown sugar and cinnamon for the cinnamon swirl. Pour half of the batter into the bundt pan and smooth using the back of a spoon. Sprinkle half of the brown sugar mixture over the batter and swirl into batter using a fork or knife. Pour in the second half of the batter and swirl the rest of the brown sugar mixture over it.

Step 4

Bake for 25-30 minutes, or until a knife comes out clean when inserted into the cake. Allow to cool for 10 minutes, then plate and serve for breakfast, lunch, and dinner.
