This Chocolate Chip Coffee Cake is soft and tender, and it's topped with an amazing brown sugar + cinnamon streusel. Oh, and it's packed with chocolate chips, too!
Using a medium bowl, add sugars, cinnamon, ginger and salt; stir until well combined.
Add the melted butter; stir until well combined.
Add the flour, chocolate chips and walnuts; stir until well combined. Set mixture aside.
For the Coffee Cake
Preheat oven to 350°F.
Grease and flour (or spray with nonstick cooking spray) a 9”x3” round cake pan. Set pan aside. (See note below.)
Using a medium bowl, add the flour, baking powder, baking soda and salt; stir until well combined. Set mixture aside.
Using a stand mixer fitted with the paddle attachment, cream together the sugar, brown sugar and butter until light and fluffy (~2-3 minutes on medium speed).
Add eggs, one at a time, mixing after each addition.
Add vanilla, lemon juice and sour cream; mix on low speed until well combined.
Add dry ingredients (from above) to the bowl; mix on low until just combined.
Add chocolate chips and {optional} walnuts; mix on low speed until just combined.
Transfer batter into prepared 9”x3” pan.
Crumble streusel on top of batter.
Bake at 350°F for 45 minutes.
Tent the top of the cake with a piece of tin foil to prevent the streusel from burning. Continue baking for another 40-50 minutes, or until a toothpick inserted into cake comes out mostly clean.
Place cake on a wire rack for at least 30 minutes before slicing.
Notes
It’s important to use a deep cake pan for this cake. (I actually used a 9”x3” springform pan.) If you don’t have a deep pan, then you can split the batter into two smaller pans and reduce the overall baking time.
