Secret Recipe Club
Time for another Secret Recipe Club post! I can’t believe this post marks one year with the club. In the Secret Recipe Club, each blogger is assigned a different blog each month.
They secretly choose a recipe, prepare it, and post it on a designated day. It is so much fun on reveal day to see what recipes everyone has chosen!
This month I was excited to find out I was assigned Sew You Think You Can Cook! Lauren is a close friend and this has been quite a busy summer for our families.
She recently had a baby and in the past couple of weeks, we have both left Florida for different areas of the country. I am so glad I got a chance to meet baby Wesley before our moves.
I have already made some amazing recipes from her blog: Rolled Pancakes, Brown Sugar Tomato Pasta, Chorizo Mac and Cheese, and Honey Lime Chicken Enchiladas.
These have also been saved for later: Blender Salsa, Cookies and Creme Milkshake, and Strawberry Balsamic Pizza.
Chocolate Hazelnut Coffee Cake

When trying to decide on a recipe, I was a little limited due to first trimester food aversions and currently being in transit with our move.
I am borrowing my parents’ kitchen, so I wanted to make something fairly simple.
This Chocolate Hazelnut Coffee Cake was perfect. I pinned it a few months ago and am glad I finally got the opportunity to try it.
A thick, yogurt-based batter is arranged in a pan with a layer of chocolate hazelnut spread, then covered with a cinnamon chocolate streusel and baked until puffed and golden.
Allow to rest for a few minutes before slicing and serving with coffee or tea.

A Few Tips
Lauren suggested using a 9×9 inch (23×23 centimeter) pan for the cake. I used an 8×8 inch (20×20 centimeter), but agree that 9×9 would work well for less mess. The cake came out quite high and the edges of the streusel overflowed a bit.
If using an 8×8 inch (20×20 centimeter) baking dish, place it on a baking sheet in the oven to catch any crumbs.
The exact cooking time may differ based on the size of the pan.
Use all of the topping. It will spread a bit as the coffee cake rises in the oven.
When I need to work with chocolate hazelnut spread, I often microwave it for about 20 seconds to make it more runny and easier to spread without pressing down into the batter.
I followed Lauren’s lead and used plain whole milk yogurt, but you can also substitute with sour cream.
Cook the Chocolate Hazelnut Coffee Cake until fully set. This will take around 1 hour to 1 hour 15 minutes.

Microwaving the Nutella – why didn’t I think of that!? But then again, I don’t use the ingredient as much as you do! 😉
I’m glad you all liked the cake – and glad you could stomach it! I’m so excited for you guys and baby #2 and hate that I’m now too far away to meet him/her (I guess him!) in the hospital next spring.
Thanks, Tara. Love you and miss you. <3

I had never actually made coffee cake until I tried a cinnamon walnut version for an SRC assignment a few months back. It was such a hit, I’ve been meaning to try another one ever since. As I’m a big Nutella fan, this looks like it might be the one 🙂 Great pick.

All of those recipes sound delicious but I love the Nutella coffee cake. What is not to love? Great SRC pick!

Coffee, Pecan & Nutella swirl coffee cake with crunchy topping, how gorgeous will this be….
Pecan’s will go well I think with this delight, who can possibly add more to perfection, not me!
I hope that I can master it as lovely as you have, I do like the added height, more cake to a slice perhaps!
Yes, it’s great you’ve shared friends recipes, will have a browse through.
On a more savory note, I do like the sound of your curried noodles, they’ll be ideal for a different meal….
Thanks for sharing Tara & all the best with your pregnancy….Good Luck! It will be exciting to see pics of your new arrival, with all my best wishes & love to you & your family,
