This recipe is delicious. However, it seems that the full recipe of graham cracker dough is way too much for the size of tart pan specified (14×4). My tart pan is a Wilton 14×4.5 and the crust was much too thick with the full recipe of dough. I took out quite a bit (I wish I’d weighed it so I’d know for next time) and made crackers from it. I’d love to know if the Bake from Scratch kitchen really used the full recipe of dough. The photos that accompany the recipe certainly don’t look it.
Hey Kevin,
Thank you for reaching out! After talking with our Test Kitchen, they did note that they had some over flow from the original graham cracker recipe that they trimmed off after rolling out and pressing into the tart pan. That being said, they don’t recall having too much excess crust. We hope this resolves your baking issues!
What temperature does the crust bake at?
Heather,
Thanks for reaching out! The crust will bake at 350ºF, which you will find in the Homemade Graham Crackers recipe.
happy baking!
Absolutely love it!
Thank you for answering that the bake temp is 350 as I could not find it anywhere in the recipe in your Artisan Pies & Tarts magazine. Making this recipe this week! Can’t wait to eat it!
I have made this once previously and it was a big hit! Making it again but need it made a day in advance. What is the best way to store overnight? Covered? Uncovered?
Hi Judy! We’re so glad you’ve loved this recipe! To store it overnight, we recommend storing the tart in an airtight container or loosely covered in plastic wrap in the refrigerator.
Any chance of getting this recipe but for a round tart tin? I love the look of this but really have no space for yet another tin.
Hi Lyndsey!
Thank you for reaching out! This recipe will work with a 9 or 10-inch tart pan. Happy baking!
I was wondering if I could use a 9″ springform pan ? I don’t want to but a pan that I won’t use often instead, use an existing pan. Thanks !
Hi Barbara,
Thanks for reaching out! We completely understand. A 9″ should be fine as it has a similar surface area to the 14×4-inch pan. You may want to line the bottom and sides with parchment to assist with removal. Happy baking!
Trying to make this tonight. So far all components have come out great, except my graham cracker dough was very crumbly, I was unable to roll it out. Is there a liquid ingredient missing from the instructions? The 3 tbs of honey/molasses doesn’t seem to be enough to bind it? Or maybe I’m missing something? Thanks!
Hi Stephanie!
Thanks for reaching out! The butter will be the biggest binder here. You may add water, a quarter teaspoon at a time if you feel the dough is too dry to roll. Just be leery about adding too much!
This looks so good! Where can I find the recipes for Chocolate Ganache Filling and
Coconut Pastry Cream? They aren’t below and I didn’t find them in the search. Thanks!
Hi Elsie,
Thank you for bringing this to our attention. The recipes for both Chocolate Ganache Filling and Coconut Pastry Cream have been added. Happy baking!
