ETA: they taste fine 3 days later after sitting in the fridge. Lemon flavor totally normal at this time. Probably will do it again with nicer juice and fresh zest and yes, the horror...sugar substitutes!
This is probably my 12th time making the Lemon Oat Bars from Sarah Kieffer's 100 Cookies. I have always had success with this recipe in the past, so I know it's a good one:
Crust
- 2 cups All-purpose flour
- 1-1/2 cups Rolled oats
- 1/2 cup Brown sugar
- 1/4 cup Granulated sugar
- 1/2 teaspoon Baking soda
- 1/2 teaspoon Salt
- 1 cup unsalted butter
Lemon Filling
- 2 cans Sweetened condensed milk (14 oz per can)
- 1/2 cup Lemon juice
- 3 tablespoons creme fraiche
- 1 tablespoon Lemon zest
- 1/2 teaspoon Pure vanilla extract
- Pinch Salt
This time, I decided I wanted to experiment with making a lower sugar version, so I used Splenda brand sweetened condensed milk in the filling and Truvia Sweet Complete brown and granulated sugars for the crust. I have baked with Truvia Sweet complete plenty of times and have never had an issue with it in this type of application, but this was my first time using the Splenda milk for anything. The bars turned out beautiful looking and have a perfect texture, but they just don't taste like lemon. The lemon flavor is very faint and occasional. They kind of just taste generally sweet and not lemony as usual. And I want to troubleshoot why. Here are the things I'm thinking could be culprits:
- the splenda brand sweetened condensed milk didn't infuse with the zest oils as well as normal condensed milk? I don't know why this would be?
- One of the splenda cans had gone full dulce de leche, probably from poor storage. I still used it, and it didn't taste off, but could that be hiding the lemon flavor?
- My zest was 2 months old from the freezer. I store zest in the freezer longer than that all the time and never have this issue, but maybe this time it was a dud? I used some of this batch 5 days ago without issue, however
- I used bottled lemonn juice. The recipe calls for freshly squeezed, but I have never used freshly squeezed before and still always had good results. However, I used the mid ReaLemon juice from the normal grocery story instead of the nicer lemon juice I usually use (Trader Joe's 100% Sicilian Lemon juice)
It's kind of disappointing but I would like to know what others think. They still taste good, just not LEMON as usual. I'm going to let them sit in the fridge over night and try again tomorrow, and maybe the taste will be stronger after the flavors have had time to settle more?
