To make use of the gorgeous produce we have readily available right now, I decided to make something I hadn’t really even liked in my carb-addicted dark past. Lemon bars had never really appealed to me, probably because they don’t involve chocolate. And yet they just sounded really good the other day for some reason, with their refreshing tartness and shortbread crust. The recipe is well-suited to a healthful makeover because of the low carb content of eggs and lemons, so I just couldn’t resist trying a batch. After demolishing a trial batch along with my faithful testers, it’s safe to say these gluten-free low carb lemon bars are just as church picnic worthy as their high carb counterparts!
As far as the technical baking stuff goes, you do need erythritol if you want to add bulk and lessen the carb count per bar, not to mention the nice rounded sweetness from combining it with the stevia. It also adds a nice crunchiness when it crystallizes, but no overwhelming cooling effect. However, if you refrigerate these bars, you’ll want to pop ’em in the microwave for 10 seconds or so to warm them up for the best mouth feel. Furthermore, you can use a product like ThickenThin Not Sugar (or pure acacia gum) to lessen the amount of recrystallization if you want a smoother texture. You can forgo the erythritol altogether, but you’ll have to use a lot of stevia or just accept a less sweet finished product. Finally, the xanthan gum takes the place of flour in the original recipe to firm up the top of the bars. You could probably use a bit of coconut flour for a similar effect.
Health-wise, these bars are a delicious vehicle for the goodness of raspberries and lemons, which are bursting with vitamin C and cancer-fighting compounds. In lemon, the limonins have the free radical scavenging cytotoxic effects. In red raspberries, ellagitannins may block carcinogens and ward off sickness. Both raspberries and lemons are low in carbs, which makes them perfect candidates for a after-dinner treat or a pre-workout snack. I sip at stevia-sweetened lemonade all day, which is supposed to aid in the absorption of the catechins (antioxidants) in my green tea. I’ll drink to that!
Healthy Raspberry Lemon Swirl Bars
Makes eight bars
1/4 cup butter
For ALL NATURAL sugar-free sweetening:
-1 tablespoon erythritol or xylitol
-1/4 teaspoon pure stevia extract
Pinch sea salt
1/2 cup plus two tablespoons almond meal
1/4 cup oat or buckwheat flour (oat flour is a lot prettier!)
1/4 teaspoon xanthan or guar gum
2 large cage-free organic eggs
1/2 cup erythritol
1/8 teaspoon pure stevia extract (NuNaturals brand)
1/4 cup organic lemon juice
2 teaspoons lemon zest
Pinch sea salt
1/4 teaspoon xanthan gum
1/2 cup organic raspberries
1 teaspoon organic lemon juice
1 teaspoon erythritol
Fresh raspberries for garnish
Soften butter for shortbread. Powder erythritol in coffee grinder or blender. Cream butter and erythritol together, then work in flours and gums with a fork until thoroughly combined. Add a pinch of salt and stevia. You want it to be a bit sweeter from the stevia than you can stand it, because some of the stevia’s sweetness breaks down under heat. Press or spread into an 8″ by 4″ loaf pan lined with buttered parchment. Bake at 350 degrees until lightly browned, 15-20 minutes. Let crust cool while you prepare the filling. Stick it in the freezer to speed the process.
Powder erythritol. Beat erythritol with eggs, lemon juice, and zest. Add gums. Add a pinch of sea salt and stevia to taste. Pour over shortbread crust.
Puree raspberries with lemon juice and erythritol. Strain through a mesh colander, pushing the puree through with a spatula, if you don’t want seeds in your bars. Drop raspberry puree onto lemon filling in different spots and swirl with the spatula. Dot batter with fresh raspberries if desired. Bake for 20 minutes or until just set. I left the center of mine slightly jiggly, and it firmed up after cooling.
