Ingredients
- 1 cup Gluten Free Oat Flour (or regular oat flour)
- 2 tablespoons coconut sugar (or sugar of choice)
- 1/3 cup extra virgin olive oil
- 1 tablespoon unsweetened almond milk (or milk of choice)
- 1 teaspoon lime juice
- 1/4 teaspoon sea salt
- 2 avocados (ripe, pitted)
- 1 cup Greek yogurt (low fat)
- 1/4 cup lime juice
- 1/8 cup honey
- 2 tablespoons lime juice for zesting
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Prepare an 8-inch by 8-inch baking pan by lining it with parchment paper or greasing it liberally.
- Step 2: In a standing mixer or with a hand mixer, blend together the olive oil, coconut sugar, almond milk, 1 teaspoon lime juice, and sea salt until combined.
- Step 3: Gradually add the oat flour to the liquid mixture and mix until the dough forms. It will be crumbly but pressable.
- Step 4: Transfer the dough to the prepared baking pan and firmly press it into an even layer using your fingers.
- Step 5: Bake the crust for 15 minutes or until it turns golden brown. Remove from oven and allow it to cool for 20 minutes.
- Step 6: While the crust is cooling, prepare the filling by blending ripe avocados, Greek yogurt, 1/4 cup lime juice, and honey together until smooth and well combined. Adjust sweetness as desired.
- Step 7: Spread the filling evenly over the cooled crust layer.
- Step 8: Place the pan in the freezer for about 2 hours to set the bars firmly.
- Step 9: Remove from freezer, sprinkle with 2 tablespoons lime zest, then slice into 12 bars and serve chilled.
Tips & Variations

- Try adding a handful of chopped fresh mint to the filling for a fresh twist.
Storage
Store these bars in an airtight container in the freezer for up to one week. To serve, let them thaw for about 5-10 minutes at room temperature for easier slicing. Avoid leaving them at room temperature for too long to maintain firmness.

FAQs
Can I use regular flour instead of oat flour?

- 1/4 cup lime juice
- 1/8 cup honey
- 2 tablespoons lime juice for zesting
Instructions
- Preheat and Prepare: Preheat the oven to 350°F (175°C) and prepare an 8-inch by 8-inch baking pan by lining it with parchment paper or greasing it generously to prevent sticking.
- Make the Crust Dough: In a standing mixer or with a hand mixer, blend the extra virgin olive oil, coconut sugar, unsweetened almond milk, lime juice, and sea salt until combined. Gradually add the gluten-free oat flour and mix until a crumbly dough forms.
- Press the Crust: Transfer the crumbly dough into the prepared baking pan. Using your fingers, press the dough firmly and evenly into the bottom of the pan to form a solid crust layer.
- Bake the Crust: Place the pan in the preheated oven and bake for 15 minutes or until the crust turns golden brown. Remove from the oven and allow it to cool for about 20 minutes.
- Prepare the Filling: While the crust cools, combine the ripe, pitted avocados, low-fat Greek yogurt, 1/4 cup lime juice, and honey in a bowl. Mix thoroughly until smooth and creamy. Adjust sweetness if needed according to taste.
- Assemble the Bars: Spread the creamy avocado-lime filling evenly over the cooled crust layer.
- Set the Bars: Place the pan in the freezer for 2 hours to allow the bars to firm up and set properly.
- Finish and Serve: After freezing, remove the bars from the freezer, sprinkle with lime zest, and slice into 12 even bars. Serve chilled for the best flavor and texture.
Notes
- You can substitute coconut sugar with regular sugar or another sweetener of your choice based on dietary preferences.
- If you want a more tart flavor, you can increase the lime juice slightly in the filling, but adjust honey to balance sweetness.
- Ensure avocados are ripe for a creamy texture without lumps.
- These bars are best served chilled and stored in the freezer or refrigerator to maintain firmness.
- Adjust the milk quantity if the dough is too dry or crumbly, adding a bit more almond milk as needed.
