The Sassy Pair

I don’t have a ton of experience with vegan baking, but I’m trying to experiment more! Veganism is such a healthy lifestyle, and with so many people practicing it, its good to have vegan options for parties and events. These key lime bars are more exciting than classic vegan brownies, and they have some awesome ingredients for your body.

This recipe is very simple, and only uses a food processor for equipment. If your crust isn’t coming together well enough to press into the dish, you can add a bit more coconut oil or maple syrup. I had to take mine out and remix it to get the desired thickness. As for the filling, make sure you taste it! Ideally you want to taste mostly lime, and not avocado, so adjust the amount of lime juice to taste. It’s also important to keep the bars refrigerated so that they don’t drip and make a huge mess.

Common Vegan Baking Substitutes

It can be tricky to transform your favorite dessert recipe into a vegan one, but if you are experimenting, here are a few classic swaps. Just remember: vegan means no animal products at all (meat, seafood dairy, eggs, and even honey).

  1. Swap cow’s milk for almond milk, coconut milk or rice milk. In place of heavy cream, try full fat coconut milk or soy creamers.
  2. Instead of eggs, use applesauce, a mashed banana or water with baking soda. (egg replacement exists but can be expensive!)
  3. Exchange the dairy butter for coconut oil + water. Basic conversion is for 1 cup dairy butter, use 3/4 cup coconut oil mixed with 1/4 cup water

To give these bars a little more pizazz and flavor, I whipped up some coconut cream to spread on top. This is optional, but I highly recommend it! You can find the easy coconut whipped cream instructions in my previous peach galette recipe. The only ingredients you’ll need is a can of full fat coconut cream and a little bit of powdered sugar.


  • Crust
  • 1 c old-fashioned oats
  • 1/3 c unsweetened coconut flakes
  • 1/4 c sliced almonds
  • 1/4 c pure maple syrup (or honey depending on restrictions)
  • 4 Tbsp coconut oil (melted)
  • 2 Tbsp key lime juice

  • Filling
  • 2 ripe avocados (pitted)
  • 3 Tbsp coconut oil, melted
  • 3 Tbsp pure maple syrup (or honey depending on restrictions)
  • 1/2 c lime juice (or more to taste)
  • Zest of 1 lime


  • Line an 8×8 baking pan with parchment paper or foil.
  • In a food processor, pulse oats, coconut flakes, and almonds until finely chopped.
  • Add maple syrup, coconut oil, and key lime juice. Continue to pulse until mixture pulls together into a ball.
  • Press mixture into prepared pan.
  • Wash food processor.
  • Blend all the filling ingredients until smooth and pour over crust.
  • Freeze for two hours then move to fridge for an additional 30 minutes before cutting and serving.


These bars will be slightly messy when cut, and it’s best to serve cold to avoid dripping.
Store covered in the refrigerator for about 3-5 days.
