What Makes This Recipe Great

I am a sucker for a good dessert bar! Give me anything that involves peanut butter and chocolate, and I am IN! These Vegan Millionaire Shortbread cookie bars remind me of a healthier vegan Twix bar or a homemade peanut butter tasty cake– Yum!

Millionaire Shortbread is typically made with a shortbread layer topped with caramel and then a final layer of chocolate. For this healthier gluten-free shortbread recipe, we use a simple grain-free shortbread crust, 3-ingredient vegan peanut butter caramel, and a dairy-free chocolate ganache. The layers all harden together to form the tastiest, decadent bar you will ever have! These little vegan millionaire shortbread bites of heaven are a must-make!

Ingredients for vegan cookie crust: Almond flour, coconut flour, vanilla, coconut oil, and maple syrup

Ingredient Notes

Almond flour: Look for fine, blanched almond flour for the gluten-free shortbread.

Coconut flour: I like Bob’s Red Mill, but you can use your favorite.

Maple syrup: This should be 100% pure maple syrup.

Coconut Oil: Refined or unrefined will work for this recipe. You always want to measure it once it is melted

Nut Butter: I have made this with both peanut butter and almond butter, and both work beautifully. I used Justin’s brand, and the consistency worked well. You want to look for nut butter that is smooth, yet not too runny.

Chocolate Chips: I like Enjoy Life Dark Chocolate Chips, or to keep this paleo, look for Hu Kitchen or Eating Evolved brand.

Coconut Milk: You’re going to want to look for full-fat canned coconut milk, and only use the hardened white part when measuring. I like Native Forest or Thai Kitchen brands.

Recipe Step by Step

Steps to make gluten-free cookie crust

  1. Make the Gluten-Free Shortbread: First, preheat your oven to 350 and spray an 8×8 pan with cooking oil. Add the gluten-free shortbread crust ingredients (almond flour, coconut flour, maple syrup, melted coconut oil, vanilla, and sea salt) to a bowl and mix well. Transfer the mixture to the pan and press down using your fingers. Make sure to cover the bottom of the pan. Poke a few holes in the crust, then bake for 16-17 minutes.
  2. Make the Vegan Peanut Butter Caramel: Combine the ingredients in a bowl and whisk well for 2 minutes. The longer you whisk, the more it will look like a caramel consistency.
  3. Layer the Caramel: Add the caramel on top of the baked shortbread crust and spread it out evenly. Pop the pan into the freezer for at least 30 minutes.
  4. Make the Dairy-Free Chocolate Ganache: Combine the chocolate chips and coconut milk in a dish and microwave to melt, stirring in 30-second increments until smooth.
  5. Layer the Chocolate: When the pan is ready to be taken out of the freezer, spread the ganache on top and sprinkle with sea salt (if desired). Refrigerate for another 30 minutes (minimum).
  6. Serve: Slice into 16 gluten-free shortbread cookie bars and enjoy!

FAQs

Can these gluten-free shortbread bars be made nut-free?

Unfortunately, I have only tested these using both almond butter and nut butter. If you try to make them nut-free, please share what you used and how it went in the comments below!

Is this vegan millionaire shortbread recipe paleo?

It can be! Simply swap the peanut butter out for almond butter and make sure to use refined sugar-free chocolate chips.

Are these bars egg-free?

Yes, they sure are!

Are these vegan millionaire shortbread bars healthy?

Typically, not so much. However, these bars are a bit healthier since they use grain-free flours like almond and coconut, coconut oil, and coconut milk which both have healthy fats and refined free sugars like maple syrup for sweetening.

Ingredients

Shortbread Crust

Nut Butter Caramel Center

Dairy Free Chocolate Ganache Topping

Equipment

  • 8×8 pan

Instructions
 

  • Preheat your oven to 350 and spray an 8×8 baking pan with cooking oil.
  • Combine all of the gluten-free shortbread crust ingredients in a bowl and mix well until combined. Transfer the dough into the baking pan and press down with your fingertips. Make sure it is spread out evenly to cover the bottom of the pan. Poke a few holes in the crust with a fork. Bake for 16-17 minutes, until slightly golden brown.
  • Meanwhile, make the caramel. Combine the melted coconut oil, nut butter of choice, and maple syrup in a bowl and whisk vigorously for 2 minutes. It should resemble caramel after mixing well. Pour the caramel over the crust and use a spatula to spread it out evenly. Place the pan into the freezer for at least 30 minutes.
  • Next, make the chocolate ganache. Melt the chocolate chips and full-fat coconut milk in a bowl in the microwave, stirring every 30 seconds until smooth. Alternatively, you can heat both of them over a double boiler on the stove and stir until smooth.
  • Once the caramel layer has hardened in the freezer, spread the chocolate ganache out evenly on top. Sprinkle flaky sea salt on top, if desired. Place the pan back into the freezer for another 30 minutes (minimum).
  • Slice into 16 gluten-free shortbread squares, and enjoy!
