Ingredients & Substitutions

Here is everything you need to make the best homemade twix bar recipe:

Almond Flour: You will want to use blanched almond flour. You can also use these gluten-free flour subtitutions.

Vanilla Protein Powder: Use collagen powder with callogen peptides, whey protein powder, a plant-based protein powder if you’re dairy-free, or a vegan protein powder. You can also leave out protein powder and substitute it with 1 additional cup of almond flour.

Coconut Oil: Butter or ghee works great if you’re not avoiding dairy.

Maple Syrup: Honey or agave syrup will sweeten things up just as nicely while keeping it all-natural.

Salt: Sea salt, pink Himalayan salt, or even a pinch of flaky salt for a little extra texture would work perfectly here.

Cashew Butter: You can also use peanut butter, almond butter, or even sunflower seed butter will give you different, tasty variations for the caramel layer.

Pure Maple Syrup: Honey or agave syrup are good alternatives, keeping it naturally sweet while giving a slight flavor variation.

Coconut Oil: Butter or ghee can easily take coconut oil’s place if dairy isn’t a concern.

Vanilla Extract: You can use pure vanilla extract or imitation. A smaller amount of almond or maple extract adds a fun flavor switch if you’re out of vanilla.

Chocolate Chips: Use any variety of chocolate chips that meet your dietary needs, including dairy-free chocolate chips. You can also use dark chocolate chips, milk chocolate, or even sugar-free chocolate chips if you’re cutting back on sugar—any of these will melt down for the top layer.

How to Make My Gluten-Free Twix Candy Bar Recipe

Here are easy, detailed, step-by-step instructions for making my easy candy bars. The instructions are also repeated in the recipe card at the bottom of this blog post.

Step 1: Prepare the Cookie Layer

Preheat your oven to 350°F (170°C) and line a 8×8″ pan with parchment paper.

In a medium bowl, combine 1 cup almond flour, 1/2 cup protein powder, 3 tablespoons coconut oil (melted), 2 tablespoons maple syrup, 1-2 tablespoons milk, 1 teaspoon vanilla extract, and 1/4 teaspoon salt. Stir with a spatula until a thick dough forms similar to a cookie dough. Press the dough evenly into the bottom of the pan. Bake the shortbread layer for 10-11 minutes or until lightly brown on the edges.

Step 2: Make the Caramel Layer

In a small saucepan over low heat, melt together 2/3 cup cashew butter, 1/3 cup maple syrup, 1/4 cup coconut oil, 1 teaspoon vanilla extract, and 1/4 teaspoon salt. Stir with a whisk until smooth and fully combined. Pour the warm caramel mixture over the baked shortbread base and spread it evenly. Allow the pan to cool on the counter for atleast ten minutes. Then, place it in the freezer for at least 30 minutes or overnight to set it.

Step 3: Prepare the Chocolate Layer

In a microwave-safe bowl, combine 2/3 cup chocolate chips and 1-1/2 tablespoons coconut oil. Microwave in 30-second intervals, stirring in between, until the chocolate is fully melted and smooth. Pour the melted chocolate over the caramel layer and spread it evenly. Lightly sprinkle coarse sea salt over the chocolate. For best results, place the pan in the fridge for 10 minutes or until the chocolate is set. Then remove and slice into bars. Store leftovers in the fridge or freezer.

Expert Recipe Tips

Protein Powder Choice: Protein powders have different moisture levels. You may need to add slightly more flour or milk to your dough until it becomes a cookie dough consistency.

Chocolate Cracking: Freezing the bars before adding the chocolate layer helps the chocolate set quickly and makes the caramel and cookie layers easier to cut through. You can also freeze the entire pan with all the layers before slicing. Just let the bars thaw slightly on the counter, then use a sharp knife warmed under hot water to slice through the chocolate without cracking it.

Smaller Batch: You can make a half-batch and use a 4×8 loaf pan if you don’t need as many.

Delicious Serving Suggestions:

  • Date Caramel Layer: Swap out the usual caramel for a date caramel made from blended dates for a naturally sweet, sticky layer that pairs beautifully with the shortbread cookie crust.
  • Drizzle with Date Syrup: For an extra touch of sweetness, drizzle your Protein Twix Bars with date syrup. This adds a caramel-like flavor with a smooth, refined sugar-free finish.
  • Chunky Peanut Butter Boost: If you’re a peanut butter fan, spread a layer of chunky peanut butter between the shortbread and caramel layers for extra texture and richness. The peanut crunch adds a satisfying bite.
  • Butterscotch Chips or White Chocolate Chips: Melt butterscotch chips or white chocolate chips to drizzle over the top or use as part of the chocolate layer for a different twist on the traditional Twix bar.
  • Chopped Peanuts, Cashews, or Almonds: For a crunchy topping, sprinkle chopped peanuts, chopped cashews, or chopped almonds over the chocolate layer before it sets. This adds a nutty texture that contrasts perfectly with the smooth chocolate and caramel.
  • Cinnamon Touch: Add a dash of cinnamon to the cookie base or the caramel layer for a warm, cozy flavor that elevates these bars to another level.
  • Coconut Crunch: Toasted coconut flakes make a wonderful topping or can be mixed into the shortbread layer to give a hint of tropical flavor and added texture.

Refrigerator: Store your Twix Protein Bars in an airtight container in the fridge for up to one week. This will keep the layers firm and the flavors fresh.

Freezer: For longer storage, place the bars in a freezer-safe container or bag, and they’ll last up to one month. Thaw at room temperature for about 10-15 minutes before enjoying.

On-The-Go: If you’re taking them with you, keep the bars in a cooler or insulated bag to prevent the chocolate from melting.

Can I make these Twix protein bars without protein powder?
Yes, you can! If you prefer to leave out the protein powder, the bars will still taste great. Substitute it with 1 additional cup of almond flour.

What is the best substitute for almond flour in these homemade Twix bars?
I included a table in the Ingredients & Substitutions section with a chart of additional flour options.

Can I use a different nut butter for the mock caramel layer?
Definitely! Peanut butter, almond butter, or sunflower seed butter can be used instead of cashew butter. Each will give the bars a slightly different flavor, but they’ll still be delicious.

How do I prevent the candy bar chocolate layer from cracking when I slice the bars?
Freeze the pan after the first two layers. Pour on the melted chocolate and refrigerate it for 5 minutes until set. Then slice. You can also use a sharp knife and run it under hot water first so it’s warm.

Can I use dark chocolate instead of milk chocolate?
Yes, you can use dark chocolate, sugar-free chocolate, or dairy-free chocolate chips if you prefer a different flavor or want to customize the recipe to your tastes.

How should I store Twix protein bars?
Store your Twix protein bars in an airtight container in the fridge for up to a week. If you want to keep them longer, you can freeze them in a freezer-safe container for up to a month.

Can I make these Twix protein bars vegan?
Yes, you can make the bars vegan by using a plant-based protein powder and replacing the honey (if using) with maple syrup or agave. Be sure to use dairy-free chocolate chips as well.

Are these Twix protein bars customizable?
Yes! You can easily switch up ingredients like nut butter, chocolate, or even sweeteners to suit your personal preferences, making them as versatile as you’d like.

Choosing the Best Protein Powder for Your Twix Protein Bars

When it comes to selecting the right protein powder for baking, I often get asked about the best options. There are two main types of protein powders to choose from: animal-based and plant-based.

Animal-based protein powders are well-known for providing a complete amino acid profile, meaning they contain all the essential amino acids your body needs to build and repair tissues. Many people find that these proteins digest quickly, making them a popular choice for post-workout recovery. Personally, I tend to avoid animal-based powders since I already consume eggs regularly, try to limit dairy, and find beef protein to be pricey.

  • Whey protein
  • Casein protein
  • Egg protein
  • Beef protein
  • Collagen protein

Plant-based protein powders are a great option for those following a vegetarian or vegan lifestyle. They’re also a good choice for people looking for lower-fat, lower-cholesterol alternatives to animal-based powders. Although plant-based proteins don’t always contain all the essential amino acids in the same amounts as animal-based ones, combining different sources can help create a balanced profile. My favorites include pea, hemp, and nut proteins.

  • Pea protein
  • Brown rice protein
  • Hemp protein
  • Soy protein
  • Quinoa protein
  • Chia protein
  • Flaxseed protein

Sweeteners in Protein Powders

Protein powders come with a variety of sweeteners, and there are four key types to consider:

  • Artificial Sweeteners: These lab-made sweeteners, like aspartame and sucralose, are intensely sweet and calorie-free. I avoid these since they can sometimes cause digestive discomfort.
  • Sugar Alcohols: Naturally derived sweeteners like erythritol and xylitol offer sweetness with fewer calories but may cause stomach upset for some people. Personally, I steer clear due to how processed they are.
  • Natural Intense Sweeteners: Sweeteners like monkfruit and stevia are derived from natural sources and offer a high level of sweetness without calories or carbs. While I don’t mind using these, I find they can make my taste buds crave overly sweet flavors.
  • Traditional Sweeteners: Sweeteners like honey, maple syrup, cane sugar, and coconut sugar provide natural sweetness. These are my go-to options, but I always use them in moderation to keep my sugar intake balanced.

Choosing the best sweetener depends on your individual preferences and dietary needs. Feel free to experiment and see what works best for you! And as always, consult with a healthcare professional if you have specific concerns or dietary goals, especially when it comes to sweeteners and their effects on your overall health.
