Tools You’ll Need

Here are the tools you’ll need to make these Protein Twix Bars:

• 8×8 inch baking pan
• Parchment paper
• Food processor or high-powered blender

How to Make Protein Twix Bars

These Protein Twix Bars come together in just a few simple steps. Let’s get started!

Step 1: Prep

Set the oven to 350°F (175°C). Prepare an 8×8-inch pan by lining it with parchment paper, allowing the edges to hang over slightly for easier lifting later.

Step 2: Cook

In a food processor, blend the almond flour, pecans, cinnamon, and a pinch of salt until it forms a coarse, sandy texture. Add the melted coconut oil and honey, and pulse until a sticky dough forms. Press this mixture evenly into the prepared pan.

Step 3: Assemble

In a small saucepan, combine the peanut butter, coconut oil, and maple syrup. Warm the mixture over medium heat, stirring constantly, until smooth and glossy. This creates a rich, caramel-style filling without the need for cooked sugar. Pour it over the shortbread base and spread evenly.

Step 4: Finish

Gently melt the dark chocolate using a double boiler or short microwave intervals, stirring until glossy and smooth. Spread it evenly over the caramel layer with a spatula, then finish with a light sprinkle of flaky sea salt.

Protein Twix Bars Variations

Extra-decadent version:
For a richer, dessert-style bar, add a tablespoon or two of butter to the peanut butter caramel layer and use a higher-fat dark chocolate for the topping. This creates a silkier center and a more pronounced chocolate snap when chilled.

Lower-sweetness option:
If you prefer a less sweet bar, reduce the honey and maple syrup slightly and choose an unsweetened nut butter. The bars will still set beautifully while letting the toasted nuts and chocolate shine.

Flavor twists:
Stir a pinch of flaky salt or espresso powder into the chocolate layer, or add vanilla extract to the caramel filling for extra depth. These small tweaks keep the bars interesting without changing the overall method.

High-Protein Boost (Optional):
For an extra protein boost, you can blend 1–2 scoops of unflavored or vanilla protein powder into the peanut butter caramel layer. If the mixture thickens, add 1–2 tablespoons of warm coconut oil to keep it smooth and spreadable.

Chef’s Tips for the Best Protein Twix Bars

Here are a few tips to help you achieve the best Protein Twix Bars:

• Be patient: When making the caramel layer, low and slow is the key to achieving the perfect silky-smooth texture.
• Toast the nuts: Toasting the pecans before blending intensifies their flavor and creates a deeper, more complex base for the bars.
• Indulge with chocolate chips: For an extra-indulgent twist, sprinkle a handful of mini chocolate chips into the caramel layer before pouring it over the shortbread.
• Dress it up: Finish the bars with a light dusting of cocoa powder or a drizzle of melted white chocolate for a professional-looking presentation.

Serving & Storage

Serve with: a scoop of vanilla ice cream, a dollop of whipped cream, a fresh fruit salad, or a steaming mug of coffee or hot chocolate.

Storage: Store the Protein Twix Bars in an airtight container in the refrigerator for up to 1 week. For longer-term storage, wrap the bars individually in parchment or wax paper and place them in a freezer-safe bag or container for up to 3 months.

Reheat: When ready to enjoy, simply thaw the bars at room temperature for 30 minutes or pop them in the microwave for 10-15 seconds.

Make-Ahead: Prepare the shortbread base and caramel layers in advance, then store them separately in the fridge. When you’re ready to assemble, simply pour the caramel over the shortbread, top with chocolate, and let the layers set.
