Homemade Protein Bar Recipe Card

Ingredients

Here’s what you’ll need to make your own high-protein slice:

• 2 cups rolled oats (blended into oat flour): Provides fibre and structure.

• 1 cup natural peanut butter (or almond butter): Adds creaminess, healthy fats, and flavour.

• ½ cup honey or maple syrup: A natural sweetener that helps bind ingredients.

• 1 scoop (30g) WPI: Whey Protein Isolate Powder or Premium Plant Vegan Protein Powder: The key protein bar ingredient for that high-protein boost.

• ½ cup unsweetened almond milk: Keeps the mixture soft and easy to shape.

• 1 tsp vanilla extract: Enhances flavour naturally.

• ¼ cup dark chocolate chips (optional topping): For that lipsmacking finish.

• Pinch of sea salt: Balances flavours.

Method (Step-by-Step)

1. Make oat flour by blending rolled oats into a fine flour. This replaces refined flour, keeping the recipe wholesome and nutritious.

2. Mix the wet ingredients: In a mixing bowl, stir together peanut butter (or almond butter), honey, and almond milk until smooth. This step ensures your bars will hold together.

3. Add protein powder: Stir in your choice of WPI - Whey Protein Isolate Powder (great for low-carb, quick-absorbing bars) or Premium Plant Vegan Protein Powder (for a dairy-free, plant-based option).

4. Combine with oat flour: Slowly mix in the oat flour until a thick, dough-like mixture forms. It should be sticky but manageable.

5. Shape the mixture: Press it firmly into a lined baking dish so the bars hold their shape.

6. Optional topping: Melt dark chocolate and drizzle over the top, or press in chocolate chips before chilling.

7. Chill to set: Place in the fridge for at least 1-2 hours before slicing into bars.

And your protein bars are ready!
