Ingredients List

For the Muscle Bar Base

  • 1 ½ cups oat flour (or almond flour for low-carb)
  • 2 scoops vanilla or chocolate protein powder
  • ½ cup natural peanut butter (or almond butter)
  • ¼ cup sugar-free maple syrup (or honey for non-keto)
  • ¼ cup unsweetened almond milk
  • 1 teaspoon vanilla extract
  • Pinch of salt

For the Chocolate Protein Topping

  • 1 cup sugar-free chocolate chips
  • 1 tablespoon coconut oil
  • 1 tablespoon protein powder (to thicken and add texture)

Instructions

Step 1: Prepare the Base

Mix dry ingredients:
In a large bowl, combine oat (or almond) flour, protein powder, and a pinch of salt.

Add wet ingredients:
Add peanut butter, sugar-free maple syrup, and vanilla. Mix until crumbly.

Add almond milk:
Pour in almond milk slowly and mix until it forms a thick, dough-like texture.

Press into pan:
Line an 8×8 dish with parchment paper and firmly press the mixture down into an even base layer.

Step 2: Make the Chocolate Topping

Melt chocolate & coconut oil in the microwave or over a double boiler.

Whisk in protein powder until smooth and glossy.

Pour the chocolate topping over the base and spread evenly.

Step 3: Chill & Slice

Refrigerate for at least 1 hour or freeze for 20 minutes.

Once firm, lift using the parchment paper and slice into 10–12 bars.

Additional Notes

  • If mixture is too thick → add 1 tbsp more almond milk.
  • If mixture is too soft → add 1–2 tbsp extra oat or almond flour.
  • Use a metal spatula to firmly press the base so it binds properly.

Optional Personal Story

I started making these Muscle Bars on days when I wanted a clean, high-protein snack without grabbing packaged bars. After a few tweaks, I realized they tasted even better than store-bought ones — softer, richer, and far more satisfying. Now I keep a batch in the fridge every week for workouts, cravings, and busy days.
