Chocolate Chip Protein Blondies Recipe

Prep Time: 10 minutes | Blend Time: 20 minutes | Total Time: 30 minutes

This protein blondies recipe delivers that golden, chewy, caramel-like bite you crave, only smarter. We fold almond flour, ripe banana, dark chocolate chips, and vanilla Purimo whey protein into a batter that bakes up dense, soft, and satisfyingly sweet. Purimo Pure Whey blends premium whey concentrate and isolate, is naturally sweetened with stevia, and provides 22 g protein per 30 g serving, so your protein blondies work just as hard as you do.

Ingredients

• 180 g almond flour (extra-fine)
• 60 g Purimo Pure Whey (vanilla)
• 1 tsp baking powder
• 1/4 tsp fine sea salt
• 2 large eggs, room temperature
• 200 g ripe banana, well-mashed (about 2 medium)
• 60 g melted coconut oil (or 50 g light olive oil)
• 1 tsp vanilla extract
• 90 g dark chocolate chips (60–70% cocoa)
• Optional: 30 g chopped walnuts for extra crunch

Notes and smart swaps:

• Sweeter, lower-sugar option: Replace banana with 60 g xylitol or erythritol and add 80–100 ml milk (dairy or unsweetened almond) to match batter moisture.
• Higher protein: Increase Purimo Pure Whey to 75 g and add 20–30 ml extra milk to keep the batter scoopable.

Method

1. Prep. Heat oven to 175°C (fan 160°C). Line an 20 cm square tin with baking paper, overhanging two sides for easy lifting.
2. Dry mix. In a large bowl, whisk almond flour, Purimo Pure Whey, baking powder, and salt until evenly combined.
3. Wet mix. In a separate bowl, whisk eggs, mashed banana, melted coconut oil, and vanilla until smooth.
4. Combine. Fold the wet mix into the dry until just combined. The batter will be thick. Fold in chocolate chips (and walnuts, if using).
5. Bake. Spread evenly into the lined tin. Bake 18–22 minutes until the top is set, edges are lightly golden, and a skewer comes out with a few moist crumbs.
6. Cool and slice. Cool in the tin for 15 minutes, then lift out and cool fully. Slice into 16 squares for snack-size protein blondies.
7. Store. Keep in an airtight container: 3 days at room temp, 5–6 days chilled, or freeze up to 2 months.
