Ingredients
- •Peanut Butter, Smooth(180g)
- •Honey(80g)
- •Coconut oil(30g)
- •Oats, Rolled, Dry(480g)
Old-fashioned rolled oats (not instant, not steel-cut). Quaker is standard.
- •Whey protein powder (vanilla)(120g)
Use whey isolate for cooking. Vanilla flavor is most versatile.
- •Flaxseed, Ground (Flaxseed Meal)(45g)
- •Cinnamon, Ground(1g)
- •¼ teaspoon kosher salt
- •Chocolate Chips, Semisweet(80g)
Instructions
- 1Line an 8x8- or 9x9-inch baking pan with parchment paper, leaving an overhang on two sides for handles.
- 2Place the peanut butter, honey, and coconut oil in a medium heatproof bowl. Set the bowl over a saucepan of simmering water (do not let the water boil or touch the bottom of the bowl). Heat over medium to medium-high heat, stirring frequently, for 3–5 minutes until the mixture is smooth and fully combined. Remove the bowl from the saucepan and turn off the heat.
- 3Add the rolled oats, vanilla whey protein powder, ground flaxseed, cinnamon, and salt to the warm peanut butter mixture. Stir vigorously for 2–3 minutes until fully combined; the mixture will seem dry at first but will come together into a cohesive dough that holds its shape when pressed.
- 4If the mixture is still warm, refrigerate for 5–10 minutes until cooled slightly. Fold in the chocolate chips until evenly distributed throughout.
- 5Transfer the mixture to the prepared pan and press firmly and evenly into all corners using a spatula or your hands until compact and level. Refrigerate for 1 hour or until firm to the touch.
- 6Lift the bars from the pan using the parchment handles and transfer to a cutting board. Slice into 12 equal bars using a sharp knife, wiping the blade between cuts for clean edges.
- 7Divide evenly into 6 airtight containers while still cool, storing 2 bars per container. Refrigerate for up to 7 days.
