Key ingredients

These lemon protein bars combine wholesome ingredients that support balanced nutrition and sustained energy, including:

Oat flour

Oat flour brings a hearty, whole grain foundation to these bars. Naturally gluten-free when certified as such, it provides complex carbohydrates and fiber that help support stable blood sugar and digestive health.

Vanilla protein powder

Protein powder boosts each bar’s protein content, helping with muscle repair and satiety. Using a vanilla variety enhances flavor while contributing essential amino acids, especially when choosing high-quality whey or bone broth options.

Egg whites

Egg whites are lean protein powerhouses, adding volume and structure without fat or cholesterol. They help make these bars satisfying and rich in muscle-supporting protein.

Stevia

Stevia is a natural, zero-calorie sweetener that adds sweetness without spiking blood sugar. A little goes a long way, keeping these bars lower in added sugars than traditional baked goods.

Applesauce

Unsweetened applesauce brings moisture and natural sweetness while reducing the need for refined sugars or oils. It adds fiber and helps bind the ingredients together for a tender texture.

This lemon protein bars recipe also includes sea salt, baking soda and lemon juice, which provide additional flavor and benefits, as well as a touch of coconut oil to prevent sticking.
