Soften the Butter. Allow the unsalted butter to come to room temperature. This makes it easier to blend with the maple syrup.
Mix Maple Syrup and Butter. In a mixing bowl, combine the softened butter and pure maple syrup. Add a pinch of salt to enhance the flavors.
Blend Until Creamy. Use an electric mixer or a hand whisk to blend the mixture. Start on low speed to prevent splattering, then gradually increase to medium-high. Beat until the mixture is smooth and creamy.
Taste and Adjust. Give your maple butter a taste test. If you'd like it sweeter, add more maple syrup. For a deeper maple flavor, add a touch of pure maple extract.
