Ingredients 

Lemon Loaf

  • 1 cup sugar
  • 3 large eggs, whisked
  • 10 tbsp milk, for dairy-free. use unsweetened almond milk or coconut milk
  • 10 tbsp unsalted butter, melted, sub ghee or Smart Balance butter for a dairy-free option
  • ¼ cup lemon juice, freshly squeezed
  • ½ tbsp lemon zest
  • 1 tsp vanilla extract
  • cups gluten-free all-purpose flour blend, with xanthan gum—I like Pillsbury gluten-free flour blend
  • 2 tsp baking powder
  • ¼ tsp salt

Lemon Icing

  • 1 cup powdered sugar, sifted
  • 1-2 tbsp lemon juice, adjust for thickness
  • tsp salt

Instructions 

  • Preheat oven to 350°F. Grease and line a loaf pan with parchment paper.
  • In a large bowl, whisk sugar and eggs until light and frothy, about 1 minute.
  • Add milk, butter, lemon juice, lemon zest, and vanilla to the egg mixture and whisk until smooth.
  • Add the gluten-free flour, baking powder, and salt. Gradually stir in the dry ingredients until just combined. Do not overmix.
  • Pour the batter into the prepared loaf pan and smooth the top.
  • Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
  • For the icing, whisk powdered sugar, lemon juice, and salt until smooth. Drizzle over the cooled loaf.
  • Let the glaze set before slicing. Serve and enjoy!

Notes

  • Fresh lemon juice is highly recommended for the best flavor. Bottled lemon juice can taste flat and overly acidic.
  • To test if the loaf is done, the toothpick should come out clean or with moist crumbs. The top should spring back when touched.

Serving Suggestions

This gluten-free iced lemon loaf is perfect with a cup of coffee or tea for a bright morning snack. I love adding it to brunch spreads along with other treats like gluten-free blueberry scones and gluten-free danish. Or serve a slice with fresh berries and whipped cream for an easy spring dessert. 

Storage Instructions

To store your gluten-free iced lemon loaf, wrap it tightly and keep it at room temperature for up to 2 days. For longer storage, place it in an airtight container in the fridge for up to 5 days. 

You can also freeze the fully cooled loaf or individual slices—just wrap them in plastic wrap and foil, then freeze for up to 2 months. For best results, thaw at room temperature and add the glaze after thawing.
