Step-by-Step Instructions

1. Prepare the Batter
Preheat your oven to 350°F (175°C). Line a loaf pan (8×4-inch) with parchment paper and lightly grease it.
In a large bowl, whisk together:
-
1¾ cups almond flour
-
2 tbsp coconut flour
-
1½ tsp baking powder
-
¼ tsp salt
In another bowl, beat:
-
4 large eggs
-
½ cup melted butter (or coconut oil)
-
⅔ cup erythritol or monk fruit sweetener
-
2 tbsp lemon zest
-
¼ cup lemon juice
-
1½ tsp vanilla extract
Combine wet and dry ingredients until smooth. Let the batter sit for 2–3 minutes to allow the coconut flour to absorb moisture.
2. Bake the Bread
Pour the batter into the prepared loaf pan. Smooth the top with a spatula.
Bake for 45–50 minutes, or until golden and a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then transfer to a wire rack.
3. Glaze & Finish
In a small bowl, whisk:
-
½ cup powdered erythritol
-
1–2 tbsp lemon juice
-
Optional: 1–2 tsp almond milk for thinner glaze
Drizzle over the cooled lemon bread. Let set for 10 minutes before slicing.

FAQs
Q1: Can I use all almond flour and skip coconut flour?
A1: It’s best to keep both. Coconut flour absorbs liquid differently and helps with texture. If omitting, increase almond flour slightly and reduce liquid.
Q2: Can I make this lemon bread dairy-free?
A2: Yes! Use coconut oil or a dairy-free butter substitute in equal amounts.
Q3: Why did my lemon bread sink in the middle?
A3: This can happen from underbaking or overmixing. Check your baking powder is fresh, and be sure to let the bread bake fully before removing.
Q4: Can I freeze this bread?
A4: Absolutely. Slice it, wrap tightly, and freeze up to 2 months. Thaw overnight or warm in the microwave.
Q5: Is it safe for diabetics?
A5: Yes — it’s made with low-glycemic sweeteners like erythritol or monk fruit. Always check with a healthcare provider for individual guidance.
Q6: Can I make muffins instead?
A6: Yes. Divide the batter into muffin cups and bake at 350°F for 18–20 minutes.
Q7: Can I double the recipe?
A7: Yes, but bake in two separate pans. Increase baking time slightly and check for doneness.
