Ingredients for Gluten Free Lemon Poppy Seed Blackberry Cake

1 1/2 cups almond flour: Offers a nutty flavor and moist texture, serving as the backbone of this cake.
1/2 cup coconut flour: Absorbs moisture and adds a hint of sweetness; ensure not to substitute it directly for almond flour due to its high absorbency.
1/4 cup poppy seeds: Adds a delightful crunch and nutty flavor, essential for that classic lemon poppy seed combination.
1 teaspoon baking powder: Ensures your cake rises beautifully, achieving a light and airy texture.
1/2 teaspoon salt: Elevates the sweetness and balances flavors perfectly.
3/4 cup honey or maple syrup: Natural sweeteners that impart unique flavors and moisture to the cake.
1/2 cup coconut oil, melted: Adds richness while keeping the cake moist; can also be substituted with another light oil like canola.
4 large eggs: Acts as a binder, providing structure and moisture to the cake.
1/4 cup lemon juice: Infuses a bright, tangy flavor that complements the sweetness.
Zest of 1 lemon: Intensifies the citrus aroma, enhancing the overall taste experience.
1 cup fresh blackberries: Bursting with juicy goodness, they add vibrant flavor and color to the cake.

Feel free to experiment with the sweetness by adjusting the honey or maple syrup to your preference, or swap out the blackberries for raspberries or blueberries for a different twist.

How to Make Gluten Free Lemon Poppy Seed Blackberry Cake

Preheat your oven to 350°F (175°C). Grease your 9-inch round cake pan with a bit of coconut oil or line it with parchment paper for easy release.
In a large mixing bowl, whisk together 1 1/2 cups almond flour, 1/2 cup coconut flour, 1/4 cup poppy seeds, 1 teaspoon baking powder, and 1/2 teaspoon salt until well combined.
In another bowl, whisk together 3/4 cup honey (or maple syrup), 1/2 cup melted coconut oil, 4 large eggs, 1/4 cup lemon juice, and zest of 1 lemon until smooth and creamy.
Gently pour the wet mixture into the dry ingredients, stirring until just combined—be careful not to overmix! Add 1 cup fresh blackberries, folding them in gently to preserve their shape.
Transfer the batter into your prepared cake pan, smoothing the top with a spatula. Ensure it’s evenly distributed to promote even baking.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The top should be lightly golden and might feel springy to the touch.
Allow the cake to cool in the pan for about 10 minutes before running a knife around the edges and carefully inverting onto a wire rack to cool completely.

Chef’s Notes & Helpful Tips

Make-ahead tips: You can prepare the batter a day in advance and store it in the fridge. Just let it come to room temperature before baking for the best results.
Cooking alternatives: Try using an air fryer for a quicker baking time, adjusting the temperature to about 320°F (160°C) and checking for doneness a few minutes earlier.
Customization ideas: Add a splash of vanilla extract for a warmer flavor profile, or sprinkle additional poppy seeds on top before baking for an attractive finish.

Common Mistakes to Avoid

Overmixing the batter: This can lead to a dense, gummy texture. Mix just until combined.
Not letting ingredients come to room temperature: Cold eggs or coconut oil can affect the cake’s rise and texture, so plan accordingly.
Skipping the cooling step: Allowing the cake to cool helps set its structure and flavor, enhancing the overall eating experience.

Nut butter: A dollop of almond or cashew butter creates a delightful contrast of flavors.
Sliced strawberries: Their sweetness plays beautifully with the cake’s tart notes.

FAQs

Can I substitute the almond flour?
Absolutely! Sunflower seed flour is a great nut-free alternative, though be mindful of the green tint it may impart when baked.

How do I ensure my cake is moist?
Incorporate enough wet ingredients and avoid overbaking. The cake will further retain moisture as it cools, so don’t skip that step!

Can I make this cake egg-free?
Yes! Use a flax egg or chia egg as a substitute. Combine 1 tablespoon of ground flaxseed or chia seeds with 2.5 tablespoons of water, let it sit until it thickens, and then mix it into the batter.

What if I don’t have fresh blackberries?
Frozen blackberries work just as well! Just toss them in a bit of flour before adding them to the batter to prevent them from sinking.

Can I double this recipe?
Certainly! For a larger gathering, double the ingredients and bake in a bigger pan or two separate cakes. Adjust the baking time accordingly.
