How to Make Orange, Pistachio & Almond Grain-Free Cake Recipe

Step 1: Prepare the Orange Puree

Start by thoroughly rinsing your oranges to remove any residue, then place them whole in a pot and cover with water. Simmer gently over low heat for an hour. This slow simmer softens the oranges completely, mellowing their natural bitterness and releasing fragrant oils. Afterward, drain the water and blend the oranges into a smooth puree. This pureed citrus base is the secret to the cake’s moist texture and vibrant flavor.

Step 2: Grind the Pistachios

While the oranges cook, grind your pistachios until they are finely powdered, using a coffee grinder or food processor. This fine texture ensures the nuts integrate seamlessly into the batter, contributing a gentle crunch and a beautiful green hue that complements the almond flour perfectly.

Step 3: Mix the Batter

Preheat your oven to 175°C (350°F) and grease a loose-bottom cake pan for easy release later. In a large bowl, whisk together the orange puree, eggs, honey, ground pistachios, almond flour, vanilla extract, and baking soda. Stir just until combined — overmixing can affect texture — and pour the batter into your prepared pan.

Step 4: Bake Your Cake

Bake the cake for about one hour. Keep an eye on the top; if it starts browning too quickly, place foil over it to prevent burning while the inside finishes cooking. The cake is done when a skewer inserted into the center comes out clean, signaling that dense, moist crumb we crave.

Step 5: Prepare and Apply the Orange Honey Glaze

While baking, simmer the orange juice and honey in a small pot until reduced by half, concentrating the sweetness and bright citrus flavor. Once the cake is out of the oven, brush this glossy glaze generously all over the surface. Top with dried orange slices for a stunning presentation and an extra burst of citrus aroma. With a gentle tap of a knife along the edges, release your cake from the pan, and you’re ready to impress!

Garnishes

This cake shines beautifully with simple garnishes. Fresh pistachios sprinkled on top add crunch and color contrast, while a few sprigs of mint bring a fragrant freshness. You can also use candied orange peel for an elegant and sweet citrus boost that keeps the theme bright and inviting.

Side Dishes

Pair this grain-free cake with light accompaniments that won’t overpower its delicate flavors. A dollop of lightly whipped cream or a spoonful of Greek yogurt with a drizzle of honey creates a creamy balance. Fresh berries or a simple fruit salad also complement the nutty, citrus richness perfectly.

Creative Ways to Present

Try serving individual slices with a small drizzle of orange-honey glaze and a sprinkle of crushed pistachios on each plate for a restaurant-style touch. Or, turn the cake into mini trifle jars, layering bite-sized pieces with mascarpone and orange segments for a charming dessert twist. Every approach makes this cake feel special and memorable.

Make Ahead and Storage

Storing Leftovers

This grain-free cake keeps wonderfully fresh when wrapped tightly in plastic wrap or stored in an airtight container at room temperature for up to three days. For longer freshness, refrigeration is best, where it will stay moist and delicious for about a week.

Freezing

If you want to enjoy this cake later, it freezes beautifully. Wrap the cooled cake securely in plastic wrap and then foil before freezing. Thaw overnight in the fridge when you’re ready to indulge, and it will taste just as fresh as the day you baked it.

Reheating

To bring back that freshly-baked warmth, reheat slices gently in the oven at a low temperature (about 150°C / 300°F) for 10 minutes or until warmed through. Avoid microwaving if you want to preserve texture—it can make the cake a bit rubbery. A slight crispiness on the edges is a welcomed bonus when reheated this way!

FAQs

Can I use sweetened orange juice instead of fresh oranges?

Fresh oranges are key to the authentic texture and brightness of this cake. Sweetened orange juice won’t provide the same pulp fullness and might affect the moisture balance, so it’s best to stick with the original fresh fruit for that perfect result.

Is it possible to substitute almonds or pistachios?

While almonds and pistachios offer a unique flavor and texture profile, you could experiment with other nuts like walnuts or cashews. Keep in mind, each nut varies in oil content and grind texture, so the cake’s moistness and flavor may change slightly.

How can I make dried orange slices at home for the topping?

Thinly slice an orange (about 0.5 cm thick), place slices on parchment paper, and bake at 150°C (300°F) for around an hour. Flip halfway to prevent burning. These dried slices add a gorgeous decorative touch and intensify the orange aroma on your cake.

Can this cake be made vegan?

This recipe depends on eggs for structure and honey for sweetness, which aren’t vegan. However, flax eggs and maple syrup or agave nectar might be interesting substitutions to try, though texture and flavor will vary from the original.

What’s the best pan to use for this cake?

A loose-bottom cake pan is ideal to ensure easy removal without damaging the delicate cake edges. If you don’t have one, a springform pan or a well-greased round cake pan with parchment paper will also work nicely.
