Beet and Orange Chocolate Hazelnut Bars

These beet and orange bars are fudgy, moist, and a deep jewel red, with a cocoa-rich flavor and a bright citrus lift. Finely grated beets melt into the batter, adding moisture, natural sweetness, and that gorgeous color, while orange zest and juice keep the flavor fresh. A scattering of toasted hazelnuts on top adds crunch, and the bars are made with oat flour and honey instead of wheat flour and white sugar.

If you have ever baked chocolate beet cake, you know that beets and cocoa are a perfect pair. The earthy sweetness of the beets deepens the chocolate, and a little orange makes the whole bar taste like a classic chocolate orange. These bars are simple to make, with one bowl for the wet ingredients and one for the dry, and they cut into neat squares that are ideal for lunchboxes, snack plates, and dessert trays.

What Do Beet and Orange Bars Taste Like?

These bars taste like a moist chocolate brownie with a subtle orange note. The beets are not obvious as a vegetable. Instead, they give a mellow, earthy sweetness that rounds out the cocoa. The orange zest adds a clean citrus fragrance, the honey lends a gentle floral sweetness, and the hazelnuts add a buttery crunch. The texture is dense, soft, and slightly chewy.

Recipe Overview

• Prep time: 20 minutes
• Bake time: 30 to 35 minutes
• Yield: 16 bars from a 9×9-inch pan
• Difficulty: Easy
• Method: One-pan baked bar

Ingredients

PIN IT

• 1 1/2 cups (about 250 g) finely grated raw beets (about 2 medium beets, peeled)
• 3 large eggs
• 1/3 cup (80 ml) neutral oil
• 1/3 cup (115 g) honey or maple syrup
• 1/4 cup (60 ml) fresh orange juice
• 1 tablespoon orange zest
• 1 teaspoon vanilla extract
• 1 1/4 cups (115 g) oat flour (rolled oats ground to a fine flour)
• 1/3 cup (35 g) unsweetened cocoa powder
• 1 teaspoon baking powder
• 1/4 teaspoon salt
• 1/2 cup (60 g) chopped hazelnuts, divided

Ingredient Notes

Beets: Use raw beets, peeled and grated on the small holes of a box grater or in a food processor. The finer the grate, the smoother the bars. Wear gloves or an apron, since beet juice stains.

Oat flour: Blend rolled oats in a food processor or blender until fine. Use certified gluten-free oats if you need the bars to be gluten-free.

Cocoa powder: Unsweetened natural or Dutch-process cocoa both work. Sift it if it is lumpy.

Honey or maple syrup: Either one sweetens the bars gently. The beets also add sweetness, so the bars do not need much.

Orange: Zest the orange before juicing it. Fresh juice and zest give the best flavor.

Hazelnuts: Toast them in a dry skillet for a few minutes and rub off the loose skins for the best flavor. Walnuts or almonds can replace them.

Kitchen Tools You’ll Need

• 9×9-inch baking pan
• Parchment paper
• Box grater or food processor with a grating disc
• Blender or food processor for the oat flour
• Two mixing bowls and a whisk
• Rubber spatula
• Zester or fine grater and a wire cooling rack

Substitutions and Variations

• Nut-free: Top the bars with pumpkin seeds or leave off the nuts entirely.
• Chocolate chips: Fold in 1/3 cup of dark chocolate chips for a more decadent bar.
• Orange glaze: Drizzle with a simple glaze of powdered sugar and orange juice for a sweeter finish.
• Different nuts: Use walnuts, almonds, or pecans in place of the hazelnuts.
• Dairy-free: The bars already contain no dairy, so they only need an egg-free swap to be vegan, which has not been tested here.
• Cooked beets: Pureed cooked beets can replace the raw grated ones, but use about 3/4 cup and reduce the juice slightly.

How to Make Beet and Orange Bars

The method is simple: whisk the wet ingredients, stir in the beets, fold in the dry ingredients and half the nuts, spread, top, and bake. The batter is thick, which is exactly right for bars.

Step-by-Step Instructions

PIN IT

1. Prepare the pan. Preheat the oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving an overhang on two sides.
2. Mix the wet ingredients. In a large bowl, whisk the eggs, oil, honey, orange juice, orange zest, and vanilla until smooth.
3. Add the beets. Stir in the grated beets.
4. Add the dry ingredients. In a separate bowl, whisk the oat flour, cocoa powder, baking powder, and salt. Add to the wet ingredients and stir until just combined. Fold in half of the chopped hazelnuts.
5. Fill the pan. Spread the thick batter evenly in the pan and sprinkle with the remaining hazelnuts.
6. Bake. Bake for 30 to 35 minutes, until the center is set and a toothpick inserted in the middle comes out with a few moist crumbs.
7. Cool and cut. Cool completely in the pan. Lift out using the parchment and cut into 16 bars.

Tips for Success

• Grate the beets finely and pat them gently with a paper towel if they are very juicy.
• Do not overmix once the dry ingredients go in, which can make the bars gummy.
• Press the top hazelnuts lightly into the batter so they stay on when you slice.
• Let the bars cool fully before cutting for clean edges.
• Chill the bars for an hour for the fudgiest, easiest-to-slice texture.
• Check the bars at 30 minutes, since moist beet batters can bake quickly.
• Use a sharp knife and wipe it between cuts.

How to Know They’re Done

The bars are done when the edges are set, the top looks dry and slightly cracked, and a toothpick inserted in the center comes out with a few moist crumbs. They should not jiggle in the middle. They firm up as they cool.

What to Serve With Beet and Orange Bars

These bars are lovely on their own, and even better with:

• A spoonful of Greek yogurt or whipped cream
• Fresh orange segments
• Hot coffee or herbal tea
• A cold glass of milk

Storage Instructions

Store the bars in an airtight container in the refrigerator for up to 5 days, with parchment between the layers. They are fudgiest when chilled and can be brought to room temperature for 15 minutes before serving. Keep the hazelnut topping crisp by adding extra nuts just before serving.

Freezing Instructions

Freeze the cooled, cut bars in a single layer on a tray until firm, then transfer them to a freezer bag for up to 3 months. Thaw in the refrigerator overnight or at room temperature for about 30 minutes.

Common Mistakes

• Grating the beets too coarsely. Large shreds make the bars uneven and wet.
• Overbaking. It dries out the bars and loses the fudgy texture.
• Using pickled beets. They are too sour and too wet for baking.
• Skipping the zest. The orange flavor comes mainly from the zest.
• Cutting while warm. The bars are soft and tear instead of slicing cleanly.
• Coarse oat flour. Grind the oats well so the bars are tender, not gritty.

Frequently Asked Questions

Can you taste the beets?

Only faintly. The cocoa and orange balance the earthy flavor, so most people notice a rich chocolate bar with a hint of sweetness.

Are these bars gluten-free?

They contain no wheat flour, but oats can be cross-contaminated. Use certified gluten-free oats if you need them gluten-free.

Do they contain sugar?

They have no white sugar, but they are sweetened with honey or maple syrup, along with the natural sugars in beets and orange juice.

Can I use cooked beets?

Raw grated beets are recommended. If you use cooked beets, puree them and reduce the orange juice slightly.

Can I make them without eggs?

The eggs bind the bars and give structure, so substitutions have not been tested here.

Why are my bars so moist?

Beets hold a lot of water. Chill the bars well and make sure they bake until the center is set.

Recipe Background

Beets have a long history in baking, especially in chocolate cakes, where their moisture and natural sweetness help create tender, fudgy results. Pairing chocolate with orange is a classic combination found in European confectionery and desserts. Published beetroot, orange, and chocolate desserts range from no-bake tarts to baked cakes, and this Poulef version turns the idea into easy baked bars with oat flour, honey, and hazelnuts.

Conclusion

Beet and orange bars prove that vegetables can be the secret to a better dessert. They are fudgy, fragrant, and beautifully red, with a bright citrus finish and a crunchy hazelnut top. Bake a pan for your next snack table, and enjoy a treat that tastes indulgent but feels a little lighter.
