Keto Chocolate Sunflower Butter Stuffed Cookie Bars

Staying keto through the holidays can feel challenging. Between gatherings, office parties, and well-meaning friends and family who don’t always get low-carb food, it’s easy to feel tempted or sidelined. These Keto Chocolate Sunflower Spread Stuffed Cookie Bars change that — they’re rich, chocolatey, and entirely keto-friendly, so you can bring a dessert everyone will love without compromising your goals.

These cookie bars are a sandwich-style dessert with a sugar-free chocolate sunflower spread sandwiched between two cookie layers. The dough is baked in an 8×8 pan, cooled, and cut into bars. By swapping traditional sugar and wheat flour for low-carb alternatives, these bars deliver the classic cookie-bar experience with keto macros.

They’re so indulgent that guests likely won’t guess they’re low carb. After one bite, you’ll be giving out the recipe and getting requests to make a batch for the next get-together.

Say Hello to Chocolate Sunflower Spread

Chocolate sunflower spread is a sugar-free alternative to popular chocolate-hazelnut spreads. Made from sunflower seeds and sweetened with monk fruit and erythritol, it’s typically nut-free, dairy-free, and gluten-free. A small serving often has only about two grams of net carbs and no added sugar, making it a great keto-friendly filling. Stir the jar well before using; natural separation can leave oil on top.

The Crust

The best cookie bars balance a tender interior with a slight crunch. Using a mix of two low-carb flours keeps texture rounded and avoids letting one flour’s flavor dominate.

Almond Flour

Blanched almond flour is the closest keto replacement for all-purpose flour in many recipes. It’s ideal for baking and provides a moist crumb. Note the difference between almond flour and almond meal — choose finely ground blanched almond flour for the best texture.

Coconut Flour

Coconut flour is very absorbent and helps firm up the dough. Batters with coconut flour sometimes look thin at first but thicken after a few minutes as the flour absorbs moisture. These flours are not swapped one-for-one with wheat flour, so follow the recipe for correct ratios.

Sea Salt

A sprinkle of quality sea salt on top brightens flavors and highlights the chocolate. Avoid iodized table salt for baking; choose a coarse or kosher sea salt for topping and better texture.

The Mixture

Almond and coconut flours soak up moisture differently, so getting the wet-to-dry balance right matters. The recipe below has been adjusted to yield a moist, sliceable crust without crumbliness.

Sugar-Free Sweeteners

To keep these bars keto, use sugar alternatives. For a brown-sugar flavor, use a sugar-free brown sweetener (monk fruit blended with erythritol and flavoring works well). For granulated replacement, monk fruit or erythritol blends give the best baking results and maintain moisture.

Sunflower Seed Butter

For both flavor and texture, creamy sunflower seed butter is used in the dough. It pairs naturally with the sunflower spread filling and keeps the recipe nut-free. Stir natural butters before measuring to incorporate separated oil. You can substitute other creamy nut butters if you prefer.

Chocolate Chips

Use quality sugar-free chocolate chips so the bars have pockets of melty chocolate without added sugar. Choose chips that hold up during baking yet soften into gooey bites.

Let’s Make Keto Chocolate Sunflower Spread Stuffed Cookie Bars

Preheat your oven to 350°F (175°C) and line an 8×8-inch square pan with parchment paper for easy removal. Below are clear, step-by-step instructions to assemble and bake the bars.

Making Cookie Bar Dough

Start with two bowls. In one bowl whisk together the almond flour, coconut flour, baking powder, and sea salt. In the other, mix sunflower seed butter, softened coconut oil, sugar-free brown sweetener, and granulated sweetener until smooth. Add eggs and vanilla and stir until glossy and combined. Fold the dry ingredients into the wet mixture until mostly combined, then fold in the chocolate chips. Avoid over-mixing to prevent a dry, crumbly crust.

Divide the Dough

Split the dough in half. Press one half evenly into the prepared pan, smoothing out highs and lows so the bars bake uniformly.

Spread the Filling

Use a spatula or offset knife to spread an even layer of chocolate sunflower spread across the bottom cookie layer. Don’t skimp—the filling is a highlight. Use a generous amount for a satisfying chocolate center.

Top and Bake

Crumble the reserved dough over the filling and press lightly so that some filling peeks through. Sprinkle sunflower seeds and a touch of sea salt on top if desired. Bake on the middle rack for 22–25 minutes, until the edges are lightly browned. Remove from the oven and allow the pan to cool; the bars will continue to set as they cool.

Slicing into Bars

Once fully cooled, lift the slab from the pan using the parchment paper. For clean slices, chill the pan in the fridge for about an hour, then slice into uniform bars. These also taste great cold straight from the fridge.

Final Thoughts

Making Keto Chocolate Sunflower Spread Stuffed Cookie Bars is straightforward and rewarding. These bars deliver the comfort of a classic cookie bar with keto-friendly ingredients, making them a perfect holiday treat or anytime dessert. With a tender crust, rich Chocolate Sunflower Spread center, and melty chocolate chips, they’re likely to win over keto and non-keto eaters alike.

Soft-baked cookie layers sandwich a generous layer of Chocolate Sunflower Spread for an irresistible low-carb treat.

Ingredients

  • 1 ¾ cup blanched almond flour
  • 1 tablespoon coconut flour
  • 1 teaspoon gluten-free baking powder
  • ¼ teaspoon sea salt
  • ½ cup sugar-free brown sweetener
  • ¼ cup sugar-free granulated sweetener
  • ½ cup sunflower seed butter
  • 2 tablespoons unrefined virgin coconut oil, softened
  • 2 large eggs, room temperature
  • ⅛ teaspoon pure vanilla extract
  • ¼ cup sugar-free chocolate chips
  • 5 oz chocolate sunflower spread

Instructions

  • Bring eggs to room temperature (30–60 minutes) or place in warm water for 5 minutes if short on time.
  • Preheat oven to 350°F and line an 8×8-inch baking pan with parchment paper.
  • Whisk almond flour, coconut flour, baking powder, and sea salt in a medium bowl.
  • In a large bowl, combine the brown and granulated sweeteners, sunflower seed butter, and coconut oil. Add eggs and vanilla and stir until smooth.
  • Slowly add the dry mixture to the wet mixture, folding until nearly combined. Fold in the chocolate chips. Do not overmix.
  • Divide the dough in half. Press one half evenly into the prepared pan.
  • Spread the chocolate sunflower spread evenly over the bottom layer.
  • Crumble the reserved dough over the top. Sprinkle sunflower seeds and sea salt if desired.
  • Bake on the middle rack for 22–25 minutes, until edges are lightly golden. Cool completely before cutting into bars.

Notes

1. Stir sunflower spread and sunflower seed butter thoroughly before measuring.
2. Parchment paper prevents sticking; grease the pan or use a silicone pan if unavailable.
3. Room-temperature eggs improve texture; warm them briefly in water if needed.
4. Mix until no streaks of flour remain—overmixing leads to dry, crumbly bars.
5. Different keto sweeteners can alter flavor; choose one you like for baking.
6. For a nut-free flour alternative, ground flaxseed may work but will require adjustment.
7. You can omit the filling and bake a single-layer cookie bar if preferred.
8. Use a pure sea salt with no additives for best flavor.
9. Carb calculations may vary by brand; the listed nutrition excludes sugar alcohols in net carb math.
10. Oven times vary; this recipe was tested in a U.S. gas oven.
