This strawberry buckwheat snack cake has been one of my favorite things to come out of my kitchen lately! It’s soft, lightly sweet, studded with fresh strawberries, and topped with a maple kasha crumble that adds a satisfying texture. The whole thing bakes in a 9×13 pan in about 30 minutes, and it works just as well for breakfast as it does for dessert. Naturally gluten-free and can easily be made vegan!

A Note From Kristen

A few weeks ago, The Birkett Mills sent me a box of their buckwheat products to try, and wow, the flour is noticeably fresher and more flavorful than what I usually grab off the store shelf, and the medium kasha had this deep, toasty quality right out of the bag. Once I started cooking with both, I couldn’t stop. This cake was one of the first things I developed with them, and it’s a good example of what quality ingredients can actually do. The kasha crumble alone is worth making just to have on hand. I hope you love this recipe as much as I do. Happy eating!

Key Ingredient Notes

A few quick notes on the ingredients that matter most. Find the full ingredient list and instructions in the recipe card below.

  • Buckwheat Flour: The base of the cake. Buckwheat is naturally gluten-free and has an earthy, slightly nutty flavor that works beautifully with fruit and warm spices. Despite the name, it is not related to wheat!
  • Plain Yogurt: Keeps the crumb moist and tender. Use dairy or dairy-free. Both work well here.
  • Maple Syrup: Sweetens the batter without making it heavy. It also adds a subtle depth that complements the buckwheat.
  • Fresh or Frozen Strawberries: Folded into the batter and scattered on top. They soften into jammy pockets throughout the cake as it bakes.
  • Kasha: Toasted buckwheat groats that form the crumble topping. After soaking and baking, they get crunchy and caramelized without needing oats. Medium grind works best.

Kristen’s Top Tips

  • Pat the cooked kasha dry before using it as the topping. Excess moisture will cause it to steam instead of crisp.
  • Once you add the wet ingredients, mix the batter just until combined to keep the cake tender.
  • Let the cake cool in the pan for at least 10 minutes before slicing. It will continue to set as it cools, making for cleaner slices.

Variations Worth Trying

  • Swap the strawberries for blueberries, raspberries, blackberries, or diced peaches.
  • Fold 1/2 cup chopped pecans, walnuts, or sliced almonds into the kasha topping for extra crunch.
  • Add 1/2 cup chopped dark or white chocolate to the batter for a richer treat.
  • Stir 1 teaspoon grated lemon or orange zest into the batter for a bit of brightness.
  • Replace the cinnamon in the kasha topping with cardamom, ginger, or pumpkin pie spice for a different flavor profile.

My Favorite Ways to Serve

  • Enjoy warm or at room temperature with a cup of coffee or tea.
  • Add a dollop of plain or vanilla yogurt for an easy breakfast or snack.
  • Serve with whipped cream, a dusting of powdered sugar, or a scoop of vanilla ice cream for dessert.
  • Top with extra fresh strawberries and a drizzle of maple syrup for a little something extra.

Method

  1. Preheat the oven to 375°F. Line a 9×13-inch baking pan with parchment paper and set aside.

Notes

Storage

Store leftovers covered at room temperature for up to one day, or refrigerate in an airtight container for up to 4 days. The kasha topping stays reasonably crunchy even after refrigerating. This cake also freezes well – wrap individual squares and freeze for up to 2 months. Thaw at room temperature or warm briefly in the oven.
Make it Vegan

To make this buckwheat cake vegan, simply swap the yogurt and butter for dairy-free versions of the same.
