Ingredients
The foundation of these squares is a blend of rolled oats, almond flour, and a touch of whole‑wheat flour, which together create a sturdy yet tender crumb. Fresh peach and raspberry add natural sweetness and a burst of color, while Greek yogurt and honey bind everything together and keep the texture moist. A light glaze of honey, lemon juice, and a splash of vanilla finishes the dish with a glossy shine.
Dry Base
- 1 ½ cups rolled oats
- ½ cup almond flour
- ¼ cup whole‑wheat flour
- 2 teaspoons baking powder
- ¼ teaspoon sea salt
Wet Mixture
- ¾ cup plain Greek yogurt
- 2 large eggs, lightly beaten
- ¼ cup honey
- 1 teaspoon vanilla extract
Fruit Mix
- 1 cup fresh peach, diced (about 2 medium peaches)
- ½ cup fresh raspberries
Glaze (Optional)
- 2 tablespoons honey
- 1 teaspoon fresh lemon juice
- ¼ teaspoon vanilla extract
Together, these components create a balanced bite: the oat‑flour blend gives structure, the yogurt‑egg combo adds moisture and protein, and the fruit supplies natural sweetness and antioxidants. The glaze adds a final glossy finish that makes each square look as good as it tastes.
Step-by-Step Instructions

Preparing the Dry Base
In a large mixing bowl, combine rolled oats, almond flour, whole‑wheat flour, baking powder, and sea salt. Stir with a whisk until the mixture is evenly speckled and any clumps are broken up. This ensures a uniform rise and prevents dense pockets in the final squares.
Mixing the Wet Ingredients
In a separate bowl, whisk together Greek yogurt, beaten eggs, honey, and vanilla extract. The yogurt adds a tender crumb while the eggs act as a binder. Whisk until the mixture is smooth and slightly frothy, indicating that the eggs have incorporated air for a lighter texture.
Combining Fruit and Batter
- Fold wet into dry. Pour the wet mixture over the dry ingredients and stir gently with a spatula until just combined. Over‑mixing can develop gluten from the wheat flour, leading to a tougher square.
- Add fruit. Gently fold in the diced peach and raspberries, being careful not to crush the berries. The fruit should be evenly distributed, creating pockets of juicy flavor throughout.
- Transfer to pan. Lightly grease a 9×13‑inch baking dish or line with parchment. Spread the batter evenly, smoothing the top with the back of a spoon. The surface should be level for uniform baking.
Baking
Preheat the oven to 375°F (190°C). Place the pan on the middle rack and bake for 28–32 minutes, or until the edges turn a deep golden brown and a toothpick inserted into the center comes out clean with just a few moist crumbs. The top should feel set but still slightly springy to the touch.
Finishing Touches
While the squares cool for about 10 minutes, whisk together the glaze ingredients: honey, lemon juice, and vanilla. Drizzle the warm glaze over the still‑warm squares, allowing it to seep into the cracks. Let the squares cool completely before cutting into 12 even portions. Serve warm or at room temperature.
Tips & Tricks
Perfecting the Recipe
Measure oats by weight. Using a kitchen scale (≈150 g) prevents over‑packing, which can make the squares heavy.
Pat fruit dry. Toss the diced peach in a paper towel to remove excess juice; this avoids soggy spots in the batter.
Use room‑temperature yogurt. It blends more easily with the eggs, creating a smoother batter.
Check doneness early. Ovens vary; start checking at 25 minutes to avoid over‑baking.
Flavor Enhancements
Add a pinch of ground cinnamon to the dry base for warm spice notes, or stir in zest of one lemon for extra brightness. A tablespoon of chopped toasted almonds on top before baking adds a pleasant crunch.
Common Mistakes to Avoid
Avoid mixing the batter too vigorously; it can develop gluten, resulting in a dense square. Also, don’t skip the cooling period before cutting—hot squares tend to crumble, while a brief rest lets them set and hold their shape.
Pro Tips
Line the pan with parchment. This guarantees a clean release and preserves the decorative top.
Use a silicone spatula. It folds the fruit gently without crushing delicate berries.
Glaze while warm. The glaze adheres best when the squares are still hot, creating a glossy finish.
Store in a single layer. Stacking squares before they’re fully cooled can trap steam and make the bottom soggy.
Variations
Ingredient Swaps
Swap peaches for sliced apricots or nectarines for a slightly different sweetness. Raspberries can be replaced with blueberries, blackberries, or even a mix of dried cranberries (rehydrated) for a tangier bite. For a nut‑free version, replace almond flour with oat flour or extra whole‑wheat flour.
Dietary Adjustments
To make the squares vegan, use plant‑based yogurt (coconut or almond) and replace the eggs with a “flax egg” (1 tbsp ground flax + 3 tbsp water per egg). For a gluten‑free version, ensure the oat flakes are certified gluten‑free and substitute the wheat flour with additional almond or oat flour.
Serving Suggestions
Pair the squares with a dollop of vanilla Greek yogurt or a splash of maple‑cinnamon syrup for extra indulgence. A side of fresh mixed greens lightly dressed with citrus vinaigrette balances the sweetness, making it an elegant brunch plate.
Storage Info
Leftover Storage
Allow the squares to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 4 days. For longer keeping, wrap individual squares in plastic wrap, place in a freezer‑safe bag, and freeze for up to 3 months. Proper sealing prevents freezer burn and preserves the fruit’s vibrancy.
Reheating Instructions
Reheat refrigerated squares in a 350°F (175°C) oven for 8–10 minutes, covered with foil to retain moisture. For a quick microwave fix, place a square on a microwave‑safe plate, cover with a damp paper towel, and heat on medium power for 30–45 seconds. Drizzle a little extra glaze after reheating for a fresh finish.
