Peach Crumble Recipe Without Oats: Buttery Almond Flour Topping

Summer peaches deserve a crumble that lets their natural sweetness shine through. This version skips the oats entirely, using almond flour for a topping that’s just as buttery and crisp as the original.

I developed this recipe after testing multiple nut-based alternatives, and almond flour emerged as the clear winner. It creates a golden crust that holds its shape while baking, with a delicate nuttiness that complements the fruit.

The filling stays juicy and fragrant, with just enough sugar to enhance rather than overpower. David declared this his new favorite after the first bite—high praise from my official taste-tester.

It bakes in under 45 minutes, filling your kitchen with the aroma of caramelizing peaches and toasted almonds. Serve warm with vanilla ice cream for the full experience.

Ingredients for Peach Crumble Recipe Without Oats

Ripe peaches and almond flour create a golden, buttery crumble worth savoring.

The peaches are the star here. Farmers market peaches in peak season are ideal—look for fragrant, slightly soft fruit (the good stuff, not rock-hard). Almond flour is widely available at Whole Foods, Trader Joe’s, or the baking aisle of most supermarkets. For the butter, Plugrá or Kerrygold give that rich, European-style flavor that makes the topping irresistibly crisp. Cold butter is non-negotiable—don’t let it soften.

No almond flour? Hazelnut flour works beautifully (even nuttier taste). Short on peaches? Nectarines or plums swap in perfectly. For a gluten-free version, replace the all-purpose flour with tapioca starch. The brown sugar can be light or dark—dark adds more molasses depth. Skip the cinnamon if you prefer, but it really ties everything together.

The crumble topping freezes well raw—just sprinkle over fruit and bake straight from frozen, adding 5-10 minutes. Baked crumble keeps 2 days at room temperature (cover loosely with foil). Best served warm, so reheat individual portions in a 350°F oven for 10 minutes.

Step-by-Step Instructions for Peach Crumble Without Oats

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Peach Filling

Peel and slice all 6 whole Fresh Peaches into even wedges. In a large bowl, gently toss the peaches with ¼ cup of the 0.5 cup Granulated Sugar, all of the 1 tsp Ground Cinnamon, the 1 tbsp Cornstarch, 1 tsp Vanilla Extract, and 1 tbsp Lemon Juice.

The cornstarch will thicken the natural juices as it bakes, creating a luscious filling rather than a runny one. Let this mixture sit for 10 minutes while you prepare the topping—this gives the sugar time to start drawing out the peach juices.

Step 2: Make the Almond Flour Topping

In a separate bowl, combine the 1.5 cups Almond Flour, 0.25 cup All-Purpose Flour, remaining ¼ cup Granulated Sugar, 0.25 cup Light Brown Sugar, and 0.25 tsp Salt. The all-purpose flour adds structure to the topping, while the almond flour provides that rich, buttery flavor.

Cut in the 0.5 cup Cold Unsalted Butter (cubed) using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized clumps. Don’t overwork it—you want those visible butter pieces for flaky texture when baked.

Step 3: Assemble and Bake

Transfer the peach filling to a 9×9-inch baking dish or similar, spreading it evenly. Sprinkle the topping evenly over the peaches, pressing down lightly to help it adhere. Don’t pack it down too firmly—you want the crumble to stay light and airy as it bakes.

Bake at 375°F for 35-40 minutes, until the topping is golden brown and the filling is bubbling at the edges. If the topping starts browning too quickly, tent loosely with foil to prevent burning while the filling finishes cooking.

Step 4: Rest and Serve

Remove from the oven and let it rest for 10-15 minutes. This allows the filling to thicken slightly as it cools, making it easier to serve. The topping will firm up slightly too, creating that perfect contrast between crisp crumble and tender peaches.

Serve warm with a scoop of 1 cup Vanilla Ice Cream on top, if desired. The ice cream melts beautifully into the warm filling, creating a creamy, dreamy combination that’s hard to resist. Each serving should have a generous portion of both peaches and crispy topping.

Perfect Pairings for This Dish

Dessert Pairings

Vanilla ice cream is the classic choice—I use Blue Bell Homemade Vanilla from Austin markets. Its rich, creamy texture melts perfectly into the warm peach filling. For a lighter option, Greek yogurt with a drizzle of honey adds a tangy contrast. 💛

Beverage Matches

Cold milk or sweet tea cuts through the buttery topping beautifully. I also love a crisp Moscato d’Asti—its peachy notes echo the fruit. For coffee lovers, a cold brew with a splash of cream balances the sweetness.

Breakfast Twist

Serve leftover crumble for breakfast with a dollop of whipped cream and a sprinkle of toasted almonds. David swears this is his favorite way to start the day. The almond flour topping makes it feel almost virtuous.

Cheese Pairings

A sharp cheddar or blue cheese might sound unusual, but the salty contrast works. Try Maytag Blue from the cheese counter at Central Market. The bold flavor stands up to the sweet peaches.
