Recipe Details
Prep Time: 20 minutes + 20 minutes to chill
Cook Time: 38–48 minutes
Total Time: About 1½ hours
Servings: 8
Ingredients
- 1½ cups all-purpose flour
- ¾ cup whole wheat flour (or almond flour)
- 1½ sticks (12 tablespoons) unsalted butter, softened
- ½ cup granulated sugar
- 2 large egg yolks, room temperature
- 1 teaspoon vanilla extract
- ¼ teaspoon almond extract
- ½ teaspoon fine sea salt
- ⅓ cup sliced almonds
- 1 (10 oz) jar Mrs. Ruth's Simply Blackberry Jam
Directions
- Whisk together both flours in a bowl and set aside.
- In a separate bowl, beat butter and sugar together until pale and fluffy, about 3 minutes.
- Beat in egg yolks, vanilla extract, almond extract, and salt until combined.
- Add the flour mixture and mix until a soft dough forms.
- Divide the dough in half. Press one half evenly into the bottom and up the sides of a 9–10” tart pan. Wrap the remaining half and refrigerate both for 20 minutes.
- Preheat oven to 350°F.
- Spread Mrs. Ruth's Simply Blackberry Jam evenly over the chilled crust.
- Remove the reserved dough from the fridge and crumble it over the jam in rough, uneven pieces.
- Sprinkle sliced almonds evenly over the top.
- Bake for 38–48 minutes until deep golden brown. Cool completely before slicing.
Tips & Notes
- Don't skip the chill: Chilling the dough firms it up so the crust holds its shape and the crumble stays crumbly rather than melting flat.
- Press evenly: Use the bottom of a measuring cup to press the crust into an even layer for consistent baking.
- Jam options: Mrs. Ruth's Peach Jam, Orange Fig Marmalade, or Very Berry Jam all work beautifully as swaps.
- Storage: Refrigerate leftovers covered for up to 4 days. Bring to room temperature before serving for the best texture.
Flavor Pairings We Love

- Pair with: A cup of Earl Grey or a glass of Prosecco for a proper Italian-inspired dessert moment
- Try also: A dusting of powdered sugar over the top just before serving for a bakery-worthy finish
