These fall dessert bars layer diced pears and tart cranberries between a buttery oat base and a crumbly topping. The same mixture forms both the crust and crumble, so there is no separate pastry dough to roll. Cinnamon sits in the oat mixture, while lemon juice and vanilla season the fruit.
These bars have visible pear pieces and cranberry pockets rather than a smooth jam filling. Baking and cooling times are approximate; let the filling set fully before slicing.
Recipe at a Glance
- Estimated yield: 12 bars.
- Estimated prep: 20 minutes.
- Estimated baking: 50 minutes, including the base.
- Estimated cooling: 2 hours.
- Estimated total: 3 hours 10 minutes.
- Pan: 9-inch square metal baking pan.
The cooling period is part of the recipe. Cutting a hot fruit filling produces softer portions, so this is not a quick-total-time dessert.
Ingredients
- 1 1/4 cups all-purpose flour — 150 g.
- 1 cup old-fashioned rolled oats — 90 g.
- 1/2 cup packed light brown sugar — 100 g.
- 1 teaspoon ground cinnamon.
- 1/2 teaspoon baking powder.
- 1/4 teaspoon fine salt.
- 10 tablespoons unsalted butter — 142 g; melted and allowed to cool slightly.
- 3 cups peeled, cored and diced firm-ripe pears — 450 g prepared weight; dice into 3/8-inch pieces.
- 1 cup fresh or frozen cranberries — 100 g; do not thaw frozen berries.
- 1/3 cup granulated sugar — 67 g.
- 2 tablespoons cornstarch — 16 g.
- 1 tablespoon lemon juice.
- 1 teaspoon vanilla extract.
Weigh the pears after peeling and coring. A whole pear's weight includes the stem and core, and the number of pears needed varies with their size. Firm-ripe pears are easier to cut into even pieces than very soft pears.
Use old-fashioned rolled oats for the intended crumble texture. Steel-cut oats do not soften in the same way. This draft is not formulated with instant oats or a gluten-free flour substitute.
How to Make Pear Cranberry Bars
1. Prepare the pan
Heat the oven to 350 °F (175 °C). Lightly grease a 9-inch square metal pan and line it with parchment, leaving an overhang on two sides. Avoid a larger pan, which would make the base and fruit layer thinner.
2. Make the oat crumble
In a bowl, mix the flour, oats, brown sugar, cinnamon, baking powder and salt. Pour in the slightly cooled melted butter and stir until clumps form. Reserve roughly one-third of the mixture for the topping.
3. Set the base
Press the remaining mixture firmly and evenly into the pan. Bake for about 12 minutes, until the surface looks set. It does not need to be deeply browned.
4. Mix the fruit filling
While the base bakes, toss the diced pears and cranberries with granulated sugar, cornstarch, lemon juice and vanilla until the fruit is evenly coated and no dry pockets remain. Do this shortly before filling the pan so the pears do not release a large puddle of juice.
5. Add fruit and topping
Spread the fruit mixture and any small amount of juice evenly over the warm base. Scatter the reserved crumble in small clumps over the fruit.
6. Bake until bubbling
Bake for 35–40 minutes, or longer if necessary, until the topping is golden, the filling bubbles near the center, and a fork slides into a pear piece easily. If the top darkens early, cover loosely with foil. Frozen cranberries can lengthen baking.
7. Cool and slice
Rest the pan on a rack for about 30 minutes, then refrigerate to finish cooling and firm the filling, approximately 90 minutes more. Refrigerate within 2 hours of baking, or within 1 hour above 90 °F (32 °C). Lift with the parchment and cut into 12 bars only when completely cool.
Tips for Clean Slices
Press the base firmly into the pan, especially at the corners. Loose crumbs under a moist filling can make the bars fragile. Use parchment handles so the cooled slab can be lifted before it is cut.
Keep the pear cubes reasonably even. Large pieces take longer to soften and can push through a slice; tiny pieces can disappear into the filling. The 3/8-inch size is a practical starting point for this formulation.
Look for bubbling near the center rather than only at the outer edge. Cornstarch needs heat and moisture to thicken the fruit juices. A golden crumble alone does not prove the filling underneath is ready.
Use a sharp knife on the fully cooled slab, wiping it between cuts. If the filling remains loose after cooling, serve it as spoonable portions and adjust the formulation after a kitchen test; do not describe an untested recipe as guaranteed to slice perfectly.
Ingredient Choices and Variations
Bosc or Anjou pears are useful starting choices when they are ripe but still firm. The ripeness matters as much as the name on the sticker. Do not substitute canned pears without reformulating for their additional moisture.
Frozen cranberries can be used straight from the freezer. Allow extra time if the filling is not bubbling and the pear pieces are still firm. Dried cranberries are not a direct replacement for fresh fruit in this filling.
The flavor is intended to come from pear, cranberry, cinnamon and vanilla. An optional topping such as whipped cream belongs to serving suggestions, not to the base ingredient list or the required image.
Storage
Cool and refrigerate the moist fruit bars promptly using the timing in the method. Store in a covered container in the refrigerator at 40 °F (4 °C) or below and use within 3–4 days. Separate stacked bars with parchment.
Freezing texture has not been tested. If you try it, freeze a small portion first and thaw in the refrigerator to assess how the fruit layer and crumble hold up. The refrigeration limits follow USDA leftover guidance.
Frequently Asked Questions
Can I leave out the cooling time?
Cooling is needed for the intended bar format. Warm portions can be served with a spoon, but should not be presented as neatly set bars.
Can I use a glass pan?
This draft is formulated around a metal pan. Glass changes heat transfer, and thermal-shock precautions become relevant during cooling. Use metal for the first kitchen test rather than promising the same timing.
Is the filling supposed to be red?
Cranberries can release red juice around the pale pear pieces. The filling should still show fruit pieces; it is not intended to be an opaque, pure-cranberry jam.
Can I make these gluten-free?
This version includes all-purpose flour and oats. A gluten-free reformulation needs appropriate ingredients and testing; no gluten-free claim is supplied.
