Rum Apple Tart with Salted Caramel

Dark rum goes in, apples soften, the whole kitchen smells like caramel and spice. That’s it. No fussy laminated dough. No waiting around. Just actual tart that tastes like you spent three hours on it.

Why You’ll Love This Rum Apple Tart with Salted Caramel

Takes 60 minutes start to finish — 35 minutes of actual work if you move. The caramel part matters. It’s not an afterthought. Sits on top, gets warm, pools in the corners. Walnuts instead of pecans because that’s what you probably have. Either works fine. Tastes better the next day. Flavors deepen. Weird but true. Weeknight dessert that feels like something. Not complicated. Just feels like it.

What You Need for This Apple Rum Tart

Two Crispin apples — they don’t fall apart when they cook. Regular apples get mushy. Don’t swap.

Dark spiced rum. Three and a half tablespoons. The kind you’d actually drink. Cheap stuff tastes like cheap stuff.

All-purpose flour — a cup and a bit. Baking powder. Coarse enough that you can actually measure it.

Two eggs. Coconut sugar because regular sugar works too, honestly. Melted coconut oil. Milk. Whole milk, not skim.

More butter and more sugar for the syrup that goes on top. Walnuts, chopped roughly — like a quarter cup. They stay textured. Don’t powder them.

For the caramel: granulated sugar, more butter, heavy cream. That’s the whole sauce. Salt goes in at the end. Not during. After.

How to Make a Rum Apple Tart

Heat the oven to 350. Middle rack. Get a springform pan ready — eight inches, lined with parchment on the bottom, sides lightly buttered or sprayed.

Dice the apples into rough pieces. Not tiny. Not huge. About the size of a thumbnail. Pour the rum over them and let it sit. Twelve minutes. Stir it halfway through. The apples should go soft at the edges but still hold their shape. You’ll know. After twelve minutes, pour off the rum that didn’t get soaked in. Save that liquid.

In one bowl, sift the flour and baking powder together. Set it aside.

In a bigger bowl, whisk the eggs and coconut sugar hard. Three minutes minimum. Use a handheld mixer if you have one. By hand takes longer but works. The mixture should get pale and thick — like the texture changed, not just got mixed. That’s when you stop.

Pour in the melted oil. Then the milk. Stir gently. Fold in the flour mixture in three parts, alternating with that reserved rum liquid you saved. Don’t go nuts mixing it. A few lumps are fine. The batter should be thick but pourable — not batter-batter, but not soup either.

Fold the drained apples in carefully. Keep them spread out. Don’t squash them.

How to Get the Tart Perfect and Golden

Pour everything into the pan and smooth the top with a spatula. Tap the pan on the counter a few times — gets the air bubbles out.

Bake for 22 to 27 minutes. Start checking at 20. Stick a skewer in the center. If it comes out clean or with just a few moist crumbs, you’re done. If wet batter sticks, keep going. The edges should be golden and pulling away from the sides just a bit. Press the center gently with your finger — it should spring back. Not jiggly. Not rock hard.

While it bakes, melt the reserved rum with coconut sugar and butter in a small saucepan over medium heat. It’ll bubble gently. Keep an eye on it. When it smells caramelized — not burned, caramelized — pull it off the heat.

The cake comes out. Immediately sprinkle the walnuts on top. Then pour that warm syrup all over. Let it cool for 15 minutes in the pan. Then loosen the edges and pop the springform off.

It’s better warm. Or room temperature. It’s also better the next day.

Rum Apple Tart Tips and Common Mistakes

Don’t soak the apples longer than 12 minutes or they get mushy. They should still have some give but not fall apart. Crispin apples matter here. They hold up.

The batter mixing — don’t overmix it. That’s the only way you actually mess this up. A few lumps are your friend. They disappear in the oven.

The syrup on top gets thick as it cools. If it looks like it’s not coating anymore, it’s still working. It’ll set more when the whole thing cools completely.

Check the cake at 20 minutes. Every oven is different. Some take 22. Some take 27. The skewer test is honest — use it.

The caramel sauce is separate, for drizzling on slices. Don’t skip it. It’s the whole reason the tart works. Warm it gently before serving if it gets too stiff in the fridge. Keeps a week.

Ingredients

• 2 Crispin apples peeled and chopped into rough 1 cm cubes
• 50 ml (3 1/3 tbsp) dark spiced rum
• 280 ml (1 1/8 cups) all-purpose flour
• 6 ml (1 1/4 tsp) baking powder
• 2 large eggs
• 55 ml (3 1/2 tbsp) coconut sugar
• 35 ml (2 1/3 tbsp) melted coconut oil
• 60 ml (1/4 cup) whole milk
• 50 ml (3 1/3 tbsp) coconut sugar (for syrup)
• 45 ml (3 tbsp) unsalted butter
• 130 ml (1/2 cup) coarsely chopped walnuts
• Salted Caramel Sauce
• 120 ml (1/2 cup) granulated sugar
• 65 ml (1/4 cup plus 1 tbsp) unsalted butter
• 240 ml (1 cup) heavy cream 35%

Method

1. Apple Rum Maceration
2. 1 Place oven rack in middle position. Preheat oven to 175 °C (350 °F). Line a 20 cm (8 inch) springform pan with parchment on bottom. Lightly grease sides with butter or nonstick spray.
3. 2 Combine chopped apples and dark spiced rum in bowl. Stir and let sit 12 minutes, stirring occasionally. Apples should absorb rum slightly but still hold shape. Drain off the rum liquid and reserve separately.
4. Dry Ingredients & Batter
5. 3 In a separate bowl, sift together flour and baking powder. Set aside. In larger bowl, whisk eggs and coconut sugar vigorously until pale, thickened and airy — at least 3 minutes. I use handheld electric mixer; beats by hand need extra elbow grease here.
6. 4 Add melted coconut oil, then milk into egg mix, stirring gently to combine. Fold sifted dry ingredients in 3 parts alternately with reserved rum liquid. Don’t overmix; few lumps ok. Texture should be thick but pourable.
7. 5 Fold the drained rum-soaked apples gently into batter with spatula. Keep fruit evenly distributed but avoid squashing.
8. Baking the Cake
9. 6 Pour batter into prepared pan, level surface with spatula. Tap pan lightly to remove bubbles.
10. 7 Bake 22-27 minutes, start checking at 20. Tester (thin skewer) inserted into center should come out clean or with few moist crumbs, not wet batter. Edges golden and pulling slightly from pan sides. Good poke test: center springs back, not jiggly but not dry.
11. 8 Meanwhile, melt reserved rum, coconut sugar, and butter in small saucepan over medium heat until bubbling gently. Once mixture thickens and smells caramelized, but not burned, remove from heat.
12. 9 Immediately sprinkle walnuts on cake surface, then drizzle warm syrup evenly over top. Let cake cool 15 minutes in pan before loosening edges and removing ring. Serve warm or at room temp; flavors deepen after resting.
13. Salted Caramel Sauce
14. 10 Spread sugar evenly over bottom of heavy-bottomed saucepan. Heat on medium without stirring; watch sugar melt and form amber liquid, swirl pan gently for even coloring. Avoid crystal formation—if crystals form, add drop water and start again.
15. 11 When sugar is deep amber, remove from heat and whisk in butter quickly. Mixture will bubble violently—stand back. Then slowly pour in cream while whisking. Return to low heat and simmer 4-6 minutes until sauce thickens slightly—should coat back of spoon.
16. 12 Remove from heat, let cool to lukewarm. Sauce thickens more when chilled; warm gently before serving if too stiff.
17. 13 Drizzle sauce generously on slices. Keeps refrigerated up to 1 week; gently reheat or bring to room temp before serving.

Frequently Asked Questions About Rum Apple Tart with Salted Caramel

Can I make the salted caramel sauce ahead? Yes. Make it days before. Refrigerates fine. Warm it gently in a saucepan before drizzling, or leave it out until it’s soft. Doesn’t have to be hot.

What if I don’t have dark spiced rum? Light rum works. Won’t taste the same. The spiced part matters more than the dark part. If you have neither, skip it entirely. Add a tablespoon of vanilla instead. Different tart, still good.

Do I have to use coconut sugar? No. Regular granulated sugar works. Brown sugar works too. Same amounts. Coconut sugar just browns a bit darker and tastes slightly deeper, but it’s not essential.

Why walnuts instead of pecans? The recipe calls for walnuts. Pecans work if that’s what you have. Different flavor but same texture. Doesn’t matter much. Use what’s in your cupboard.

Can I make this without the springform pan? Use a regular nine-inch cake pan. Grease and flour it. The tart will be thicker. Might take a few extra minutes to bake. Parchment helps it come out clean.

How do I know the caramel is done? It should be deep amber — like the color of old wood or dark honey. Not black. Not light brown. When you tilt the pan, it should move like liquid. Once it’s that color, pull it off heat. It keeps darkening as it cools.

What’s the rum-soaked apple tart taste like? Spiced. Sweet. A bit boozy but not aggressively so. The rum flavor sits underneath, not on top. The caramel on top is the main thing you taste first.
